Charging the US Powersports USX16. Do not leave your AGM battery on trickle charge all the time unless you’re using one of our trickle chargers designed specifically for AGM batteries, take it off now and then to let the battery slightly discharge but never less than 12.2v otherwise it will ruin the battery and shorten its life. Your battery comes to you pre-conditioned ready to install out of the box. You don’t have to add acid, however due to storage variations in the supply chain you should always put the battery on an AGM type charger prior to fitting. Draining a battery from parasitic loads is the number one cause of battery failure and once taken under 8V it’s very difficult for the battery to recover. Many bike owners just don’t realise about the onslaught a modern battery now faces in the realm of sophisticated electronics. We recommend one of our chargers as they are all suited for AGM batteries, this will ensure your battery is kept in the fully charged state it was designed for. We Post out FREE of Charge on a fully trackable postal service within the UK.
