  • Advanced AGM technology prevents electrolyte leakage
  • Sealed non-spillable design operates safely in any position
  • Gas recombination system extends service life
  • Maintenance-free operation requires no water checks

Direct OEM replacement for Genesis NPW45-12

This 12V 9Ah sealed lead-acid battery fits UPS units that specify the Genesis NPW45-12 or NPW 45-12 model. It uses AGM technology for maintenance-free operation and a 4-7 year expected service life in float applications. The case is classified as non-spillable for safe handling.

Check terminal layout and case dimensions

Verify that your UPS requires a 12V 9Ah block with the same terminal style and physical footprint as the original Genesis unit. Polarity orientation and connector type must match exactly for a secure fit. The battery is designed for upright or side mounting without electrolyte leakage.

Sealed AGM construction prevents leaks

Absorptive Glass Mat separators hold electrolyte in place and recombine over 90% of gas generated during normal use. No water topping or specific-gravity checks are needed throughout the service life. The rugged case meets IATA non-spillable standards for transport and daily operation.

Questions about this item

Does the NPW45-12 arrive ready to install or do I need to add acid?

Should I choose the NPW45-12 or a higher-capacity model for my UPS?

The NPW45-12 is a 12 V 9 Ah unit; only select it if your UPS specifies that exact voltage and capacity.

What runtime can I expect from the 9 Ah rating in my UPS?

The 9 Ah figure is the rated capacity; actual runtime depends on your UPS load and the 4–7 year design life.
