Long Service Life
The grid and alloy are made as per special formula, therefore they effectively protect counter electrode against corrosion; the battery has a long service life due to good performance in high-current discharge, quick and reliable recharging and strong recovery capability after depth discharge. Battery life: 3~5 years for battery under 28AH;5~8 years for battery under 28AH.

Maintenance-Free Design
The hermetically-sealed construction protects the battery against battery leakage, acid fog, and corrosion. The gas generated during recharging can be absorbed and transformed into electrolyte, therefore, there is no need to add water, replenish electrolyte or measure electrolyte specific gravity.

Little Self Discharge Current
The battery is made of high-purity materials; therefore there is quite little self discharge current. The capacity loss due to self discharge is less than 3% per month, in which sense, it helps to reduce maintenance work load for user.
 

Wide Temperature Range
The battery maintains normal operation within temperature range from -20℃ to 50℃, and it has lower internal resistance in comparison with ordinary battery. It supports high-current discharge within the temperature range from -20℃ to 50℃, and the output power is higher than traditional vented battery.
 

High Consistency
The battery adopts advanced technology and undergoes 100% inspections regarding air tightness, voltage, capacity and safety, which ensure mass-produced batteries have consistent quality and performance. The battery is especially applicable to the cases which require series connection of multiple batteries, e.g. used as UPS backup battery and inverter backup battery, etc.
 

The battery adopts latest international design regarding the pole and compact structure, therefore, it is easy to install or take down, and it helps to reduce maintenance cost.
