![]() ![]() Charger: IncludedNickel batteries are great for many things, but sometimes you need to guarantee full power, right up until they’re depleted.ĮBL 9-Volt Lithium Ion Rechargeable BatteriesBest 9-Volt Rechargeable BatteriesĬapacity: 3,200mWh (AA), 800mWh (AAA) The downside? These larger sizes require a separate charger like this one from EBL.If that describes you, then consider Deleepow’s Rechargeable Lithium Batteries. Available in packs of four with or without a charger, in both AA and AAA sizes, these batteries will provide consistent power at 1.5V. The thing to keep in mind is that these are rated in milliwatt hours, not milliamp, like nickel batteries. 3200mWh translates to about 2,100mAh, so the overall time between your charges will likely be less than with a traditional Ni-MH battery. Maintaining full power does come with some sacrifices, but it’s necessary for electronics like drones. Charger: IncludedAll of the batteries in this list so far have required wall chargers, but if you don’t have an outlet to spare, the EBL USB Rechargeable AA Lithium Ion Batteries are likely a good choice.ĮBL USB Rechargeable AA Lithium Batteries Best USB Rechargeable BatteriesĬapacity: 3300mWh (2200mAh) Lithium rechargeable batteries also often output at higher voltages, which is useful for high-powered devices.Every battery has its own micro-USB connection and the package comes with a handy 4-in-1 charging cable to plug them all in at once. Since they’re all lithium ion, you can count on power that won’t weaken over time and a fast, two hour recharge time. These batteries also pack a lot of juice. Rated at 3300 mWh at 1.5V, that translates to 2200mAh of consistent power. They’re also rated for a full 1200 recharge cycle, so should last for years into the future. The downside? They’re only available in AA. What To Look for in Rechargeable BatteriesWhen shopping for rechargeable batteries, there are a handful of key things you’re going to want to keep in mind: capacity, battery type, lifespan, and the reputation of the manufacturer. Here’s a quick breakdown of what to look for when purchasing rechargeable batteries. It is most frequently rated in milliampere/milliamp hours (mAh) and reflects how much charge the battery can hold. How long that battery will last depends on its milliamp rating and how much power the device requires. A remote control car will drain your batteries far faster than an Xbox One controller, for example. As a rule, you’ll want to buy the highest milliamp hour battery you can afford. ![]() Most rechargeable batteries use Nickel-Metal Hydride (Ni-MH).Īlong with that, you need to consider what type of battery will best match your needs. This makes the batteries more affordable but their power output drops the weaker the battery becomes. Other batteries use Lithium, similar to those in your smartphone, and avoid this but at a higher price. Be aware, lithium batteries are often rated in milliwatt hours, which can make their capacities seem larger than they really are. ![]() Be sure to use a calculator when comparing between different lithium-ion batteries. ![]()
