Title: SCORE!!!!
Post by: Voodoochikin04 on December 22, 2009, 11:11:54 AM: so... since i do computers for a living, my buddy brought his computer into the shop to get fixed. I told him i would take it home and do it for free rather than charging 2hrs labor. so i take it home and fix it for him, and when he comes to pick it up he brings along this battery i have wanted to buy from him for awhile. what i knew about it was it is a dry cell. he bought it for his car stereo and shortly after got rid of his stereo and this battery has sat in his garage. he wanted 100$ for it previously. so he sets the battery down and says "here you can have this" fooking sweet!!!! its a stinger electronics sp800

my free battery!!!! (http://www.darvex.com/SP800/Stinger+800+Dry+Cell+Battery.html)

Post by: Voodoochikin04 on February 14, 2010, 12:24:14 PM: so the battery had 6volts charge to it.. i put it on the battery charger all day yesterday on 35amp fast charge, then i put it on 2amp trickle over night.. it had 11volts this morning, but holding the test on it, it will slowly count down the volts.. also it wont power anything other than an led flashlight.. whats the deal? battery shot?

Post by: Nutz4sand on February 14, 2010, 02:58:53 PM: Sounds like it.

I dunno if putting it on a 35 amp charger all day was the best idea either.

If I have a battery in question I like to ease them back up slowly. 2 or 6 amps maybe.

But maybe someone here know which is better?

Post by: Voodoochikin04 on February 14, 2010, 04:02:48 PM: just wasnt sure if i your supposed to use something other than regular charger for these dry cells or different procedure.

Post by: fabr on February 14, 2010, 04:43:35 PM: There are different charging procedures as such but IMO that battery is a goner. No battery will survive extended discharged times.
