Our 2V OPzS stationary batteries are vented tubular plate lead-acid cells built to DIN standards. The flooded design delivers excellent capacity performance at high temperatures and on unstable power networks, with only low-level maintenance required across over 15 years of floating design life.

The series covers 2V 200Ah, 500Ah, 1000Ah, 1500Ah up to 3000Ah models. Cells are series-connected to build 48V or higher battery banks for solar power stations, UPS systems and telecom sites - and unlike sealed OPzV cells, the vented construction allows electrolyte topping-up for on-site servicing.

As a China storage battery manufacturer, we supply the full OPzS range at factory-direct wholesale prices, with OEM branding available for volume orders.
