EnerSys DataSafe NPX-25 Batteries

EnerSys DataSafe NPX-25 valve regulated lead-acid 12 volt batteries are designed for high rate discharge applications. These batteries are used primarily where high wattage is required for a short duration. With 50% more wattage available and a 30% reduction in size over conventional batteries, DataSafe NPX-25 batteries offer a superior value, especially in UPS applications.
