New Batteries
When buying your next laptop, be sure to consider the computer's power requirements and performance. Pay attention to what battery comes with the machine, the run-time and cost of additional batteries, the ease with which new batteries can be inserted or attached and the time it takes to recharge batteries. Too often people focus only on a computer's great new features and ignore the power requirements of those features. No one likes to lug around several extra batteries just to keep a computer running on a long trip.

New batteries are generally not charged before they are delivered because the charge is not stable during the shipping process. You should fully charge and discharge a new battery as soon as you receive it. As a rule, a new battery must be fully charged and discharged at least five times in order to realize the maximum run time.

A new battery may cause the battery status indicator on your computer to indicate a dead or low battery condition. If this should occur, remove the battery and then re-insert it. If you still don't get a full indicator, let the battery charge in your computer overnight then discharge fully and recharge 3 - 5 times.

Battery Storage
Do not store batteries in extreme temperatures or wet areas. For example, do not leave your cellular phone or laptop in your car during the heat of the summer or the cold of the winter.
