Motorcycle Battery Voltage At Rest

If a battery reads 12 volts at rest it is almost fully depleted.

Motorcycle battery voltage at rest. A fully charged 12 volt battery allowed to rest for a few hours or days with no load being drawn from it or charge going to it will balance out its charge and measure about 12 6 volts between terminals. Start the engine and check the voltage while doing so. A healthy 12 volt battery should ideally register around 12 7 12 8 volts at rest but anywhere between 12 5 13 5 volts indicates a serviceable battery. Whats people lookup in this blog.

The following table shows how battery voltage corresponds with state of charge at 80 degrees f. Step 3 shift your motorcycle into neutral. Once a battery drops below 12 4 volts your bike will struggle to start and at under 11 8 volts 12 volt batteries are considered to be dead. Even though you are testing a 12 volt battery you should know that a battery that is truly 12 0 volts is a boat anchor.

The resting voltage should be approximately 12 5 volts. The primary battery voltage is dictated by the chemistry of the lead acid cell. When a battery reads only 12 volts under the above conditions it s almost fully depleted. For example a fully charged battery at rest should be between 12 6 and 12 75 volts.

Motorbike batteries are made up from a combination of such cells connected in series to give the required voltage. If my battery dies can i recharge it. What voltage should my motorcycle battery read.
