obviously not. then you just have to keep buying batteries.
happily, i don't own any of those. i collect vintage bikes.

The regulator output to charge a 12 Volt batter in a car or motorcycle
should be 13.8 Vdc. 30 minutes after charging it measure the open circuit
voltage. It shoud be 12.8 V or better, if not the batter is not fully
charged. Battery Tenders are not battery chargers they just maintain a fully
charged state. If your battery will not hold a charge equal to or greater
then 12.8 volts after charging over night then the battery is on it's last
legs.
