XTAR Rechargeable AA Batteries with BC8 1.2V/1.5V Charger (8pcs 4150mWh AA)

So far from my testings the batteries seems to work very well and last awhile which is nice. I haven't had any bad batteries in my batch but only time will tell. Charging speed is kind of what I expected from these batteries which can take a few hours. If the batteries last as long as they claim they should then these are a fantastic value for what you are paying for high performance rechargeable batteries.I will update this review if things happen

XTAR Rechargeable AA Batteries with Charger, 1.5V AA Lithium These batteries are holding up pretty well in the devices I'm using them in. The charger works very well, and shows the the status of the cells charging. The voltage is a constant 1.5VDC, until the battery is almost exhausted. The voltage will then drop to 1.10VDC to allow a low battery warning to show on your device. It will then run at this reduced voltage, until it cuts off and needs to be recharged. In conclusion, I'm very satisfied with these batteries and would recommend them for purchase.

4/15/2024 Review: Excellent batteries, been using them for outdoor cameras the last 4+ months and last as long, if not longer than Energizer lithium's, plus no waste. The one caveat is they need to be at the lower 1.2v state/discharged to charge back up. I'm sure this is due to an internal protection from overcharging, being lithium. 11/27/2024 Update: Approaching 1-Year Anniversary and I'm happy to report all 12 batteries are still performing exceptionally well. Rotating 8 batteries in outdoor cameras, usually last a few months, pending activity. Performed well through last winter, and hoping for the same this winter. Another 4 batteries have been going strong in a touchless toilet for the last 6 months, without being recharged yet.

Batteries struggle with charge length.

These batteries are great. I get tons of life out of a single pair, they're rechargable, and they deliver a constant 1.5V per battery until they reach 5% battery life at which point it drops to about 1.2V (which is still enough to give you a low battery warning on the GBC and let you know to be ready to switch 'em out). Before I used these my GBC was absolutely flying thru AA Duracell batteries. Now I have great battery life even with an IPS backlit screen and Everdrive cart. The game-changers on these are the constant voltage and the unmatched mWh/mAh rating (how long a battery lasts before it needs to be recharged).

No damage done, but the internal circuitry that drops the voltage down from 3.2 to 1.5 volts introduces RF noise into the radio, rendering it useless. Very disappointed. Should have known better... Aside from that, I suppose they are OK, but they are useless to me. Seller has not responded.

Works great if I could keep my family from throwing them away when they go dead. Yes of course I told them they are rechargeable and expensive. Nobody pays attention these days.

> XTAR rechargeable aa batteries with charger XTAR 1.5V battery 4150mWh aa battery with BC8 charger (~$63) These batteries have a built-in voltage regulator that constantly puts out 1.5v, but when down to 5% it drops to 1.2v. This function allows electronics to sense when the battery is low, and this works well. This battery also stores a lot of power, more than any NiMH battery, and is lighter weight being a lithium battery. And it charges fast in the charger. I burn through a lot of AA batteries, and these are the best I've found so far that are rechargeable.
