The ways & means to increase the life and performance of Lead-acid Batteries

The most important part is the care during initial filling and charging which determines the life & performance and knowledge about how a lead-acid battery works.

Acid Filling Procedure:

The battery physically for any damages/visible cracks and cleaned prior to filling of acid. Check the sp. Gravity of acid of all the jerry cans corrected to 27ºc prior to filling. Pour cool dilute battery grade sulphuric acid 0f 1.220/1.190 sp. Gravity up to the max. level by ‘acifil pump’

Initial filling & charging (IFC)

The battery room should be clean, dry & cool, with proper lighting & ventilation. Batteries to be cleaned before initial filling. Matching constant current charger, should be available capable to supply requisite volt & amps designed to give at 6% rate of charge up to 2.75 VPC at toc voltage

Polarity check & Rest period Procedure:

Just after acid filling, to check polarity of the cells by checking the voltage of all the cells, if any cell wrongly reverses assembled. The voltage observed is not that important at this point. Also check for any leakage visible after filling

Allow 12 hours rest for the cooling; allow the plates & separators to soak acid, but not more than 24 hours. Top up again with acid, same as filling- in sp. Gravity.
