Battery technology has trailed behind nearly all the other advances of the portable system. A battery life of two hours is considered very good even when a system's power-saving features are utilized. Some manufacturers are designing systems that hold two batteries to try to overcome this limitation.
A fourth type of battery technology—the lithium polymer—has been in development for several years, but it has not yet appeared on the market. Lithium polymer batteries can be formed into thin, flat sheets and installed behind the LCD panel. They provide approximately 40 percent more battery life while adding far less weight to the system.
TIP
________________________________________
All battery types function best if they are completely discharged before recharging. Even lithium ion batteries perform better and last longer if they are discharged before being recharged. You can also store charged batteries in the refrigerator to help them maintain their charges longer.
Proper Battery Disposal
Many people give no thought to discarding exhausted batteries in the nearest trash container, but you should take a more professional approach. Batteries contain hazardous and environmentally detrimental materials. Be sure and check your company policy and recommendations from the manufacturer before disposing of any battery. Failure to do so is both poor practice and an invitation for a fine.
