AGM batteries are tried, tested, and beloved. The technology behind AGM batteries is mature and well-established, and they’ve been a reliable choice for many years thanks to their robust design and proven stamina. While an AGM battery contains lead acid, which makes it heavier than a lithium equivalent, it also comes with numerous advantages. The glass matt fibres that hold an AGM battery’s electrolytes prevents spills, and means that virtually no maintenance or upkeep is required. They’ll also operate happily in below-freezing temperatures. KickAss AGM batteries come in a range of amperages, and are available in both regular and slimline design, so they’re easy to install in tight spaces.
