Kobalt 80V Battery Not Charging – Causes & Solutions

Table of Contents

The Kobalt 80V is an excellent device for charging your electric tools when having different projects. They are easy to move around and are a reliable source of power.

With proper maintenance and use, you can continue to enjoy the battery services for years. However, there are instances in which the Kobalt 80V battery stops charging.

This problem is often due to several common reasons for power appliances. Checking out the possible reasons helps you to find an appropriate solution.

Reasons Why Kobalt 80V Is Not Charging And Solutions

For the device to charge, two different components have to be in perfect condition: the battery and its charger.

Faults or defects relating to the two can cause your Kobalt 80V battery to stop charging. Here are some possible reasons relating to both the battery and its charger.

Power Cord

It is easy to assume that the error is with the device when your Kobalt 80V battery is not charging.

However, some errors are the result of issues regarding the battery charger. One such issue arises when the power cord is a problem.

The power cord supplying a connection to the charger can become defective, preventing charging.

The issue with the power cord might be due to cuts and twists in the cable length or a loose connection at the end of the cable.

These are common faults that can arise with the power cord.

Solution

If you suspect the power cord is the issue, there are a few steps to confirm your suspicion.

The first thing is to remove and reconnect the power cord to be sure it is not a simple error. The next step is not to check the power cord’s plug at both ends.

The last option is to check for cuts or bends on the power cord.

Any of these steps should confirm that the power cord is defective. The simple solution is to buy another power cord.

Alternatively, you can visit a repair expert to check out and repair the power cable.

Main Fuse Blown

Another vital component of the charger is the main fuse. You might not know about the primary fuse if you are new to how electrical and power-related devices work.

It is an interior component and a failsafe unit responsible for protecting the charger.

The main fuse blows out when a power surge occurs due to high voltage or the wrong connection. The aim is to prevent power surges from damaging the charger.

Because it is an interior unit, it is not always obvious when the fuse blows out. When this happens, the Kobalt 80V battery stops charging.

Solution

Checking the main fuse requires a bit of expertise. However, if you have the right tools, you can always solve issues regarding the main fuse.

You can open the charger and remove the fuse with the right screwdriver.

The owner’s manual can help know which part of the charger needs unscrewing. After removing the blown fuse, it is essential to replace it with a proper fuse.

Fuse comes in different power capacities and sizes, so you can use the faulty fuse to get a replacement. Properly screw the cover and other units after the sub; you are good to go.

Defective Charger

Other than the power cord and the main fuse issue, some other problems can affect the charger and cause your Kobalt 80v to stop charging.

One typical example is connection issues at the terminals. The charger might fail to indicate when the battery is connected.

Another reason is defective LED lights. The device uses LED lights to indicate power connection, percentage, and charging progress.

This is also true for the battery’s charger. When the light becomes defective, it stops showing the charging progress of your battery.

That is one example of an issue that can affect the battery.

Solution

Sometimes, routine maintenance can help solve the issue. It is because dust and debris can cause connection problems with the charger at the terminal.

Cleaning the terminals can help restore the connection with the Kobalt 80v battery. In some cases, this step is ineffective.

A general inspection by a local repair expert can help identify the problem with the charger. Hence you can determine if you need to repair or replace it.

You only need to repair the battery charger if the problem is with the LED lights.

Battery Discharge

One of the common issues that can contribute to charging issues is discharge due to prolonged inactivity of the battery.

There are times when you have no use for your battery. Most people store it away in the tool store. However, this can lead to problems when it is in store for a long time.

When the battery is stored and not used for long, it starts to discharge. The battery becomes defective if it discharges beyond a certain level known charging threshold.

When you finally need to use this device, you realize your Kobalt 80V battery is not charging.

Solution

The only solution to this problem is the preventive step. You can prevent the discharge by charging the battery regularly.

You can schedule a time for this step even if the charger is not used.

In situations where the deed is done, the best option is to get a new battery. The cells are damaged and dead, and any attempt at recharge is not advised.

It is better to get a new battery and maintain it as much as possible.

High Temperature

When cells move around in the battery, the temperature of the device increases; in other cases, the working environment is responsible for the temperature rise.

When there is an increase in temperature, the Kobalt 80V battery stops charging even where there is no error in connection.

Plugging the device while the temperature of the device is still high affects the system. In some cases, the device does not charge.

The persistent connection to the battery charger can lead to discharging. It significantly reduces the battery life.

Solution

When the battery temperature is too high, please remove it from the charger. It is best to wait a while before reconnection.

This step should solve the issue in most cases.

Also, it is best to use the battery in excellent condition. Using it in calm conditions allows for optimal functioning without raising the temperature.

It is also best to check the usage habit to confirm that the battery is appropriately used.

Maintenance Tips

Some common maintenance tips can help prevent issues leading to your Kobalt 80V not charging. This tip is also helpful for the charger.

They are as follows:

Avoid using the entire Battery capacity before recharging.
Ensure you properly store the devices in safe conditions. It is best to avoid too hot or too cold conditions. Water can also affect the batteries and lead to short-circuiting. It is best to keep the battery in dry conditions.
Regularly clean the battery and charger using dry wipes. Removing dust and debris helps to keep the units in optimal condition.
It is best to seek expert services when repairing any part of this battery. Handling without expertise can lead to battery-induced injuries or over-complication of the problem.
