BUMP - Rechargeable AAA Batteries with Charger Cable - 1.5V Fast USB-C AAA Lithium Batteries with LED Indicator - Long-Lasting and Eco-Friendly Power Solution for Remotes, Toys, and Keyboards (4-Pack)

I had an issue where one battery did NOt take a charge. The seller sent me a replacement set, and also a newer version of the batteries. So that is why I stated even better seller... if I could give 50 stars I would.

Great rechargeable AAA batteries with strong, consistent power output. The fast USB-C charging is a major convenience, and they hold a charge well. A reliable, cost-effective upgrade.

Don't get me wrong, I like them, and I use them often. It certainly saves money to be able to recharge. They just die much sooner than normal AAA batteries. I use them exclusively for my personal and loaner sets of Walker Razor ear muffs. Just more convenient to have dedicated recharable batteries in the range bag. They last for any given trip, but if I leave them on by accident they are dead the very next day. I haven't felt like timing the exact life, but it must be somewhere between 8-24 hours and with a pair of Duracells a set of Razors lasts 40+ hours. With that said, I would still buy them again. Just know that whatever your purpose, you will be removing them for a recharge at least twice as often as you would replace non-rechargeable batteries. This is probably a non-issue in most circumstances.

These are Li-Ion batteries with a voltage regulator, so they deliver 1.5 volts. Can replace alkalines in things like clocks and remote controls where NiMh batteries don't work properly. Each one has a USB-C port for charging, and there is a one-to-four USB-A cable provided. Disposable batteries are obsolete.

Update Oct 1 2024 Last night I woke up to this almost burning my home down I have only had this for two years and it exploded last night. Around 2 am I was woke up by the smell of something burning I found out really quick what it was when I burnt my hand by touching the two Aaa batteries I took out of my fire stick remote to charge about 11 pm. The USBC batteries are dangerous. The Micro USB batteries I have had for a year longer is still working amazingly but you can be sure I will only charge them while I am home from now on. Previous post……in 2022 This is absolutely amazing for my Roku remote and also my thermostat in my RV 10 out of 10 recommend I’m probably going to get more they work like a dream. I have had them for three months and had to charge them once.

FYI, I ordered these batteries on 1/25/23 and all 4 were dead/wouldn't recharge by 11/1/23. I used two of the four almost constantly for a low energy device and then switched to the other two. That means, if I had used all four at the same time, the life expectancy would have been cut in half from 9 months to 4.5 months. That doesn't seem very good to me for around $25, but this is my first experience with rechargeable batteries so I'm not sure. BTW, two batteries in the device would last about two weeks between charges. UPDATE: I prefer rechargeable batteries because of the environmental issues with others, so even though I wasn't completely satisfied I reordered. Two of the first set wouldn't charge at all so I sent them back. I've had the second set for 8 weeks and they're already only holding a charge for a few days. I've been using them for the same low energy device throughout all of the batteries so it's a very fair comparison. In my experience, it seems the quality of this product is going down.

I just needed a few batteries for a timer, my Roku, remote, and my old TI 84+ silver edition calculator. I bought four AAA‘s at the end of 2022 and bought a combo pack of AA/AAA in February of 2024. I like that this is an all-in-one solution. It comes with the charger that will plug in adjust about anything -Computer, phone adapter, charging port in a car or airplane seat. I know there are probably batteries that are rated much better, but I’ve not had any issues with these. I didn’t want to spend $$ on a big rechargeable setup. I will note that they don’t support pass-through charging - meaning you can’t plug them in while they’re in a device. They’re not advertised as being able to do this, but I tried anyway. 5/5. Fair price, and no issues after 18 months!

We bought, in 2022, a few of these in AAA and replaced a bunch of alks in the house. The batteries hold a charge and recharge quickly. Very convenient. Now 2 years later, within a few weeks all of them stopped (staying red and not taking a charge) and have been replaced. It's definitely not thousands of recharges, but I am still giving this a five because they were very good batteries for two years and they were very inexpensive to start with.
