I bought some off of Temu and they didn't last a couple of hours in a smoke alarm. I was able to get a partial refund and keep the batteries. I put them in our electric lift chairs as backup in case we get stuck up when our electric goes out. Tried it once as a test and they kinda worked but I also had a regular 9 volt in the box too. I'll try them again sometime.
Verbatim plans to launch lithium-ion AA and AAA rechargeable batteries, along with a 9V battery. All models can be charged via USB-C, eliminating the need for a dedicated battery charger. Thanks to voltage conversion, the rechargeable batteries can replace standard disposable batteries.
