What does it mean when your battery is reading 0 volts?

If your battery is: Reading 0 volts, chances are the battery experienced a short circuit Cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell Fully charged (according to the battery charger) but the voltage is 12.4 or less, the battery is sulfated

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 the voltage of a battery be when it is fully charged?

Cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell Fully charged (according to the battery charger) but the voltage is 12.4 or less, the battery is sulfated Sulfation is the natural byproduct when the battery discharges.

What causes the voltage to drop on a new battery?

On a new battery, this can be a result of manufacturing flaws, but it also may be caused by sulfate crystal buildup. Under the intense heat of the load, one or more of the weld pieces connecting the cells is coming loose and separating. This will cut the current, and voltage will drop.

What is the voltage as you trigger the starter?

12.4v is a bit low for a good battery though – should really be 12.7v, so might be that one of the cells is on the way out which of course won’t help. What is the voltage as you trigger the starter? My battery was doing the same when I had a dodgy cell. Sure its not the starter or the wiring rather than the battery?

Why does my battery only show 12.4v?

12.4v is a bit low for a good battery though – should really be 12.7v, so might be that one of the cells is on the way out which of course won’t help. I see what you mean, basically a dodgy terminal connection could still show 12v at the starter but can’t deliver the ‘ampage’ when put under load?

What’s the voltage on a Harley Davidson starter?

I check the voltage at the kill switch and get 12.3 from the black and white wire that goes to the kill switch and the start button. But, I only get 9.2 volts from the black and red wire from the start switch to the start relay. All the fuses are good and there are 12 volts to the starter and the solenoid.

Why does my car battery not start while running?

As of yesterday, will NOT start on battery. WILL always start when push-started (so far). While running, will stumble at idle with lights on, and voltage meter shows spikes when turn signal on. Initial Conclusion: The battery (via loose connection or ???) is somehow being isolated from the system.

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 can you tell if a battery is fully charged?

The voltage of a battery is a good way to determine the state of charge. Here’s a handy table with the breakdown: Cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell Fully charged (according to the battery charger) but the voltage is 12.4 or less, the battery is sulfated

Why does my starter on my 5055e not turn over?

Starter on 5055E wont turn over. Turning key just results in Starter on 5055E wont turn over. Turning key just results in “clicking”. Is this a selenoid problem? … read more I have a Deere 4310 that I was driving today. I shut it off I have a John Deere 4310 that I was driving today.

What happens when the dashboard battery light comes on?

Your car can often run normally even if the dashboard battery light comes on because the car is capable of running off the energy that is already stored in its battery. The car, therefore, carries on running perfectly until its battery runs flat. After that, none of the car’s components will work.

Why does my new Honda mini not start?

There’s a brand new starter in the for sale section. have you tried the other key? small chance it could be the key. The battery in the mini does odd things when duff, not always what you expect also most minis with flat battery will not jump start they however will bump start almost all of the time.

Why does my battery light keep coming on?

There are several possible answers. Here are a few of the most common issues that can cause this light to come on: Corrosion of the battery terminals is a relatively common occurrence. This often becomes obvious because the vehicle becomes hard to start due to the starter motor turning over slowly.

Why is the battery not working on my R53?

Fuel pump primed lights came on the dash, went to start and nothing just a ticking noise from what I thought could be a dodgy starter. After seeking advice from Coastal, Carl said the battery could have dropped a couple off cells due to the cold which is causing the problem (scanguage showed battery voltage at 8.5-9v).

What should the battery voltage be when the car is running?

The voltage, when the engine is running, should be in the range of 13.5-14.7 volts. When your car is running the cars alternator is charging the battery, this is why you should see a higher voltage. If you’re readings are significantly higher or lower than these then it would indicate a fault with the battery and/or the alternator.

What does it mean when battery voltage is 12.2v?

Measuring the voltage shortly after the engine has been running can give you a higher, misleading, reading. If the voltage is below 12.6v it indicates that the battery isnt fully charged or has a fault. The voltage doesn’t have to differ much from 12.6v for it to indicate a discharged battery. At 12.2v the battery is in effect 50% discharged.

What does it mean when battery voltage is below 10V?

If your test shows that this voltage is below 10V, this typically means that the battery has been left in storage for too long without a charge or left with a load running on it that doesn’t have an automatic cut-off.

What causes battery to drop voltage when fully charged?

If your battery shows a good voltage when it’s fully charged, but quickly drops voltage to 11V or less when using power, this usually means the battery has a faulty cell and needs replacement. This can be caused by excessive vibration such as driving over corrugations without adequate shock absorption for the battery, or a manufacturing fault.

What happens when a battery is charged but not fully charged?

Fully charged (according to the battery charger) but the voltage is 12.4 or less, the battery is sulfated Sulfation is the natural byproduct when the battery discharges. Naturally, re-charging the battery will reverse the sulfation crystals and turn it back into electrolyte, ready to produce power again.

Do you have to fully charge a battery for a load test?

For any load test to be accurate, the battery must be fully charged. Let’s use a motorcycle battery for an example: Remove the seat and expose the battery in your bike so that you have access to the terminals. Do not disconnect the battery because you will attempt to start the bike.
