I have an Acebeam Pokelit 2AA, a brilliant little light, my first true EDC light.

It uses a custom Lithium battery called ARC14100P-160A which has a USB-C charging circuit built into the top of the battery.

This week the battery died, I noted that the light didn't turn on with the battery, but with 2x 2AA NMIH it works.

When I connect it to charge, the charge LED just lights up green and the battery pulls no current (tested with my USB power meter), I tried to test the voltage of the battery with a multimeter, but it shows as 0 volts.

To me, all of this indicate an issue with the battery's protection circuit, as I believe even a discharged lithium battery should show some voltage.

Has anyone else seen this issue?

What weirds me out about this is that the charge LED just shows as fully charged when I connect it...

Is it trickle charging at that point, do I plug it in and leave it?

Attempting to charge an obviously malfunctioning battery is a fire/explosion hazard.

Acebeam has been working on its customer service lately, so you might convince them to send you a new one. Otherwise, 141000 is a semistandard size and you can buy them from several flashlight brands including Acebeam, Nitecore, Lumintop, Coast, and Thrunite. They all seem to be a bit overpriced.
