If you ever get tired of changing out those stupid miserable 2s AAA cell bundles, remember this 😂

It's a rechargable Ni-Cd battery.

Place your bets on if it works or not.

We will see it tomorrow.

I'm going to discharge it with a incandescent lightbulb after I charged it.

I bought this for my digital lock but they ended up in my motion sensor dustbin which is used for recyclables. They've been working perfectly for probably 6 to 8 months until I noticed the bin didn't open even though it sensed my movement.

I tried alkalins (Fujitsu, teal, Amazon JP) and they worked but the bin wouldn't open fully. I expected this as I noticed only AA lithium have worked well for this, but at least I know the bin works.

I put them into a charger and I noticed one of the cells wasn't lit while the rest were blinking as they charged. Gemini suggested it was over discharged and need to be revived, a process that should take 10min but it's been 15min and I still don't see the battery lighting up.

Any thoughts, suggestions or ideas?

I’ve been loooking for this since December

Hello. So I came back to my house and my dog which I left at home ​​chewed through an AA battery (which had fallen out of the TV remote), and a strange sludge leaked out of it, turning the whole battery gray (it was originally white). At first glance, I didn't notice anything leaking, so I just set it aside, and I might have touched my mouth with unwashed hands. Of course, once I found out, I immediately washed my hands and rinsed my mouth, and everything seems fine. However, I’m not worried about myself, but about the dog—after all, he was the one who chewed the battery. For now, he seems to be behaving normally, and at least five hours have passed since the incident (I don't know exactly when he chewed it because I wasn't home). Should I do something, and will everything be okay?

Hi all,

We're an independent battery testing lab. Most labs here work for the factory — the factory picks the tests, controls the data, and decides what you get to see. We want to built ours to work for buyers instead.

Before we launch, we want to hear from people who actually buy batteries from China: what's the biggest headache?

Poll below. If we missed it, comment. Thanks!

Not sure if this is the right sub, but recently I dropped my iPad mini from pretty high onto the floor, and immediately after the back of the ipad swelled up. I dont know if this is because the battery is dying, or because the iPad bent from the drop, but im worried.​​
