It is quite common after a few years for Amiga 1500's, Amiga 2000's and Amiga 4000's to have a leaking real-time clock battery.
 
Replace it before it corrodes your Amiga motherboard with this 3.6V surface mounting Ni-MH battery. This barrel battery has three contact legs for connection to the Amiga motherboard.
