tubular gel batteries

tubular gel batteries

OPzV 2-2000-Y Product Feature OPzV battery can offer 20+ years design life in float service at 25℃ and are more suitable for cyclic use under extreme operating conditions. Floating design life: 20 years at 25℃ Cycle life(2V): >2000 at 80% DOD and 6000 at 25% DOD Self-discharge rate: ≤2%/Month...

Product Details

Tubular gel batteries are used because they have the ability to be recycled many times. This means that they can go from being charged to being discharged to 50% numerous times without damaging the batteries unlike that of other batteries such as cranking batteries which are used to start vehicles.

The innovative Gel Technology does not only combines the advantages of lower internal resistance of OPzV battery , but also do have much  better thermal stability and longer cyclic life.
