What's worse than your cordless tool dying in the middle of a project? Your drill won't work because the battery is dead? It's a problem that you never want to happen.

Tools that are cordless are so essential nowadays. Any issue with them can cause real inconvenience and frustration for homeowners who rely on their Black & Decker 18v batteries.

From power drills to vacuum cleaners, it seems like we use rechargeable batteries in everything! So what would you do if your black and decker 18v battery won't charge?

In this brief article, learn some common reasons why this kind of battery won't charge and be able to learn how this could be fixed the way it should.

Some Black and Decker 18V Battery Charger Problems

Unplugged

The battery is not plugged into an outlet, or there is a break in the circuit between the charger, battery, and cord.

Not enough voltage

There is not enough voltage coming from the circuit breaker or power strip. If you have other devices which require electricity on this circuit, you will want to figure out which device has priority first before trying to charge your Black and Decker 18V battery again.

The battery is not in good condition

The battery may not be in a good condition, and if it is not then your charger might tell you that there's nothing wrong with the device.

Chargers are capable of testing voltage output on batteries to see what level they're at before charging them up again.

Faulty charger

One of the most common reasons for a Black and Decker 18V battery not to be charging is a faulty charger.

Bad quality chargers will usually have a short period of time in which they work and then stop working.

This would make any device that's plugged into the charger useless.

Dead indicator light

If you notice that the indicator light on your charger isn’t working, it might be time to check for any other common issues.

A dead battery is a good place to start since whether or not the device will charge depends on how much juice is left in the power source.

Sensitive batteries

Batteries are delicate, and can't handle being too hot or cold. If your battery is either of these two things, it may not charge properly.

Unplug the battery for around 15 minutes if it's too hot; then try to connect to a charger again! Alternatively, you could move the charger to a heated room (or just leave them in there) for an hour/two before trying again.

Dirt and corrosion

Dirt and corrosion on the charger's contacts can prevent electrical flow, but it is easy to fix. First, unplug the charger for safety reasons then use either a small screwdriver to scrape off any corrosion.

If access becomes difficult there's a need for some contact cleaner which will clean them right up! Once they are both nice and shiny try charging again!

Light's out!

If the charger's light is out, try connecting to a different outlet. A black and decker 18v battery may not charge because of a faulty electrical outlet.

FAQs

Is there a warranty for Black and Decker 18v Battery?

The Black and Decker warranty typically covers their products for 180-day parts and labor warranty. If your product isn't working they may offer to fix or replace it with its equal or greater value.

Black and Decker also have a battery guarantee which covers many of the batteries over two years old. Contacting their customer service department before trying any other methods may void your warranty, so this is one step to consider.

What is the lifespan of an 18v battery?

The lifespan of a typical 18-volt battery ranges from one year to two years. It depends on use and how often you recharge them.

If you have an older Black & Decker cordless power tool with less than 2-year-old that is not working as it should be, then get in touch with the Customer Service Department right away for possible replacement under Warranty.

Is it worry-free, if the battery is left unplugged?

One of the many things that people forget to do after charging their battery is unplugging it.

The charger will power off automatically when the battery is fully charged.

Letting it continue to charge may cause issues or can be dangerous for both the charger and the battery because they might overcharge or get too hot if left plugged in.

Whether you’re new to the world of power tools or just looking for a refresher, we hope this guide has helped. We want to remind you that battery life is important and it will be difficult if your tool suddenly stops working because of an empty battery.

We hope that the guide above may have helped you identify the problem why your black and decker 18v battery won t charge. If not, we hope it has at least given you some useful tips for maintaining your power tools so they last longer.
