HW Rechargeable AA Batteries with AA/AAA Charger, [1.5V, 8-Pack] 3500mWh Double A Lithium Battery Charger High Capacity, Cargador de Baterias for Toys, Keyboards, Doorbell, Remote Controls, etc.

LOVE these AA batteries! They last so much longer than store bought batteries! I use them in my RC remotes and haven’t had to charge them since I put them in my radio. Highly recommend!

As a 25 year veteran of the audio engineering world, I've always been anti rechargeable batteries in wireless mics, but thought I should try a Li-ion option. I bought these as a test for our wireless mics at the church. We burn through hundreds of batteries a year in the Sennheiser EW series wireless. These last a bit longer than a good Alkaline, but then get to be recharged as opposed to put in the bin. The biggest downside is that they maintain their voltage until right before they die, so battery metering is essentially useless. You need to test run time before you stick them in critical roles. I tested on a single mic for a couple months before rolling out to the entire vocal team. We are now almost 9 months into using them weekly without any hiccups. Surprisingly, I highly recommend - at least for wireless mics and IEM packs.

Solid batteries and time will tell the number of cycles of charge. Only had it for a couple of months. I like the fact that the charger has light that shows battery charge status per battery, which I find useful to not overcharge batteries.

Good product

Used in a Blink Outdoor Camera in Northeast Ohio conditions. Installed on 3/01/2025. First recharge needed on 1/23/2026, which is solid performance given cold winters and year-round outdoor use. No issues so far. Will update if any problems come up.

I have a few sets of these. Working great in my Blink outdoor cameras. Last a long time and way more cost effective than throw away batteries.

Very poor, high fail rate. Don't be fooled. Use a good battery tester and you'll see: cheap batteries are not worth the price.

Best gift for my husband. Work great for his trail cameras.
