What does the abbreviations MF, GEL and AGM stand for?
MF stands for Maintenance free. A maintenance free battery is a sealed battery which you do not have to refill with fluid after use. MF batteries need, like every other battery, maintenance charging to provide the longest service life possible. In a GEL battery, the sulphuric acid is bound in gel/solid form to decrease the risk of leakage and fluid losses. AGM stands for Absorbent Glass Mat. In an AGM battery the electrolyte is absorbed in a glass fibre mat. AGM is a perfect starter battery. Because of the enhanced acid density within an AGM battery it needs charging with a higher current.
