What Should A 12 Volt Car Battery Read. If the battery begins to hold and then steadily drops in voltage there is a problem. If it reads 126 volts the battery is just attaining a fully charged state.

A healthy 12 volt motorcycle battery should maintain a range from 95 105 volts under the load for a good 30 seconds straight.
