Easy maintenance
When battery is charging, hydrogen would be absorbed and reversed to eletolyle by plates. So it doesn't need to refill water and balanced charging, which makes maintenance easy.
Keep electrolyte high
Eletrolyte is absorbed in glass mat and still. Battery can be used or positioned under 90 degress angle orientation.
Extremely safe
When excessive gas production by inappropriate charging occurs, safety valves will automatically emit the gas to prevent battery cracked.
Low self-discharge
Special lead-calcium alloy plates makes lower self-discharge and longer preservation.
Long life, high economy
Plates are made of anti-corrosion lead-calcium alloy, which has longer float charging life. Separator(glass mat) can trap eletrolyte and active material on positive plates, prevent active material drop at the same time. More over, greater deep charge cycle lifespan makes battery worth to turst and high-economic.
Low resistance
Higher current, better performance.
