Drain fully during usage and recharge fully. Use it till you get the low battery warning then charge it completely. Also do not leave a charged battery dormant for long periods of time. The battery should be used at least every week. 6. Resist the demand for using multiple tasks. The additional programs you have up and running use more electricity. Quit all the programs you are not currently using. 7. Avoid using laptops in high temperatures. Laptop batteries are made to function correctly within a few degrees of room temperature and always avoid using or charging your laptop in hot or cold conditions.
