Dell Inspiron 2500 - Manual (Page 105)

Appendix 105
The coin-cell battery is a long-life battery, and it is very possible that you
will never need to replace it. However, should you need to replace it, the
procedure must be performed by an authorized service technician.
Do not dispose of the battery along with household waste. Contact your
local waste disposal agency for the address of the nearest battery deposit
site.
