I have a double bank (2 x 3) 105 a/h 12 Volt GEL type batteries
that were left on a boat on the hard
, the batteries were "in circuit"
being charged/topped up by a 110 W Solar
protected by a solar
to prevent "over-charging"
This system had been working for nearly two years
while the boat was in storage
just operating a small 12 V fan to ensure air circulation
and a bilge pump
to take out any rainwater that managed to get in
not sure yet what happened,
maybe a lightning
strike knocking out some fuses
maybe the solar panels
or the regulator
faulty - not sure
but leaving me with 6 x 105 A/hrs batteries totally discharged
My first concern is getting these batteries recharged
which I intend to do with an industrial
heavy duty battery charger on shore power
Has anyone had experience of doing this
is there a particular procedure to follow to minimise possible damage
to the GEL batteries, ?
from what I gather
they have been discharged or discharging
for maybe 5-6 weeks ...
Thanks - John
