EnerSys Genesis NP33-12

EnerSys Genesis NP33-12The EnerSys Genesis NP33-12 battery features heavy duty thick lead calcium grids for years of dependable performance. The high energy density design, factory sealed case and leak proof construction ensures that these rechargeable sealed lead acid batteries are extremely reliable and virtually maintenance-free.

With an expected life span of three to five years in float applications at 77°F (25°C) ambient temperature, the NP series has more than 1,000 discharge/recharge cycles depending on the DoD for each cycle. The internal grid design has been perfected over 10 decades of battery experience to yield a battery that can recover even after repeated deep discharges.
