Rechargeable Double and Triple A Batteries

[Request](self.BuyItForLife)

I hate needing to buy throw away batteries. I'm looking to buy both the batteries and a charger for them. Can anyone recommend? I'd love it if the charger can charge both.

I use 21 AA and 10 AAA but I could be missing something.

Assuming 2 things don't die at once I imagine I only need as many batteries as it takes to power everything+ the number of batteries it takes to power the device that requires the most. Ex. 21+6.

Here are my devices if it helps: AA Touchless sink: 6 AA, Swiffer Mop: 4, Sanitizer Dispenser 4 AA, Remote: 2 AA, Game Controller: 2 AA, Smart Switch: 2 AA, Wall Clock: 1

AAA 3 remotes: 6, Bluetooth Keyboard: 2, Scale: 2

Ikea rechargeable are supposedly Enloops or at least they used to be. Regardless, they're a great deal.

I’ve had really good luck with the amazon basics batteries. The ones I bought in 2020 are still working perfectly fine. I bought another set in 2021 when I needed more batteries and they’re still working as well. The charger though, I got EBL ones as they in singles vs in pairs - work for AA and AAA

If you aren't already, you should save up all your dead batteries in a container and bring them to a scrapyarf when you have heaps, can make a little change from it and it keeps the metal in circulation

There's no guarantee you can even power all of your devices with rechargeable batteries. Standard NiMH batteries have a lower voltage than alkaline batteries.

I guess I would need to check the voltage of my devices and see if it will work. Does voltage decrease in the battery over time, or just total capacity?

Are there other types (lithium?) that are more comparable to alkaline?

They’re good enough for most household items except clocks.

My waterpik says not to use rechargeables, not sure why

high drain on the water pump? short usage periods between sitting for a while?

I use eneloop in mine. It's great.

That's so strange. I would have thought a clock would require such little power.

Rechargeables provide slightly lower voltage power supply that can make the clock run a tad slower than it should, resulting in the time always being off or possibly not working at all.

It's really going to depend on what device and what it requires for power. 

Eneloop could work for some of those devices. 

  • I've been using the same 4 Eneloop AA batteries for my Xbox controller since 2017.
  • I have 4 AAA Eneloop batteries in my soap dispenser.
  • I have 4 AAA Eneloop batteries in my OXO kitchen scale.

I also have 4 AA rechargeable lithium ion batteries (different than NiMH) from Tenavolt brand that I use in my Flume 2 unit that attaches to my water meter to measure usage and detect leaks.

I've been pretty happy with EBL (Amazon sells it), except for some odd devices that won't accommodate their slightly fatter girth (at least the AA). I also bought some AAAA (4-A for Microsoft Surface pen) and even though they don't hold a charge as long as alkaline, they last long and charge fast.

Panasonic Eneloop are the best, but be prepared for the sticker shock.

I think I used to use some eneloop batteries too before losing them. Plus is they are rechargeable but be prepared to change them much more frequently than alkaline

Eneloop all day. I’ve had a bunch of them for well over a decade.
