Title: Amiga 4000T Battery
Post by: mdivancic on March 01, 2009, 03:06:24 AM

The battery in my 4000T is long dead. I'm looking for a battery pack right now. Is there any problem leaving the old battery on the Mother Board?

 A4000T uses:

 C= version: a coin shaped rechargeable lithium cell. No leak.

 Escom: a coin shaped no-rechargeable lithium cell. No leak.

Both uses no-rechargeable lithium cell.

Take the coin cell out and put one of these babies in:

Note the coin cell is spot welded to a retaining tab. You have to prise it off or desolder the tabs from underneath the mobo (which is a major pain).

Radio Shack carries the replacement battery as shown in the photos.

I asked about leaving the battery in because I don't want to pry on the MB or take the whole damn thing apart and desolder it. IF there is no chance of leak I'm leaving it in.

Radioshack's variant is 4.5V which some early AT pc's had...not sure if it's a good idea to use it on the A4000T which has a 3.6V battery
