The A3000 is, I think, the only Amiga model that stores some SCSI controller settings in memory that is backed by that battery (in addition to the Real Time Clock). Probably, default values are used if the memory is corrupt, don't know for sure.
It is not difficult to substitute a better battery AND remotely mount it so a leak is much less consequential. I personally prefer rechargable cordless phone batteries.
No offense ,but i think its dumb to mount ANY battery in a amiga that can leak when there are better alternatives like coin cells.
what you guys don't realize is the leaking batteries often outgas when they leak which is why on some amiga boards you may see corrosion far away from the battery on other components.the fumes inside the case travel.
If you don't like the typical 3volt CR2032 cells, use the LIR2032,its a rechargeable coin cell lithium that fits inthe same cell holder (you must still use the diode),but it starts at 3.6v instead of 3v and will generally be better off with the diode voltage drop and last longer. there are external wall chargers to recharge this coin cell,like the old cr2032, again it should never be charged by the amiga.
The 3000's battery mem holds several things, it allows the use of LUNS,it holds time and date,and allows you to set scsi into synchronous mode for better speed. it also holds settings for Speeding ramsey for ram access if i recall.
