Questions buyers ask about the Ritar RA12-200A
Any tips for keeping a spare battery?
Yes, but all batteries self-discharge slowly. Check the voltage every few months and recharge if needed.
Dimensions and weight of this model?
At 522 × 240 × 224 mm, measure the tray or compartment carefully. Plan the lift too: 55.5 kg is heavier than it looks.
AGM: how it works
Many glass-mat designs tolerate sideways mounting, as long as the maker says so. Motorcycles benefit from glass-mat batteries because they tolerate lean angles and vibration. A full charge now and then helps an AGM battery that mostly works part-charged.
