Main Characteristic :

♦ maintenance-Free Operation

Absorbent glass mat (AGM) technology ensures efficient gas recombination up to 99% and freedom from electrolyte maintenance.During the expected float service life of Prostar batteries,no need to check the specific gravity of the electrolyte or add water.

♦ Good Discharging Ability

Tight assembly technology ensures an excellent high-rate discharge performance.

♦ Long Service Life

A unique corrosion-resistant grid alloy ensures Prostar batteries have long service life.

♦ Low Self Discharge

Using high purity raw materials ensures Prostar batteries have less self-discharge.

♦ Environmental & Non-polluting

Gas Recombination technology ensures the battery high seal reacting rate,which can prevent the acid fog from separating out.
