Look after it.
The following is not in any particular order.
Do not overcharge.
do not over discharge.
Do not leave it in a discharged state.
Keep it at room temperature as excess heat or cold shortens the life of a battery.
Check the electrolyte level and do not let it get too low or overfill it.
Charge and discharge it at the C20 rate
Radiant charge it to desulphate the plates and reduce dendrite formation.
Check the specific gravity when the battery is charged fully as this will show if there is a problem and adjust id required.
Keep it clean as dirt and moisture can cause the battery to discharge.
Seems I have violated most of these in my move from another town.
What can I do to save these batteries Mik?
LMK soon, I have some time off and need to get them going again.
