Oh my god I posted last 3 days ago ? Feels like a week ago. By the way yall, while I was away, I now got 32 18650 batteries of varying capacities harvested primarily from laptops and a few powerbanks, 8 lithium-ion AA's, 8 NiMH AA and about 12 NiMH AAA's, all eneloops lol.
I now spent about more or less $200. I gotta stop self-funding my research cos I'm about to run out..
I've also been using the cardboard box my RTX 3060 came with, lol.
@cgervasi Right now I'm testing their capacities and I'm picking out ones with highest caps cos some of these are > 10 years old and prolly have never been charged in a while. I have fans and flashlights that use 18650's and it'd be cool to reuse some of the ones that're still working.
The rest I'll either stash away @ 3.6v and plan for what I wanna do with them. Dead ones I'll dispose of em responsibly. I've encountered ones that don't have a voltage at all, like 0V on my multimeter.
@cgervasi Initially I'll keep ones that are still working. I'll test them from time to time. If a year passes and I still dunno what to do with them, I'll prolly donate or dispose 'em responsibly as well cos some of the ones I have are < 1000 mAh. Safe to say I have more of quantity than quality, lol
As for NiMH ones, the 3A's have been used for motion sensing lights thing and remotes. I know these discharge faster than alkalines but I read eneloops have LSD's..
@cgervasi And if these run out of juice, I have a charger so it's gonna be fine
2A's, idk where to use them. Flashlights probably but we currently don't have one that's working and the ones we have use 18650's.
Lithium-ion AA's however, they're still new and I have yet to learn more about this thing. Honestly I only have surface knowledge of this hobby I'm on. I have so much more to learn but I'm running out of money lol. I may have overspent, but it's better to have 'em ready than have none.
I just now have more things to maintain now but it's alright.
I'mma be real, but it's better than doing nothing honestly cos when you don't have friends, and you go home from work or whereever else, you just have nothing else to do maybe besides gaming, sleep, or maintain my rig.
Idk. It's prolly a temporary thing but I think batteries are cool so I'm willing to learn about. I just wish I have enough cash to learn more and then actually build something cool with what I learned..
