Charging a motorcycle battery?

it all sounds good but you need a voltage monitor to actually know if a battery is charged or not ..full charge would read around 12.5 volts and when in the motorcycle if you do a check with the engine running around 2000 rpm it should read around 13.5 volts all the way up to 14.5 but never higher it will fry the battery...Best batteries are the saturated gl mat batteries ..they never leak ..last a long time.. can be mounted in any position...
