Hi Ron,
It has been my experience when sulfated batteries are pushed you do get higher
gassing and a higher "hit you in the face" smell off the batteries. Keep the
room well vented and watch the temp (max 125F).

Just a follow-up on this. I have able to get the batteries to accept a
higher and higher amp charge and the hydrometer indicates recovery is
taking place. However, in the last 15 hour session of charging (this
is being done in an unmonitored location overnight) the batteries off-
gassed quit
Some interesting things to consider, thanks everyone!

Hi Ron,
Given the time in "storage" the cells will be severely sulfated and will not
accept much current initially - probably 28A max (1400x2%) and 70A (1400x5%)
will suffice once current is accepted. A standalone "unregulated" charger or
constant current would be best to reclaim these or at

Ron,
I had a similar experience.
Customer had a similar battery, industrial, 1200 amp hrs at 48v, IBE that sat
for a few years.
I hooked them up to a dual stack outback, and just turned it on. The voltage
was brought up with some solar and then we ran the generator for a few days
straight.
Ron,
Before hitting them with a lot of current, I'd put groups of six on a
lower charge with an external charger for a while. It'll give you a
chance to see how each one is doing. Then re-wire them for 24-volts
and connect the Outback inverter. If they are to come back to life
they'll need
I have just acquired a 24v set of 1400a/h 2v cells that have been in
storage without a charge for several years. They were connected up in
a system that was never turned on (long story). I believe these
batteries can be recovered if I can get a high enough amp charge into
them. The battery
