Solar Storage Lead Acid Battery

 (1) Safety: no leakage on battery terminal, ensure using in safe and reliable

(2)   Maintenance free: due to all internal generated gas restore to water, do not need water replenishment

(3) Exhaust air system: it can exhaust excess gas and make air pressure up to normal range when battery overcharges and internal pressure is over high, this time safe valve will close by itself, so there will be not additional gas accumulate.

(4)  No free acid: special separator adsorb electrolyte, so there is no free acid inside battery, then battery can be installed in various position
