SKU CH-DRVJ-X2R1H

12V 2.3AH SLA battery with AGM technology provides maintenance-free, leak-proof power for UPS units, replacing DMU12-3 and VEC15 models with a 4–7 year expected life

  • 12 V 2.3 Ah SLA battery powers UPS units reliably
  • Advanced AGM technology enables maintenance-free operation
  • Sealed construction prevents electrolyte leakage in any position
  • Gas recombination system recycles over 90 % of generated gas
  • Expected service life of 4 to 7 years under float conditions

Product Identity

This 12V 2.3AH sealed lead-acid battery replaces the DMU12-3 and VEC15 models in UPS units. It suits administrators who need a direct drop-in unit for backup power systems.

Upgrade Context

It replaces aging cells that no longer hold a full charge after several years of float service. The jump is worthwhile when runtime has dropped below acceptable levels or when the original battery reaches the end of its 4-7 year design life.

Installation Notes

The maintenance-free AGM construction allows mounting in any orientation without electrolyte leakage. Gas recombination exceeds 90% during normal use, so no venting or water topping is required. Ensure terminal polarity matches the original before connecting.
