Maximizing Battery Life; Charging Batteries - Toshiba Satellite 1805 Series User Manual

Never incinerate a spent battery as this will cause it to explode
and release toxic materials.
If a battery is leaking or damaged, replace it immediately. Use
protective gloves when handling a damaged battery.
To replace the main battery, use an identical battery that you
can purchase through www.toshibaaccessories.com.

Maximizing battery life

A main battery can be recharged many times. Gradually over time
it will lose its ability to hold a charge. To maximize the life of your
main battery:
Avoid leaving the computer plugged in and unused for more
than a few hours. Overcharging the main battery may shorten
its life.
If you are not going to use the computer for a long period of
time, remove the battery.
Alternate between battery packs if you have a spare.
Make sure the computer is off when you are replacing the
battery.
Store spare battery packs in a cool dry place out of direct
sunlight.
TECHNICAL NOTE: Battery life and charge time may vary,
depending on applications, power-management settings,
and features used.

Charging batteries

The main battery needs to be charged before you can use it to
power the computer.
