These are 2500mWh not mAh like most how rechargeable batteries are advertised. These would be around 1,667 mAh at 1.5v

That's true for all brands of rechargeable lithium AA/AAA sets. They are interchangeable with eachother but can't be charged with standard NiMh/lithium chargers and you can't charge NiMh/standard lithium batteries with these type chargers.

All rechargeable lithium AA/AAA batteries are 3.7v cells with built-in buck converters bringing the voltage down to a constant 1.5v. The charging/discharging/protection circuitry is built into the battery itself. The "charger" is simply acting as a DC power supply, outputting a constant 5v to each cell.

Batteries with a fixed voltage output, like these, with boost or buck drivers (the case here, bringing 3.7v down to a constant 1.5v), benefit from mWh ratings as its more accurate. You'd be hard pressed to find rechargeable lithium AA/AAA cells that are not rated this way.

Conversely, NiMH batteries aren't rated in mWh because their voltage drops significantly during discharge, making a single voltage rating misleading for energy storage.

I do not recommend this brand. Bought another charger and battery combo pack, only to find out that you need to use their batteries in their charger and vice versa. Reviews on this item are extremely fishy, too.

I worry about nonbranded lithium batteries, given the risk of fire during recharging. Save a bit of money but might lose your house. Personally I won't take that risk. Would just advise anyone buying these to keep a close watch on them while they charge.

Thank OP, Ordered, I'll give them a try. Curious though, can you charge single batteries, or like 3 at a time.. Most NiMh chargers require a pair of batteries to be charged. Never had Li , wondering if they still need pairs to charge...

Yes. With lithiums, each cell charges independent of eachother.

it is fairly common for a new vendor/manufactor to offer full refund via non-amazon chanel in exchange for review. some keeps their review standard, most dont. you just treat them as no review, and focus on 1 or 2 start reviews to see if those issues matter to you.

So the concensus is that this brand is very questionable?

Just spent $10 on 8x AA Energizer one-time use batteries. This seems like a great deal.
