Epson LT-286 - Manual (Page 62)

Using the Battery
The battery pack inside the Equity LT-286 contains eight NiCad
(nickel cadmium) batteries that power the computer when the AC
adapter is not connected. The battery pack is rechargeable, and you
should never have to replace it.
You need to recharge the battery pack at the following times:
l
Before using the computer for the first time
l
If the battery has not been used for a long time
l
If the Power/Speed indicator light starts flashing (see “LED
Indicators,” below).
After the Power/Speed light starts to flash, you have a maximum
of 10 minutes before the battery charge is completely gone. If you
continue using the computer without connecting the adapter,
power runs out and you may lose data.
To recharge the battery, connect the AC adapter to the computer
and to an electrical outlet. You can charge the battery whether the
computer is on or off. For the maximum charge, leave the AC
adapter connected for 12 hours. The battery pack cannot be
overcharged, so don’t worry if you leave it connected for more than
12 hours.
Remember the following when you are charging the battery:
l
Use only the AC adapter that comes with the Equity LT-286.
Using a different one can damage the computer.
l
It is best to charge the battery for at least eight hours. If you
charge the battery for only short periods, it can run low sooner.
The length of time the battery can provide power after being
charged depends on how you are using the computer. A fully
charged battery provides approximately one hour and fifteen
minutes of use for simple operations. If you are working with a
program that makes extensive use of the hard disk or if you are
using an external diskette drive, you may need to recharge the
battery sooner.
