While I'm charging that most negative cell group, I decided to test 4-cell groups with a 55w bulb..
P.S. I started all groups at 3.6xV
Took surface charge off so each cell read 3.3xV
Recorded amp pull at 4.25a (.3c) (V-below is 10 min into draw)
Cell groups 1-4 voltages during amp pull...
1.) 3.27v
2.) 2.95v <--- Ick!
3.) 3.28v
4.) 2.90v <--- Double Ick!
Groups 2 and 4 at no greater than .3C and their voltages are that low...
So far, not looking good...
I will check every so often and see which group craps out first..
EDIT AS OF 1:48am...
Welp, 1.5 hours in and cell group 4 starting dropping with cell group 2 right behind it.. (within minutes)
Cell groups 1 and 3 kept their 3.2xV While this happened..
So we are looking at about 6.5Ah for groups 2 & 4...
Onto next 4 groups...
EDIT AS OF 2:01am
Cell groups 5-8 (Again V's read 10 min in)
5.) 3.00v <---- Not happy
6.) 3.29v <----
THAT'S what they should all read!
7.) 3.29v <---- Yey!
8.) 3.01v <---- Again "not happy"
These groups will be my last for tonight, as I need SOME sleep
EDIT AS OF 4:10am
Ok final data on this second group..
Cell groups 5 & 8 started dropping at pretty much the exact same time..
(till they hit my self enforced 2.6v under load threshold.)
About 2 hrs and 20 min in.. So for groups 5 and 8 we're looking at about 9.9-10Ah.
