  • AGM tech boosts capacity from 7.5Ah to 9.0Ah
  • 100% OEM compatible with Aqua Vu Marcum Vexilar
  • Sealed maintenance-free design prevents electrolyte leakage
  • Compact 5.94 x 2.56 x 3.66 inch form fits existing bays
  • Expected 4-7 year service life backs reliable backup power

Direct replacement battery

The PowerStar 12V 9.0Ah AGM battery replaces 7Ah or 7.5Ah units in Aqua Vu, Marcum and Vexilar devices. It uses sealed Absorptive Glass Mat construction to prevent electrolyte leakage in any orientation. The maintenance-free design offers an expected service life of four to seven years.

Capacity upgrade path

The 9.0Ah rating increases runtime over the original 7Ah or 7.5Ah cells without changing voltage or footprint. The jump is worthwhile when longer operation between charges is needed for fish finders, flashers or UPS units. No firmware or hardware changes are required to use the higher capacity.

Simple drop-in install

Terminals are T1/T2 type measuring 5.94 by 2.56 by 3.66 so they match the existing connectors and battery compartment. The sealed case allows mounting in any position without spill risk. The only common issue is forgetting to recycle the old lead-acid pack according to local regulations.

Questions about this item

What are the exact length, width and height dimensions so I can confirm the 12V 9.0Ah battery fits my device?

The battery measures 5.94 in length, 2.56 in width and 3.66 in height. Verify your compartment matches these figures before ordering.

Which terminal type does the battery use and what is the correct orientation when installing it?

It uses T1/T2 terminals. Insert the battery so the positive terminal aligns with the device's positive lead; reversing polarity will prevent operation.
