What should a 12v motorcycle battery read?

Is 12.4 volts OK motorcycle battery?

12.6V volts or above – Your battery is healthy and fully charged. No further action is required. … 12.1 – 12.4 volts – Your battery is partially discharged and should be recharged as soon as possible, using a suitable battery charger.

What is normal voltage for motorcycle battery?

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 declines, there is a problem. If the voltage drops to 0 volts, there is a problem. We call this, the open cell.

What is the correct voltage for a motorcycle battery?

Most of the motorcycle batteries are the conventional ‘lead-acid’ batteries. These batteries can be either of 6 volts or 12 volts. If the batteries are in good condition, then the actual value of voltages isn’t these values. When the battery is charged fully, and it’s at peak, the terminal voltage of each cell is 2.1V.

Why is my 12V battery 14v?

This voltage range means the battery is in good condition for starting the vehicle. If the measured reading is less than 12.2 volts, the battery’s resting voltage is weak, which means it most likely needs to be charged or replaced. … With the motor running, the multimeter rating should stay in the 14 to 14.5 volt range.

How do I know when my motorcycle battery is fully charged?

A fully charged battery should read approximately 12.6VDC. If it reads at or below 12VDC, recharge the battery. Allow battery to rest and test again. A battery that has been fully charged, rested, and tests between 12 and 12.6VDC might start the motorcycle, but it’s not holding a full charge.

How low can I run my 12-volt battery?

No 12-volt battery will remain at over 14 volts for more than seconds unless it’s being charged. The lowest limit is 10.5 volts (used in testing) and obviously unsatisfactory in practical use. Experienced RVers try to use no more than 20% to 50% of the energy available in a battery before recharging.

How many volts is a Harley Davidson motorcycle battery?

Harley-Davidson motorcycles use either a 6 volt or a 12 volt battery. Harley-Davidson motorcycles made after the early 1960s are using 12 volt batteries, while older Harleys made before the early 1960s are using a 6 volt battery. If a Harley was made in the last 40 to 50 years, it uses a 12 volt battery.
