SKU CH-90R4-YBC2T

A 12V 9.0Ah AGM sealed battery that fits UPS units and fish-finder brands, replacing 7.5Ah packs with more capacity

  • 0 Ah capacity exceeds standard 7.5 Ah replacements
  • Advanced AGM technology delivers maintenance-free sealed operation
  • Fits Aqua Vu, Marcum and Vexilar devices directly
  • 12 V 9.0 Ah AGM battery with T1/T2 terminals
  • Expected service life of four to seven years

Drop-in UPS battery upgrade

The PowerStar 9Ah 12V unit replaces standard 7Ah or 7.5Ah batteries in compatible UPS and backup devices. It fits equipment such as Aqua Vu, Marcum and Vexilar systems. Advanced AGM technology raises capacity without changing the footprint.

AGM sealed design limits

Absorptive Glass Mat construction absorbs electrolyte in glass-fibre separators, preventing leaks and allowing operation in any orientation. The battery is classified non-spillable and meets IATA transport requirements. Gas recombination keeps internal pressure stable during normal float service.

9.0 Ah capacity headroom

The 9.0 Ah rating delivers more runtime than the 7.5 Ah cells it replaces, extending backup time for connected loads. Expected service life spans 4 to 7 years under typical float conditions. Beyond that window, capacity fade will reduce available runtime and replacement is advised.

Questions about this item

Should I pick the 9.0Ah version or stay with a 7.5Ah battery?

The 9.0Ah model gives more capacity than a 7.5Ah unit while keeping the same 12V rating and dimensions, so it fits the same space and extends runtime.

What does the 9.0Ah rating actually deliver when the battery is installed in a UPS?

It stores 9.0 ampere-hours at 12V, providing longer backup time than lower-capacity cells and supporting the same load for a greater duration.

Which terminal standard does this battery use and what does it limit?

It uses T1/T2 terminals, which suit standard UPS and fish-finder connectors and prevent use with larger bolt-on lugs.
