You should use the battery at least every 2-3 weeks. Do not keep a Li-ion batteries completely discharged for a long time (keep the protection circuit alive). Store you laptop battery at 40% state in a cool dry place (The suitable temperature is about 15°C). We recommend charging the g61 battery under the threshold voltage when machine turned off. Do not setting a metaillic object on your battery connect metal, or it will cause short-circuit. Avoid your battery heat up: keep them away from hot, pillow, blanket, or other soft surface. The battery is a lot less efficient when not within its standard operating temperature range ( -10~40°C ). Via: http://starmall.co.uk
