The battery does not hold a charge after completely charged-suspect the charging system-the Honda shop technician said nothing is wrong with the charging system or the battery.

Hi and welcome to fixya,


Try checking for short circuits, it usually is a worn out wire (positive) touching against the chassis (negative). It could drain the battery in no time. Also, how did the honda shop technician tested the battery? I use an automatic charging system that detects errors on charging and I had the same problem with a battery not holding charge. Using the charger, it detected it with with an error code that interprets to be "Battery Sulfated" thus concluding battery is indeed dead.

One quick test you can do with the battery is to open the reservoir caps (be careful and use gloves as this is a very strong acid). Get a wire and short the two contacts momentarily or for about 2 seconds. If you see the liquid inside boil, then the plates are worn or sulfated.

The quickest solution for this problem is to buy a new battery. There's a great chance your bike's charging system is still working but if your battery is quite old, lets say 2 years. It could be dead. Replace with low maintenance types, they are expensive but stands the test of time, more rugged and worth it.

Hope this info helps
