How long can you leave a trickle charger on your motorcycle battery?

The time distance you can leave a trickle charger on motorcycle banks on the charger you choose to use. If you are utilizing a maintenance trickle charger, it provides a sufficient charge to keep your battery fully charged at all times.

The maintenance trickle charger protects the battery by providing the lacking charge during self-discharge with a consistent voltage. So, if you choose to use the maintenance trickle charger on your motorcycle for a long period, it would not harm the battery.

However, if you are using a basic trickle charger, it charges at a limited rate. if the trickle charger reads 1.24 amp, use the amp/hour of the trickle charger to divide the 1.24 amp. For instance, let’s assume the amp/hour is 19, then you would say 19 amp/hour divided by 1.24 amp which equals 15 hours and some minutes.

This implies that if you use a basic trickle charger, you can leave it on your motorcycle battery for about 15 hours and some minutes. If you leave the trickle charger on your motorcycle for more than 15 hours, the hotter the battery would be.

 Technically speaking, the more this basic charger is attached to your battery, the more the battery would get hot, and with time the battery would get dried. It is advisable to get a maintenance trickle charger for your motorcycle battery.
