EBL Fast Lithium Battery
The EBL batteries have a 1000 recharge cycles, meaning they are very durable. They can carry 3000mAh charge and discharge at 3.7v. They add a mix-protection additive that protects the material from degrading when discharging, therefore, extending the lifespan of the battery. It improves low self-discharge, hence its ability to maintain a 75% of the charge even if left unused for a year.
EBL 18650 lithium Rechargeable Batteries
This pack includes 18650 Li-ion batteries of 3000mAh and a universal charger. The charger only works for Lithium batteries and no other types. The charger uses the MU technology that provides a constant voltage and current for the safety of the battery it’s charging.
EBL AA & AAA Rechargeable Battery
These batteries achieve two to three times the capacity of other NiCD cells of the same size. They are designed for durability. It is suitable for those seeking more charge cycles and higher energy density. It is a good choice to control battery costs since it can be recharged more than 1000 times to power your devices. They are also recyclable meaning they are conscious of the environment.
EBL 85Bay 9V Li-ion Battery charger
The best choice to recharge your batteries is an EBL charger. This product can charge up to 9V batteries concurrently. It uses MCU technology to provide constant voltage and current for safety in charging. Once it reaches 8.1V, the charging will trickle till it is fully charged. The charger is compatible with 9V 6F2Li-ion rechargeable battery.
The rechargeable battery is made from the highest-quality material. The 400mAh battery can be used in calculators, GPS, digital cameras, and home security systems among other applications. It is RoHS and CE certified and comes with a 30-day money back guarantee.
The charger has inbuilt battery protection and a system to detect a fault. The smart LED indicators show the charging status from the start till when it is fully charged. It takes an input of 100-240V and gives an output of 4.2V at a current of 600mAh.
Fast Lithium Battery Charger
Use this charger to charge Lithium battery and not the other battery types. This package includes two universal Li-ion charger and 4000mAh Li-ion batteries. It takes about 4-hours to charge and when it is done the LED indicator will turn green.
A good deal on AAA batteries
There was no real difference in AAA battery performance between Energizer, Eneloop, Duracell, and these. These will probably be the cheapest, but if you see a better deal on another brand, they’ll serve you just as well.
Energizer, Eneloop, and Duracell also performed nearly identically, so it’s worth checking their prices before buying.
When we measured initial capacity by charging and discharging each battery three times and averaging the results, there was only an percent difference between the capacity of the best and worst brands. In this case, an percent spread is basically nothing. When we charged and discharged them another four dozen times—about 200 hours each—we also found that there was no drop in performance, or difference between brands, after the 50th cycle. We also tested which battery powered our favorite headlamps brightest and longest. After six hours, all four brands were dimming at a similar rate but still just barely lighting the way. It was long enough and close enough that the test ended in a tie.
Even after nine months on the shelf, all our batteries still had more energy left in them than any disposable AA battery has fresh from the factory.
In addition to technology improvements, the price of rechargeables has come down considerably. Even after including the cost of a new charger, your first set of eight AA batteries will pay for themselves in five to six recharge cycles compared with buying most name-brand disposables. And the benefits go beyond your wallet: Globally, over billion alkaline cells are made every year (PDF), and roughly half are purchased in the US (PDF). That’s an average of 4batteries per US household per year. Over four years, that would mean 1rechargeable batteries take the place of 18disposables—not a bad way to save some money (and the environment).
The only persistent drawback to rechargeables is that they still take a long time to recharge. Properly charging batteries takes time if you want to preserve their long-term performance—about eight hours for our AA pick. Technically, the faster you charge your batteries, the less life you’ll get out of them, though with modern batteries and chargers, the difference is likely negligible. There are many “fast chargers” available, but we don’t recommend them, as they degrade rechargeable battery life.
Instead of a faster charger, we recommend buying an extra set of batteries. Figure out what device takes the most batteries and buy that many extra. If you always keep the extras charged and sitting next to—not in!—your charger, they’ll be there when you need them. Rotating batteries this way is like having a perpetually stocked supply without going to the store.
How we picked
Batteries don’t require hours assessing industrial design or critiquing the user interface. They’re pretty straightforward, and they have to match a fairly precise set of dimensions. We wanted to find the best, most quantifiable value—a reliable mix of capacity, life, price, and availability.
There are a handful of different battery technologies out there right now, but the only ones that will truly replace your alkaline AAs are nickel-metal hydride AAs, commonly abbreviated as NiMH. (You can pronounce it “nim” and save some trouble.) Specifically, look for new NiMH batteries that advertise “low self-discharge,” “LSD,” or even “Precharged!” that will hold a charge for months or years as opposed to mere weeks.
Testing methods and results
We found our picks through a mix of standardized measurements and real-world performance. Standardized measurements help us get hard, comparable numbers for how much energy a battery can hold, how long it can hold it, and how it performs after constant charging and discharging. That’s helpful for relative comparisons, but to relate that to the real world we also load batteries into flashlights, headlamps, RC cars, and anything else we can think of to demonstrate head-to-head performance variations.
Our first bench test was straightforward. We discharged four batteries from each brand so we’d clear out whatever charge was left from sitting on the shelf. Then we charged them and discharged them three times to average the results. The speed at which a battery is charged and discharged actually impacts the amount of energy it will store, so we standardized both rates to match the gentle rates that simple chargers often use. This meant charging at 500 mA (.5A) for AA batteries and 400 mA (.A) for AAA batteries. Depending on your use, you could be discharging batteries quickly (e.g., photography lighting, RC cars) or slowly (e.g., wireless keyboard). Because AA batteries are likely the choice for more-demanding devices, we discharged them at 1,000 mA (A) rate, but we stuck to just a 400 mA discharge for the smaller AAA batteries. With such a huge range of possible uses, it’s impossible for us to have data for all of them, but a standardized test like this is still useful for comparing batteries to one another.
Care and use
With the right charger, your batteries will mostly take care of themselves. LSD NiMH batteries don’t need be kept in the refrigerator or freezer, you don’t need to drain them before recharging, and they don’t need trickle charging to hold power. If you use one of our recommended chargers, the only care they need is to be taken off when they’re done charging to avoid power leaking into and overcharging them.
Long-term test notes
We used the Energizer Recharger Power Plus batteries in our mice and keyboards for most of 201without any problems or unexpectedly short run times. Because NiMh batteries have a different voltage curve than alkaline batteries, we have noticed that simple battery meters, like the one that warns of low battery on macOS when using an Apple Magic Mouse or first-gen Magic Trackpad/Keyboard, can be confused about how full they are. We’ve learned to ignore the low-battery warnings and to continue to use the same batteries for a couple more weeks—if not months. Overall, the charge capacity life of our picks should be three to four times that of a standard disposable alkaline, but no matter what brand you use, be prepared for charge meters expecting alkalines to behave a little funky with NiMHs.
The new Powerex Precharged AA batteries performed well in all our bench tests, with 2,470 mAh (Wh) available for discharge of 2,600 mAh (3.Wh) of stated capacity. That’s over 2percent higher than either of our picks in terms of raw capacity, but you’re really paying a premium for that extra energy. The new batteries are retailing for roughly a dollar more per battery than our top pick—a huge difference if you want to stock up. If you have a specific need for the extra capacity, and don’t mind the cost, we’re sure they’d be great. But they’re just not necessary for what most people need around the house.
The AA Duracell Rechargeables were the only batteries to have a higher available capacity than the packaging claimed—2,47compared with 2,400 mAh—but they were in sixth place on our flashlight test, lasting just 2:4Finding the current generation for sale anywhere other than Walmart is surprisingly hard, and their retail price averages about 4cents more per battery than our pick.
The EBL 8-pack High Capacity 2,800-mAh Ni-MH Rechargeable Batteries are among the least expensive AA batteries we’ve found, and they had the highest available capacity in all our tests. At an average of 2,48mAh (Wh), an EBL bests our pick by a good 1percent. But because of the technological trade-off between capacity and longevity, we’re not willing to put much stock in their cycle claims: 1,200 in some places and 1,500 in others.
The Panasonic Eneloop Pro line is a higher-capacity, lower-cycle-life version of the AA Eneloops, rated for 2,550 mAh and 500 cycles compared with the standard 2,000/2,100. But an Eneloop Pro is the most expensive of our group, offering only percent more available capacity than our pick despite costing about 2percent more. Higher capacity and lower cycle life is important in some situations—photographers might want to in squeeze every flash they can between battery swaps. In general, though, this isn’t a good trade-off for most people and isn’t worth the premium price.
Special thanks to Jamie Tennies and RC Hobby and Raceway for soldering our test packs and giving us track time for our testing.
High recharge cycle
This refers to how many times you can recharge the batteries before you have to replace them outright. Five hundred times is a good minimum, but you will find batteries which can be recharged for 2,000 or more times. If you do the math, you can figure out exactly how long a recharge cycle will last you. Often you can go years before you have to replace your batteries.
Some rechargeable batteries undeniably yield better performance than others. You can recognize the quality especially when you are using a digital camera. Poor quality batteries result in poor quality photos. High-quality batteries result in crisp, distortion-free photos. This is true even with the same type of battery; not all lithium batteries are equal, for example.
Streamlight 44900 Waypoint Spotlight
The Streamlight is clearly designed for usage on boats and similar crafts, since it offers IPXwater resistance and an ability to float if dropped in water.
As far as power is concerned, this is a slightly different option when compared to the other more common lithium battery powered options. This rugged black and yellow colored spotlight is powered by alkaline batteries, the “C” size ones. You need four of them to keep light running for up to 8.hours. There is also an option of using a 12V DC power cord. The batteries are not included with the package.
As for the LED in use, it emits 2lumens at high beam and 20 at low beam. That should be more than enough in a nautical setting, especially when you take into account the highly effective, long range parabolic reflector on this spotlight. The rugger device has a tough polycarbonate body and lens designed to withstand severe impacts and shocks.
Cyclop Sirius 500 Lumen Handheld Spotlight
With a matte all-black finish and a pistol-grip replete with a trigger guard, this spotlight looks very close to a handgun if not for the unduly fat barrel that makes up the LED lights. And there are a lot of them too, with separate LEDs for different ranges.
As its name suggests the Cyclops has high power Cree LEDs taking care of the long range lighting while leaving weaker LEDs to handle the illumination when looking at nearer objects.That obviously implies that this spotlight has modes, off, long distance and short range lighting. The rechargeable battery offers hours of run-time on the more powerful Cree LEDs while the dimmer LEDs can last for around 1hours max on a full charge.
The battery is a 6V lithium polymer SLA with 2.5Ah. For more subtle usage, you even get a detachable red lens. And at 1.5lbs, this is a very lightweight and compact spotlight that is very easy on your hands.
Sirius Cyclops CYC 9WS Thor Watt LED Spotlight
Sirius spotlights tend to have a separate LEDs for high and low beam and this model is no different. It has Luxeon high power LEDs, three of them, for the high beam.
The weaker low beam functionality is handled six Nichia LEDs of a standard configuration. The high beams throws 300 lumens, which is a bit on the lower side when compared to the competition. But the high power LEDs are capable of producing adequate lighting for all but the most demanding users. The spotlight uses rechargeable batteries, and you get a home charging option as well as a car charging option, making this a fantastic choice for a flashlight to keep in your car, especially if going on long trips.
The grip is rubberized and easy to hold, and the gun-like trigger has an always on feature. The spotlight uses up all the battery in hours if used in high beam setting. There is also a discreet detachable red lens.
Requires AA batteries
With almost 750 lumens at high beam, this is one of the more powerful units we have reviewed.
This spotlight uses an in-built lithium ion battery pack capable of reaching full charge in hours. It will give you close to hour of run-time on high beam, and around hours on the lower setting. It can hold charge for up to 1months and can be charged using either AC or DC power sources.
Lithium-Ion (Li-ion) cells are by far the most common type of camera battery. The main reason for this is that they are extremely lightweight, can be recharged many times over and are capable of delivering a higher than average voltage than other cell types. In addition, subject to being stored at a reasonable temperature they are also much less prone to self-discharging when not in use.
Flash Power Packs
If you shoot with flash on location a lot, then it may be worth investing in a dedicated flash power pack. These are essentially bigger-capacity batteries that produce more power for faster recycling times, meaning you are free to use your flash to capture the moment without having to wait so long for it to charge in between shots.
To get the longest flight times you should use the largest battery (in terms of capacity) that you possibly can, but still keep within the maximum takeoff weight of your drone. For more details on finding out what your maximum takeoff weight is for your drone have a look at our guide on how to choose motors, propellers and ESC for your drone. The other thing to take into account is the physical size of the battery, as depending on what drone you are using you will only need be able to fit a battery of a certain size.
How to find the optimum C rating
As choosing the battery is often the last step to building your own drone, we will already know what motors and ESC we are using. Since the motors will draw the most amount of energy from your battery we can base our calculation around this.
By looking at the specs of your motors, in particular the thrust data tables you will be able to see what the motors maximum current draw is. As an example, our quadcopter (motors) weighs about 2Kg in total (with battery and all other equipment), the quadcopter will hover when each motor products about 500g of thrust. Since we are using the MT221motors with inch propellers we can look at the thrust table to see the motors current draw at maximum thrust, which turns out to be just under 10A.
Number of batteries
The number of batteries you decide to use on your drone does not ultimately make much difference as there are pros and cons of using more batteries. Firstly using more batteries has an added layer of safety as if one battery should fail, you still have another that you can use to quickly land. Also if you have the flexibility of replacing one battery if one of them gets older than the other. Charging time can be reduced if you have two chargers as each one can charge at the same time. However using two batteries can be more complex to mount and wire and buying two batteries can sometimes be more expensive than buying one. So ultimately using one ore more batteries comes down to the drone your are using and your own preference.
Li-ion Battery FAQ
Capable of high current pulses.
Applies to discharge only; charge temperature range is more confined.
Maintenance may be in the form of ‘equalizing’ or ‘topping’ charge.
Cost of battery for commercially available portable devices.
Derived from the battery price divided by cycle life. Does not include the cost of electricity and chargers.
Observation: It is interesting to note that NiCd has the shortest charge time, delivers the highest load current and offers the lowest overall cost-per-cycle, but has the most demanding maintenance requirements.
Good low temperature performance.
Forgiving if abused — the NiCd is one of the most rugged rechargeable batteries.
Economically priced — the NiCd is the lowest cost battery in terms of cost per cycle.
Available in a wide range of sizes and performance options — most NiCd cells are cylindrical.
Relatively low energy density — compared with newer systems.
Memory effect — the NiCd must periodically be exercised to prevent memory.
Environmentally unfriendly — the NiCd contains toxic metals. Some countries are limiting the use of the NiCd battery.
Has relatively high self-discharge — needs recharging after storage.
The Lithium Ion battery
Pioneer work with the lithium battery began in 191under G.N. Lewis but it was not until the early 1970s that the first non-rechargeable lithium batteries became commercially available. Lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest energy density per weight.
The high cell voltage allows battery packs with only one cell. Most of today’s mobile phones run on a single cell, an advantage that simplifies battery design. To maintain the same power, higher currents are drawn. Low cell resistance is important to allow unrestricted current flow during load pulses.
Moderate discharge current.
Subject to transportation regulations — shipment of larger quantities of Li-ion batteries may be subject to regulatory control. This restriction does not apply to personal carry-on batteries.
Expensive to manufacture — about 40 percent higher in cost than NiCd. Better manufacturing techniques and replacement of rare metals with lower cost alternatives will likely reduce the price.
Not fully mature — changes in metal and chemical combinations affect battery test results, especially with some quick test methods.
The Lithium Polymer battery
The Li-polymer differentiates itself from other battery systems in the type of electrolyte used. The original design, dating back to the 1970s, uses a dry solid polymer electrolyte. This electrolyte resembles a plastic-like film that does not conduct electricity but allows an exchange of ions (electrically charged atoms or groups of atoms). The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte.
The dry polymer design offers simplifications with respect to fabrication, ruggedness, safety and thin-profile geometry. There is no danger of flammability because no liquid or gelled electrolyte is used. With a cell thickness measuring as little as one millimeter (0.03inches), equipment designers are left to their own imagination in terms of form, shape and size.
Unfortunately, the dry Li-polymer suffers from poor conductivity. Internal resistance is too high and cannot deliver the current bursts needed for modern communication devices and spinning up the hard drives of mobile computing equipment. Heating the cell to 60°C (140°F) and higher increases the conductivity but this requirement is unsuitable for portable applications.
To make a small Li-polymer battery conductive, some gelled electrolyte has been added. Most of the commercial Li-polymer batteries used today for mobile phones are a hybrid and contain gelled electrolyte. The correct term for this system is Lithium Ion Polymer. For promotional reasons, most battery manufacturers mark the battery simply as Li-polymer. Since the hybrid lithium polymer is the only functioning polymer battery for portable use today, we will focus on this chemistry.
Rechargeable batteries have improved dramatically over the past few years. Now there are several different kinds, each providing a best match for various types of uses.
Do Not Use household-size rechargeable batteries in emergency equipment (flashlights, radios, emergency medical devices, smoke detectors, monitors) or in difficult-to-access areas. It is easier to monitor the remaining voltage in disposable alkaline batteries because it drops at a predictable rate while they are in use, but the power in a rechargeable battery remains steady until nearly completely discharged and then drops precipitously.
Rechargers: Match the recharger to the specific type and size of battery. For example, use only NiMH batteries in a NiMH charger, and match the battery size (e.g., AA, C, D) to the recharging compartment.
One thing I just noticed with my 16340 cells…
You want to match the cells for longest run time and to avoid the possiblity of one cell being low ( or a bad cell) and causing a cell reversal. Remeber that the cells come off charge about 4.3v or so and settle to values like above… but their useful run is like about 1v+ and they are considered dead at about 2.9v+/-.
Here’s the link for what TomMac and I are using
They have a much higher mAh rating than many (most/all?) of the others. Even if the camera is a heavy draw, leading to a lesser projected runtime, these are ~3x the rating of the others so one can reasonably expect longer battery change intervals. My initial installs didn’t last long but then I was still trying to adjust video lengths, positions and sensitivities, not to mention very cold temps. Also, the has been a camera firmware update. The combination of the firmware, moderating temps, and less putzing around has led to seemingly great battery life although it’s still too early to report actual results.
So far the new sw on the cameras is making me believe the ‘battery bug’ has been swatted.
First of all thanks for reading my article to the end! I hope you find my reviews listed here useful and that it allows you to make a proper comparison of what is best to fit your needs and budget. Don’t be afraid to try more than one product if your first pick doesn’t do the trick.
