Never charge a sealed bike battery on a car charger, they push too much current through them causing overheating and shortening their life. Buy the best bike charger you can afford and always charge every 3-4 weeks when the bike is not being used.[/QUOTE]



I have a Battery Minder which supposedly keeps the battery charged and has a maintenance mode that cleans the plates. I actually used the Battery Minder to charge the new Yuasa before sealing it.

thanks for the comprehensive explanation and diagnosis procedures.
