Hi

I just topped up my  2x12 cell  Forklift battery  a few days back

I did  wait  a bit too long   so needed 30 l   and   the lead plates were exposed  about 2.5 cm (1 Inch  Grin)

After  filling up , i noticed , that the battery took a lot more AH  to reach full Volt (charge)

But  on the other-hand   ,   it seems  that capacity has not increased  Tongue     

I know that  that electrolyte is slightly heavier than water    ,  i guess i have to equalize charge the battery to mix   , after  filling as well  bike

Any others  having strange behavior  after topping up ?

Tankx

I topped up a friends system last Sunday that needed a similar amount due to a charge controller failing. Usually they take a couple of liters every fortnight but on this occasion it was almost 25 Shocked The voltage dropped from over 30 to 28.9 as soon as they'd had their drink.

Ok ,   sounds familiar  then

I guess i have to activate my generator , the first time of the year    to help the PV  for  an equalizing charge
