![]() As you can see from the graph below, the results were consistently around 700mAh – bar the final cycle, which topped out at 800mAh. Batteries hold a charge for a long time, even when not in use. Like similar top-quality batteries, these come factory charged and also offer good reliability. For anyone that cannot decide on whether to get the general AA rechargeable batteries, or the ones made specifically for Xbox controllers, I'd. Best of the Best Energizer Recharge - AA Rechargeable Batteries Check Price Best for Everyday Use An ability to hold a charge up to a year in storage make these great for backup power. If you mean how long the batteries last before they inevitably, mine have lasted 2 and a half years. ![]() To measure longevity, I charged and discharged the batteries 50 times, taking a capacity reading every 10 cycles. I use Duracell rechargeable batteries too and if you mean per charge it can last me maybe 30-35 hours. Most batteries that I test score higher than the rating printed on the side of the battery itself. Here, I found that the initial capacity was 732mAh, which is just below the rated capacity. Next, I measured capacity using a high-drain test (600mA +/-20% with a cut-off voltage of 0.94V). First, I started by measuring voltage, which should be a minimum of 1.2V the result of 1.24V is just within. To see how well these batteries performed, I ran them through a set of standard tests using an Ansmann Energy XC3000 battery tester. Plus, if you use them in low-drain devices such as remote controls, you won’t lose a lot of power each day. That’s useful, as you can charge and store them, on standby for when you want to use them.

Head to the official site, and it says that the batteries will last for three years or 400 recharges. All of the official imagery shows that these batteries can last for 100 charges, which sounds poor. Longevity is important for rechargeable batteries, but the Duracell Rechargeable AAA 750mAh offer a relatively low number of charge cycles. Image Credit (Trusted Reviews) Design and Charges The Duracell Rechargeable AAA 750mAh aren’t quite as good: mid-level capacity and a relatively low number of charge cycles mean that the competition performs better. Just about the biggest name in batteries, Duracell has impressed with its Rechargeable AA batteries. Cycles These batteries are rated to last for 400 charge cycles.Type These are AAA NiMH rechargeable batteries.
