A healthy 12 volt motorcycle battery should maintain a range from 9.5 – 10.5 volts under the load, for a good 30 seconds straight. If the battery begins to hold and then steadily declines, there is a problem.
How many volts should a motorcycle battery show?
A fully charged battery should read approximately 12.6VDC. If it reads at or below 12VDC, recharge the battery. Allow battery to rest and test again. A battery that has been fully charged, rested, and tests between 12 and 12.6VDC might start the motorcycle, but it’s not holding a full charge.
How many amps does a 12v motorcycle battery have?

How do I check for a battery drain on my motorcycle?
The way to check is to remove the negative battery cable and place your volt-ohm meter in the current (amps) mode.

The current draw should be zero, but a small drain on the order of a few milliamps is acceptable.
Will a motorcycle run with a bad battery?
Registered. Yes a bad battery can make motorcycles not run well, shorted cells in the battery will cause the voltage coming from the alternator to get shunted to ground, eventually as more cells short out this will drop the voltage low enough that it will affect the fuel pump and the ignition coils.
Can you leave a trickle charger on all the time?
Trickle chargers are low-amp chargers that top up a drained battery to keep it at its maximum capacity. … It can be left on indefinitely, charging a car if you only use it once in a few months, and it will ensure that the battery never goes flat.
