I have a Honda Activa 2007 model. The battery fitted in it is electrolyte topup battery which requires distilled water to be filled up from time to time. My question is can a maintenance free battery be fitted in place of an electrolyte battery?
Yes, I've made this swap myself on one of my bikes. You just need to make sure that the maximum current (sometimes referred to as 'cold cranking amperage') and Ah ratings are at least as much as the old battery. It doesn't matter if the new battery has higher Ah or current ratings, that won't cause any harm.
