bumpAAA USB-C Rechargeable NiMH Batteries - 10 Pack - Sustainable & Cost-Effective Alternative to Lithium Ion - Fast Charging, Long-Lasting Power - Two Charger Cables Included

Easy way to recharge and you know they are recharged!!!

I enjoy these so much. It’s such a chore to remember batteries. Now I don’t have to, would recommend these to everyone

Products works well enough, make sure that you buy the correct voltage...

I started getting rid of all of the alkaline batteries in our house. The economics of constantly buying non-rechargeable batteries just doesn't make sense any more. The price of regular batteries keeps going up as most rechargeables stay the same or go down in price. It seems like the most common are AA and AAA for most items. So the more of those the better.This is a 10 pack with two USB charging cables that will charge four each. Hmmm, that sounds like "hotdog logic." Just like hotdogs coming 10 to a pack but the buns come 8 to a pack. So there's always two just lingering around I suppose. That is not a complaint because the more batteries the better. What is disappointing is the low 450mAh capacity on this batteries. Most lower cost AAA nimh are 600mAh and really good ones are 1100mAh. So I wouldn't use these in any high drain items for sure.Despite their lower rating, I have a ton of remote controls and small items that sip energy and use AAA so they should be fine for those items. They were fairly well charged out of the box and topped off very quickly. The top of the batteries glow Red when charging and turn Blue when finished.If these are for low drain items definitely look into getting them but had I needed these for high drain items, I believe I would've been disappointed. So for my use case, I got lucky. They're OK with some novel ideas and a bit better than just Meh. So 4 stars-ish.

We've used these for two important items in our household.The first is our automatic pepper grinder! These work for about a little over a month per pair in that before they need to be switched out to charge. That is great! The regular Duracell batteries from Walmart didn't last that long!The second is our Roku TV remote. I put two batteries in back in 2023, and they still have not needed to be changed out.They are durable and easy to stow on a shelf. Charge is a few hours.

One set would not charge. I changed them and used other c chargers and they still would not charge.

These AAA batteries have been a great choice instead of using non-rechargeable batteries. These cost way less and you get way more battery life.The batteries have been used in remotes, game controllers, garage door openers, toys, flashlights, and a couple other devices. They all fit perfectly and powered everything great.They charge easily and you can charge up (8) batteries at a time. This does not come with the charging adapter plug, just comes with the charging cords for the batteries. I will say, actually plugging the connector into each of the batteries is a bit difficult, but after several attempts figured out the way to get them to connect. Not a problem, but advise not forcing them in if you encounter resistance until you get the orientation down.I like these a lot and would recommend.

I love the concept for this product; I hate throwing away so many batteries a year, so rechargeable batteries are an amazing idea! I use batteries for flameless candles, because my lovable cat is too dumb to exist around a real candle. I have my candles set on a timer, and they come on every day and stay on for 6hrs. With regular batteries, I am replacing them every 2.5-3 months. With these rechargeable batteries, I have to replace them every four days! I wasn’t expecting the same longevity, but you should AT LEAST get one week out of them. Perhaps in a different application where they’re used far less often (like a tv remote) would make them last longer.My other complaint is that you get ten batteries, but two sets of charging cables with four USB-C chargers each, for a charging capacity of 8 at one time. I think it would make more sense to have two (heck, even one!) sets of five! Not a deal breaker, but annoying if I’m trying to charge them all at once.
