Well, I was wondering why you couldn't get the battery out as my travelmate has it easily accessible... upon reading further I saw you meant the CMOS battery... well.. I've seen quite a few laptops and have never seen one with an easily accessible battery... :)

Thanks for the info just about to change the cmos in my old Acer 803. One question can you remember the battery code/number ?

The battery is an ML1220, you could also use a CR1220.

Amazing after all these years that your Blog on your old Acer Travelmate 803 is still very helpful :-)
I looked everywhere for info on the cmos battery location and type and found it finally here.
Many thanks Jan and I wish you luck with your christmas concert in the OLV Sint Pieterschurch.

Did you actually try a CR battery here? I'm afraid to use a CR1220 as they are not rechargeable. However, I can easily purchase a CR1220 at the drugstore.

Can't find ML1220 (rechargeable) anywhere but on-line. They're not expensive but wanted to get the laptop put back together right away. I'm afraid of the unit attempting to re-charge the non-rechargeable battery and having a disaster.

Having the same problem with an Acer 4630Z laptop. Same complete disassembly required. Total pain.

I believe I got an ML1220 at a local photography store. Not sure about the CR1220 anymore, though. It's been too long.

Did anyone here ever try the CR1220 battery? I'm having the same dilemma..

here, they say to never use CR1220 as it is not rechargeable:
