Introduction

AA (and AAA) batteries power EVERYTHING. Portable radios, portable game systems, flashlights, remotes, toys, toys ( ͡° ͜ʖ ͡°), and, well, practically everything! However, these guys never last, and while cheap, the price stacks up over time. Yes, you can go with rechargables, but they literally cost AT LEAST 3 times as much. What if I told you that you can turn any battery into a rechargeable for free? Crazy, right? Well, actually, not so much.

Tools

Parts

Can be any combination of AAA or AA batteries. You need at least 2. Make sure they have as little charge as possible to avoid leakage. Any type of dry AA/AAA battery will work, such as NiMH, NiZN, MiCD, etc.

They may leak if they are not completely dead, but you can just scratch the residue away with your finger or a flathead.

  • They won't explode. and only get slightly warm, but you might want to charge them in a safe space.

  • Plug it into the wall. the LED should come on. Wait until the LED changes or goes off.

  • It should take 8-12 hours (on a cheap charger. Don't risk your expensive one). This is normal, as this is how long normal rechargables take.

These guys won't last as long as normal rechargables, but they cost way less!

Conclusion

Some of the battery's "fuel" may leak out. You just need to scrape it off the charger. Remember, only use dead batteries, and while it won't explode or catch fire, it's best to be safe and not charge it over carpet or flammables.
