Warning About The Lenovo SB10K12721 Batteries

If your capacity drops faster than you think, it means you should treat your Laptop Battery in time. Do not leave your Lenovo battery SB10K12721 dormant for long periods. We recommend using the battery at least once every two to three weeks. It's a good idea to store the laptop part in a dry and cold place if it is not used. Clean the battery's metal contacts with rubbing alcohol on a damp cloth. Clean contacts increase energy efficiency. Turn off the wireless devices. This will save the Lenovo SB10K12721 battery power. Batteries degrade more quickly when they’re hot.
