12 V 7.5 Ah AGM marine battery

This sealed lead-acid battery delivers 12 volts and 7.5 amp-hours in a single pack. It uses advanced AGM technology for maintenance-free operation and is built for marine electronics such as fish finders.

Check terminal type and voltage match

Verify that your device accepts a 12 V supply and can connect to T1 or T2 terminals before ordering. Confirm the physical space available matches the battery footprint and that your charger suits sealed AGM chemistry.

Thermals noise and power draw

Sealed AGM construction produces no audible noise and minimal heat during normal discharge. The battery accepts charge current within standard AGM limits and holds voltage steadily under typical fish-finder loads.

Questions about this item

What comes in the box and do I need to buy cables or terminals separately?

The package contains one 12 V 7.5 Ah AGM battery measuring 5.94 by 2.56 by 3.66 inches with T1/T2 terminals. No extra cables or terminals are included.

The title lists 7 Ah, 7.5 Ah and 8 Ah — which capacity should I choose?

The battery supplied is the 7.5 Ah version; the other figures are cross-reference capacities for the models it replaces.

What does the 7.5 Ah rating mean when I run my fish finder?

A 7.5 Ah rating means the battery can deliver roughly 7.5 amps for one hour or a proportionally lower current for a longer time before needing recharge.
