Our Picks for the Best Rechargeable AA Batteries Using one with the incorrect chemistry type may damage your batteries, so be sure to always use the charger that comes with the batteries or one that the manufacturer recommends. Keep in mind that while different rechargeable AA battery chargers are technically interchangeable, different chargers are designed for different batteries with different chemistry types. You’ll have to buy and supply your own charger separately in these cases since you otherwise won’t be able to recharge them when they’re depleted. But if you’re trying to get the best performance from your batteries, it’s best that they all match.ĭo all rechargeable AA batteries come with a charger? For most applications, this isn’t a huge deal.

Consistency: Cheaper rechargeable batteries tend to suffer from inconsistent capacities and lifespans.If you want a set of rechargeables for low-power electronics or something that’s going to sit in storage, then you’ll want to buy a brand that’s known for a low self-discharge rate. Self-Discharge Rate: As odd as it sounds, rechargeable batteries can vary widely in quality, which includes the self-discharge rate. Rechargeable batteries of all types slowly lose their charge while not in use.If you tend to burn through batteries, then look for a set that’s rated for around 500 cycles. In most cases, the time that it takes for a battery to break down is rated in terms of recharge cycles (how many times the battery is drained and recharged). Cycles: Rechargeable batteries slowly break down every time they’re used.It’s like comparing old and inefficient filament lightbulbs with new LEDs.)

But alkaline batteries drain faster than rechargeables, so their higher raw capacity doesn’t mean much. (To be clear, the average raw capacity of alkaline AAs is 2,500-higher than rechargeables. If you want a battery that works well with power-hungry electronics, get one with an above-average capacity. Most rechargeable AAs have a 2,000-mAh capacity.

Capacity: Rechargeable AA batteries last longer per charge than disposable batteries.

What should you look for in rechargeable AA batteries? This makes them especially great for high-drain electronics that otherwise run through batteries extremely quickly. This means you won’t have to constantly spend money on brand-new batteries whenever you run out. Since the batteries can be recharged, they’re reusable, unlike most batteries. There are several good reasons to buy rechargeable AA batteries over regular ones. ✓ Amazing temperature resistance (-4 degrees F)Ĭronislaw Buying Guide for Rechargeable AA Batteries DAMRONG RATTANAPONGĪA batteries are one of the most commonly found types of batteries in the average household, used in everything from remote controls to electric toothbrushes to alarm clocks and much more.
