Marine Power Solution

The BatteryJack inc. AGM1275F2-22 is a 12V 7.5AH sealed lead acid battery built with advanced AGM technology. It arrives ready to install and operates maintenance free across a wide range of marine electronics and consumer applications.

Replaces Conventional Wet Cells

This unit upgrades from traditional flooded batteries that require water topping and upright mounting only. The sealed AGM design eliminates acid spill risk and allows installation in any orientation, making the switch worthwhile when reliability and mounting flexibility are priorities.

Sustained Load Behaviour

Under continuous discharge the AGM construction delivers stable voltage output without the rapid fade seen in standard SLA types. The sealed recombination cycle minimises gassing during prolonged use, supporting consistent performance for fish finders, security systems and solar storage over the 2 year warranty period.
