FAQ’s
How can the SOC(State Of Charge) of a Flooded Battery can be accurately
measured?
State Of Charge can be correctly measured by measuring the specific gravity ofthe
electrolyte with the help of an instrument called Hydrometer.
What is the Specific Gravity of a fully charged battery?
The SG for a fully charged battery is 1.255 (±0.01).
When should i top-up my flooded batteries?
Itisrecommended tocheck frequently yo ur battery for water loss. But ifthereisfrequent
cycling then in15 days o therwise on ce ina month the electrolyte level to be checked.
What type of water should be used for top-up?
The recommend ed water toping up should only bedone with DM(De Mineralized) water
which is available at battery sellers. No other form of water should be used as it may
contain excess mineral content which can contaminate the electrolyte leading to pre
mature failure of the battery
What is the proper electrolyte level
? The electrolyte level should be 1/8 inch below the bottom of vent
well. Doyoueveraddacidtobattery?
No, acid should never be added to the battery. Only distilled water orde mineralized water
may be used for top-up
What are the common mistakes made in flooded battery?
Undercharging- Leaving the battery in partial state ofcharge or storing the battery
in dischargedstateresultsin sulphationleadingtopre mature failure ofthebattery.
Overcharging - Continuous charging of the battery due to inverter problems leading
to excess corrosion of plates, excess water consumption and in turn damaging
the batteries
Under Watering - If the water level drops below the plates, it will get hard ened leading
to pre mature failure
Over Watering - Excess addition ofwater dilutes the electrolyte resulting in low battery
