Can a 12V battery stay at 17 volts?
I’m not sure you can get a lead acid 12v battery to stay at 17-18 volts no matter what you did to it. If your charger is working fine on your bike it’s probably OK. If your buddies battery has a bad cell or other problem your charger may be trying too hard to charge it.
Why does my bike Charger read 17 volts?
If your charger is working fine on your bike it’s probably OK. If your buddies battery has a bad cell or other problem your charger may be trying too hard to charge it. I notice that the new Optimate chargers now have bad cell detection to avoid this problem.
What should the voltage of a motorcycle battery be?
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 drops in voltage, there is a problem. If the voltage instantly drops to 0 volts,…
How can I tell if my motorcycle battery is over charged?
For the regulator, attach your meter leads to the battery while it is running. It should not read higher than 14.5 volts and no lower than 13.5 volts. If it is higher, the battery will be over charged and if it is lower, the battery will continue to drain as the bike runs. If these tests do not check out, you will need a new regulator/rectifier.

What should battery voltage be on Yoru bike?
Click to expand… do the above.. and while disconnected measure the voltage of the battery disconnected from the charger… again it should read somewhere in the range of 12 – 12.7 / .8 volts…. if not it may still be a charger problem, I ma nots ure of the design on yoru bike but there may be a coltage regulator that is faulty….
