New 2 x Rechargeable 10440 AAA 3.7V Li-ion Battery

Ordered cuz the other 10440’s with 5 stars was sold out for a while, it’s the same brand tho. Delivery was fast, batteries worked just fine. Ran em thru my battery charger/tester, xtar vc4 plus. Capacity is true they showed 325mAh and 330mAh. Will keep buying this brand when/if they die eventually, will update if anything changes.

Used these for a custom Raspberry Pi Zero 2 W portable emulator "gameboy" type system.2x of these at 700mah gets me a decent battery life of 2-3 hours depending on what game I am playing. Recharges with an external battery charger or my Adafruit PowerBooster 1000c over USB C

The pictures indicate them to be unprotected button top batteries. That is not what i got. They do not work in the flashlight i bought them for. They are too long. They may work well but i guess ill never know.

I use one of these with a dummy cell to better power a handheld pen style screwdriver. It regularly uses two normal AAA. But one of these rechargeable Lithium cells provides more than two AAA in voltage. So, use only one, and a AAA pass through cell.

Two cells tested #1 293mah #2 289mah definitely not 350mah.

I use a single one of these to power the custom handheld lasers that I build. With the driver's higher current draw, they don't last super long. But, that's to be expected as they have only a 300 mAh rating. Still, it's hard to beat building a multi-watt laser, the size of an ink pen, that will engrave material almost instantly. Would I buy these again? What do you mean would I? I already have, a few times actually. I probably will again in the future as well.

Good little batteries. Holds charge and works well. No protection.Edit: 03/08/2022 - I am still using these batteries in my EDC LED flashlight. They haven't degraded at all yet. They get daily use and have both been recharged numerous times. Would still recommend all day long.

I wasn't too sure based on picture alone, but they are button top.
