While we were all scratching our heads wondering how to make our batteries lost longer, he called up Isidor Buchmann, the Ceo of Cadex Electronics, a Canadian company that makes battery-testing equipment to get a few tips on how to make sure your battery goes on and on and on and …

The best technique here is to charge up your battery when the computer is turned off.
