Hello Everyone,
I purchased a 12volts Flooded Lead Acid Battery last month having 140Mah capacity and installed in my off grid solar system, a brief overview of which is here,
1) MPPT Solar Charge Controller 80A
2) 3 X 180watt Solar Panel & 1 X 330 watt Solar panel connected in Series
3) Pure sivewave Inverter 1500 watts
The manual came with the battery suggested Cutoff Voltage setting of 14.4 volts and low voltage cuttoff of 11.5 volts. But I set cutoff voltage of 14.1 volts in the SCC and discharged battery upto 11.6 volts. After a month of use I notice decline in backup time so checked the Specific gravity which came out to be 1200 which is low as per standard. Now what should I do to get back the normal Specific Gravity of 1250 .
Thanks in Advance
