I seem to have a problem with my batteries
and getting them charged. and I hope someone can give some advice
I have a victron multiplus 110v connected to a bank of lifeline agm's with 660ah capacity.
Currently when I connect to shore power
or charge off the engine
for that matter, the batteries
reach around 13.80v in bulk in around 10 minutes, then the charger
drops into absorption and the current
tapers off into float volatage in around an hour. The current
then sits around 3 amps trickle charging
. On todays cycle, Im now at 87% charge with a 90Ah deficit.
I have connected to VE configure and followed Victrons settings videos but it makes no difference to the charging
The settings I have are:
State of charge when bulk finished 85%
Absorption voltage 14.27v (its hot here and I took this number from the Lifeline manual)
Float voltage 13.25
Charge current 100A.
As the charger
is not reaching any of these voltages should I assume that its just the batteries dying, or have I missed somthing obvious. And even though I cant seem to get them up to a full charge, can I try to condition them (following the lifeline manual) or will this irreperably damage the batteries?
