1. 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.
2. Good Discharging Ability
Tight assembly technology ensures an excellent high-rate discharge performance.
3. Long Service Life
A unique corrosion-resistant grid alloy ensures Prostar batteries have long service life.
4. Low Self Discharge 
Using high purity raw materials ensures Prostar batteries have less self-discharge.
5. Environmental & Non-polluting
Gas Recombination technology ensures the battery high seal reacting rate,which can prevent the acid fog from separating out.

1. Maintenance-free: advanced VRLA technology and absorption glass fiber separator to save the trouble adding electrolyte within usage life.
2. Leak tightness: unique structure design and sealing technology to guarantee no electrolyte leak regardless of chargers position. 
3. No memory effect: the capacity of some batteries like NI-CD is to reduce as a result of repeated usages, namely memory effect, while battery has no such deficiency. 
4. Low self discharge: Battery adopts special lead-calcium alloy slab lattice control to reduce battery self discharge to its minimum level to save trouble re-charging in long-time use. 
5. Long life: special material slab lattice and electrolyte added by high polymer material to expand the life span of the  battery
6. Wide range of suitable temperature.
7. Safe: low pressure air vent valve system to avoid excess gas producing inside the battery to guarantee normal usage life.
