# What is a good battery voltage reading?

## What is a good battery voltage reading?

Check the reading. A fully charged battery will typically display a voltmeter reading of about 12.6 to 12.8 volts. If your voltmeter is showing a voltage anywhere between 12.4 and 12.8, that means your battery is in good shape. Any voltage above 12.9 volts is a good indicator that your battery has excessive voltage.

## How much should a fully charged motorcycle battery read?

When a battery charger has been disconnected from the battery for one to two hours, a fully charged Conventional battery should read 12.6 volts (12.8 volts with Sulphate Stop) or higher. AGM batteries may have slightly higher voltage readings after a full charge. Do Not Overcharge.

## 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,…

What should a 12 volt battery read under load? 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.

## How can I tell if my motorcycle battery is good?

Now push the start button and watch what the voltage drops to. It doesn’t matter if the bike starts or not, what you’re looking for is a voltage reading. 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.

## How do you measure the voltage of a bike?

Turn the multimeter on to the 20V DC section of the scale. (If you have an autoranging meter, just go to “V,” because you won’t have a scale.) With the bike completely turned off, touch the black lead to the negative post of the battery, and the red lead to the positive post. Record the voltage.

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 test the battery on my new bike?

After the voltage has been tested, make sure the voltage displayed on the multimeter matches the voltage in the bike’s specifications. Then, check the current. The reading that the multimeter gives will indicate the capacity of the battery. Finally, use the multimeter to check the battery’s resistance.

## When to change your motorcycle battery and understanding?

If a battery reads 12 volts at rest, it is almost fully depleted. The full range of the battery is from just over 14 volts (when being charged by the bike running at high RPMs) down to 10.5 volts (under heavy load, for example, when the lights are on and the bike is being started). 5) Use a multi-meter and test your battery’s voltage range.

## 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.
