Description

The Mastervolt AGM 12/90 (group 31) is a 12 volt, 90Ah absorbed glass mat battery for marine and mobile electrical systems. In an AGM battery the electrolyte is largely absorbed in glass fibre, so the battery is completely maintenance-free and produces no gas under normal use. Its sealed construction allows installation in almost any position and makes it a straightforward upgrade from a conventional flooded lead-acid battery.

The construction gives very fast discharge at high currents, so the AGM 12/90 offers the same initial power surge as a 180Ah flooded lead-acid battery and delivers an excellent starter function, while also handling medium cyclic use. Glass-fibre technology keeps internal resistance low and thicker plates help extend service life. The poles unscrew so the battery works with every standard Mastervolt terminal, and it carries a two year warranty.
