HITACHI Cordless Tool Battery Replacement, HITACHI 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.

Protect Loose Tool Batteries - Although power-tool batteries are durable, they're still prone to damage from rough or improper handling. On a project site, keep loose batteries stored in separate compartments in a padded bag or in the original tool cases, protected from direct sunlight and rain. Make sure the batteries are kept in a moderate environment, not inside a hot vehicle. At home, keep drill batteries in storage cases.
