Replacing The Lithium Battery - Fujitsu Celsius C620 Operation Manual

Replacing the lithium battery

A lithium battery is installed to supply the CMOS memory with power so that the system information
can be permanently stored. An appropriate error message is issued when the battery voltage is too
low or the battery is discharged. The lithium battery must then be changed.
If the lithium battery is incorrectly changed, there is a risk of explosion!
!
The lithium battery may be replaced only with an identical battery or with a type
recommended by the manufacturer.
Do not dispose of lithium batteries in household waste. They must be disposed of in
accordance with local regulations concerning special waste.
Make sure that you observe the correct polarity when replacing the lithium battery. The
positive terminal must be at the top!
The lithium battery holder exists in different designs that function in the same way.
