Lifepo4 AA and Aaa batteries

[Bliksis]

Do we get rechargeable Lifepo4 AA and Aaa batteries that can be used in remotes, computer mouse, etc?

I did a quick search on TakeAlot, but nothing pops up.

I also wonder if it would make financial sense to buy these if it exists.

No straight replacement


AA cell voltage is 1.5 V
Li ion NMC cell voltage is 3.7 V

LiFeO4 is not available in smaller form factors

The NMH rechargeables are a waste of money.

I found it better just to buy good quality carbon batteries

Yeah it's like I thought as well. Thanks!

Energizer Ultimate Lithium works really well, expensive but last way longer than normal cells.

Why do you say NMH are a waste of money? I used them in my remotes and Xbox controllers and can't say that they are worse than non-rechargeables.

What device would you use these in?

backup in test equipment .but you can take a normal remote and remove the one wire from the negative of the second battery and relocate it to the bottom plate and voila you have a lith remote on one battery ,that charges on an 18650 charger in like 10 minutes so youre never without your remote .they are so much better than crappy 1.2 volt ni-mh that vrek in the cold and allways die when not expected .ni-mh are not recommended for lots of electronics, voltage is too low unless it made for them .but ni has its place and saves money .

Same - I power all of my flashes with rechargeables - currently mostly Uniross Hybrios but I do have a few Amazon Basics as well.

Hmm..might give the uniross a go. I see they have a AA to D adapter which will come in handy for my gas geyser ignitor which chows normal batts.

The 1.2v is the crap part

Have seen li-ion ones where they put a lipo pack in with a micro usb for charging and buck converter the get the 1.5v

Scarce

Guys I've used these for over a year now with no complaints! They're 1.5v and last long, and are easy to charge up again.
