BLACK & DECKER Cordless Tool Battery Replacement, BLACK & DECKER Generic, Brand New Compatible Batteries

Cordless powertool batteries are rugged instruments designed to perform tough jobs, but they still require care to maintain safe, optimum performance. There are steps users can take to extend tool and battery life, and help keep power tools operating at peak performance for a longer life cycle:

Moderate Temperature, Most Battery Life - The temperature of the battery while it charges also affects its lifespan. If you are using a battery outdoors on a cold winter day, charging it outside could result in permanent damage that shortens battery life. The same holds true when charging a battery that's been exposed to summer heat and full sun all day.

Preventing the Memory Effect - Keep your cordless drill batteries healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-ion batteries which do not suffer from the memory effect.

Keep Your Batteries Clean - It's a good idea to clean dirty power tool battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and your portable device.

Exercise Your Battery - Do not leave your battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new power tool battery break in procedure described above.

Battery Storage - If you don't plan on using the battery for a month or more, we recommend storing it in a clean, dry, cool place away from heat and metal objects. Ni-Cad, Ni-MH and Li-ion cordless drill battery will self-discharge during storage; remember to break them in before use. Sealed Lead Acid (SLA) batteries must be kept at full charge during storage. This is usually achieved by using special trickle chargers. If you do not have a trickle charger, do not attempt to store SLA batteries for more than three months.
