EnerSys’ DataSafe Battery line consists of lead-acid valve regulated batteries. EnerSys DataSafe NPX batteries are perfect for high rate discharge UPS applications. The NPX battery provides up to 50% more wattage compared to conventional batteries with a 30% reduction in size. These batteries comply with the non-spillable battery regulation, therefore they can be operated in any position without leakage. The DatasSafe NPX battery series has a life expectancy between 3-5 years when kept at the correct temperature.

  • Sealed Construction: Can be operated in any position without leakage.
  • Complies with non-spillable battery regulation.
