Hey all, so I've got some weird Nc batteries which are basically 3 D cell batteries sealed in a tube with this info: "SEALED Rechargeable batteries, 3,6v 1500mAh. NI-Cd"
I'm wondering, since I have about 2-3 of these, (the hyphen will be explained later) is it a good idea to try and use these? Or are they so old and useless that I would be better off just buying lithium ion batteries?
Apparently they've worked before guaranteed but one of them has since had its seal broken (hence, the mentioning of 2-3 and not just 3) . like a tiny crack on the plastic part around the 3 cells connected in parallel. I read online that the electrolytes could leak out but I'm not sure if it's from the batteries themselves or just anywhere in the seal since I'm not too fond of batteries yet. But that's the whole reason I'm asking this, a little learning experience at the least, or some new usable batteries for future projects in the future.
Now if you are someone reading this who already knows these batteries aren't worth the time I'd really appreciate if you just skipped the rest of this post and tell me to throw them away. Otherwise I'll never really find out until it's too late. Thanks.
Now for charging them? I don't have a fancy shmancy battery charger with adjustable voltage and digital compliments. I want to make one my own, just because.
I have 3 wall chargers with varying outputs I'll list here.
Note: warning on the thing says; polarity restricted. Designed for use with DSL or DSi only.
it also has two prongs, they both look like variants of the usb family.
Output: 5.2V 450mAh Second output: 5V 600mAh
Output: 12V 1.25mAh
Output: 5V 700mAh (my guess is this is the best option)
I'm looking to cut one of these open and slap them onto a breadboard with resistors and such, but can't decide which is best to convert. I tried looking online but there isn't much info about these types of batteries.
Anyways thanks to all those who read this far at least. Hope someone can help me out with this fun little project. And have a great day!
