How to Change Batteries on a Cordless Black & Decker

One of the conveniences of cordless power tools is that you can use them where there is no power. Cordless tools operate using rechargeable batteries. Black & Decker manufactures a full line of cordless products including power tools and lawn equipment. Changing batteries on a cordless Black & Decker depends on the type of tool you are using. Most Black & Decker products either have tabs on the side of the battery or have a retaining handle which secures the battery to the tool.

Press the release button on the side of the battery near the base of the tool with your fingers. Most Black & Decker power tools and some of its yard trimming products use this type of battery.

Hold the tool in one hand and pull the battery out with your free hand. Take a fully charged battery and insert it into the tool. The battery only goes in one way. Press the bottom of the battery until it snaps into place.

Pull the lever securing the battery forward on Black & Decker mower batteries. Some lawn tool products also use this type of method to secure the battery.

Lift the battery straight out and set a charged battery into the mower or yard tool. Pull the retaining handle back over the battery.

Insert batteries into their respective charger and plug the charger into the wall socket.

Batteries Leak?

While most batteries get used and disposed of before ever presenting a problem, very old or damaged batteries are prone to leaking. In some cases, the batteries may simply be defective. It can also cause damage to any electronic device the battery was in when it leaked, which is why you should always remove the battery before storing any battery-operated devices. Potassium hydroxide from a leaking battery may cause poisoning if ingested or inhaled. Poisoning symptoms include severe abdominal pain, breathing difficulties, diarrhea, and a rapid drop in blood pressure, to name a few. Do not induce vomiting unless instructed to do so by the physician. To remove the leaking fluid from a device's battery contacts, use an acid like lemon juice or vinegar and a cotton swab. Proper handling and care is the best way to avoid the potential consequences of a battery leak. Never mix old and new batteries or two different battery brands.

Tip

Although most of the line of power tools do have replaceable batteries, not all cordless products have removable batteries. Battery-powered tools and equipment that do not have rechargeable batteries usually have a plug-in adapter for charging.
