HW Rechargeable Lithium AAA Batteries with USB Charger, 4 Packs 1.5V Li-ion AAA Battery, 1 Hour Fast Charge with USB Cable,1000 Cycles Charge Life-Span,4 Packs

This was the 2nd ever rechargeable Lithium battery replacement for standard batteries, I've purchased so far. My first was 9V rechargeable replacements and they've worked great. This have been recharged twice so far and work great.They last quite long in low current uses. NiMH and NiCad batteries only worked well in high drain applications, but are terrible in low drain applications since they self discharge too quickly. These lithium batteries don't self discharge like that and can last quite a long time. I expect them to last a decade or more, much longer than the NiMH and NiCad batteries. I can save a bunch of waste and some money by not needing to buy too many alkaline batteries in the future.

These arrived quickly and took a charge with no issues. I have been using them and have had no problems as of yet.

Great idea. I had to purchase these over than normal batteries the moment I saw them. I like to conserve our world and batteries, do not do that. Unfortunately, the batteries will not work in the specific remote I bought them for. They do, however work with other items. It’s a try and see for each. I do wish the charger cord were a bit longer.

Need batteries, but if you don’t have time to go to the store to grab batteries, you have these guys which I rechargeable by USB-C connectors

Works great!!

These are the best rechargeable batteries I have every owned! I've had them for over a year and they hold a charge forever. I use them in my audio recording gear and they last for days. Just ordered more.

I will never buy regular batteries again after buying these. If you’re tired of constantly wasting money on batteries these are definitely for you!!! When they are fully charged they last in my blink doorbell camera for 6-8 weeks before needing switched out with fresh ones. They also work great in the camera on my blink floodlight camera. When the traffic passing my house isn’t crazy because of a detour they last 5-6 weeks. But even with the detour and the camera constantly going off 24 hours a day they still last 3-4 weeks before needing replaced. Charging is easy since they come with a cord that has 4 connector and they charge all together. Charging does take about an hour to an hour and a half but that’s nothing compared to how long they last.

**UPDATE**10-27-24I thought these batteries were great but yesterday I plugged them in to charge by the supplied 4 in 1 squid cable and one of the batteries immediately started to smell like an electrical burning smell and the photo is the result. It melted down but didn't catch fire but I would still call that a definite fire hazard.I needed to replace a pair of non rechargeable AA lithium batteries in a Blink doorbell camera which lasted about a month. I didn't want to buy lithium AA batteries that I'd end up throwing away and at this rate I'd probably go through a pair a month which could get very expensive so I started looking for rechargeable lithium AA batteries and so far these batteries deliver great performance equal if not better than the disposable lithium major brand (starts with an E and it was the commercial grade batteries) and the best part is I have 2 more already charged and ready to go when it comes time to charge the pair installed now. Also at this price it's about the same as what I would have spent on regular lithium AA's.
