Here are most of the good batteries I took from soon-to-be recycled batteries from work, all dell laptop batteries:
They currently have charges ranging from 4.08v to 4.20v. One particular battery pack had all of them charged to 4.25v so I drained all of them a bit and charged them back up to a more reasonable and longer lasting 4.16v on average with this charger (of course they lose a bit of of that over time.)
Charged w/ my xtar wp2 II (love it!). it’s been fun so far looking at the different brands that come with the different battery packs and their internal construction.
There is some severe weather coming our way, at least I’ll be able to light things up for awhile if need be.
Ah, very cool. If you have a DB you’ve collected that’s one thing, but if there is a certain skill other than just googling the identification, please let me know. I actually started a new thread to be more specific. Thanks!
Ah, so my Fandyfire HD2011 (if it ever gets here, damn back order) is said to draw 3.8 - 4.7a so I assume I’m covered. Thanks very much for the info. If I uncover any other battery types during my travels, I’ll certainly let you know.
Those numbers are based on new batteries. The only way is to check capacity and draw amperage on each used cell. Voltage or the ability to hold voltage has nada to do with either. But one piece of advise is NOT to mix cells from different packs. Generally cells from the same pack are matched but without knowing capacity or condition of used cells a guess at best. This is just friendly knowledge, do as you please.
