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)

Great!

Great batteries that last a while in small appliances (computer mouse). I would recommend charging them all at once to avoid overheating a single battery. I did have an issue with one melting due to some unknown reason, but happened once and never again.

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.

The media could not be loaded. 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!

On the 2nd recharge attempt, the batteries started to smoke a one lost its charging tip. This is using the included charging cable and appropriate charger. I am so disappointed and feel ripped off... essentially $8 for two batteries with a one-time use. How many other of their batteries are compromised? If you read other reviews, I'm not alone. Buy at your own risk, or just buy regular name brand batteries... it'll be a lot cheaper.

First off, they are noticeably lighter than other AAA batteries. My issue with them is they don’t hold their charges long enough. I started using them in some camping LED lights for the weekend, but by the second night they were dimming and already going out.

So, I bought these specifically `cause I hate buying batteries and NiCad and NiMH batteries are so cumbersome to recharge. These were a pleasant surprise to be sure.To start. The AAA version I bought came in USB-C not the USB Micro that I was expecting. I love it. The charge indicators are built right into the + terminal. Discrete but perfectly visible.The Bump AAA are rated at 400 mAh vs the Energizer Power Plus Rechargeable listed at 700, but I would say that in my experience these charge faster and are easier to deal with.Energizer Max is closer to 1200 mAh so for that capacity there may be a different brand to look at if you want to stick with USB rechargable Lithium AAA batteries. For what I need, these will be perfect.The one thing I would point out, the USB connectors are a little off-set to the battery, which is a little confusing the first time you try to plug them in.

I've used a set of these for 4 months now. I am a service technician and I use these batteries exclusively in a small flashlight I carry on my belt. I use this light every day. A single charge will normally last a couple days. Maybe 4-6 hours of actual run time. I keep the charger in my truck. The light only uses one battery at a time so when I load the 4th battery in the light, I plug in the other 3 to charge. I never run out.Duracell batteries do last longer, but I've only spent $16 on batteries for the last 4 months. That's less than half of what I was spending before.I'm impressed with the performance. I've order a second set of these for my helper. I hope they will expand the line in future. I could use some AA and 9v
