Need an opinion.
In June I bought a pack of sixteen US125's. (6v. deep-cycle) I now have 700
miles on the pack. I use a PFC20 for charging.
I have questions about two of the batteries and would like an opinion as to
whether I should ask for a replacement of them. (I don't want to "forget
about it" and later wish I had, but on the other hand, I don't want to look
like an idiot, either.)
After normal charging and a twelve hour rest, here are the voltages:
BAT VOLT DEV.
#1 6.63 +.02
#2 6.55 -.06 LOW
#3 6.61 0
#4 6.63 +.02
#5 6.64 +.03
#6 6.62 +.01
#7 6.59 -.02 TERMINAL LEAKING
#8 6.62 +.01
#9 6.61 0
#10 6.60 -.01
#11 6.59 -.02
#12 6.61 0
#13 6.60 -.01
#14 6.60 -.01
#15 6.62 +.01
#16 6.62 +.02
I don't think there is any question about #7.
#2 had always been low. I've done an individual charge on it and it back
comes up, but after the next drive/charge cycle, it's back down again. Is
the enough of a problem to request a new battery? (I don't want to look like
an idiot, if this is in normal parameters.)
