- Summary: I don't like things that go plop-plop fizz-fizz inside my Amiga.

- This may be in a FAQ somewhere by now, but I could not help but wonder:
-
- Has there ever been a real solution found for the battery backup timebomb
- problem found? For those of you not familiar with this, lurking inside
- every Amiga with a battery backup, there is a non-removable battery which
- may just die quietly someday, if you're lucky. Or if you're not lucky,
- it could spew caustic chemicals all over your motherboard traces, leaving
- you with a very expensive, once multitasking, doorstop. And one heck of
- a bad temper.... This is also true of bridgeboards that have battery
- backed CMOS/setups, and being a bridgeboard user, I am equally interested
- in finding a solution for that also.
-
- One possible plan that I've thought of was to maybe clip off the
- battery claw on both sides as far away from the motherboard as possible,
- leaving stubs, to which wires could be carefully soldered using low heat.
- The wires could then be connected to a more intelligent *removable*
- battery socket glued somewhere to the inside of the case. Is this a
- possibility? Would I be left (in both the case of an A3000 and for an
- A2386SX) with enough of a metal stub to be able to solder something to?
- Is there a source from which similar, long lasting batteries like the
- ones being used in the A3000T and the A2386SX can be found? (The sides
- of the batteries mention that they are NiCad, but even if they are
- rechargeable, they cannot obviously be recharged while permanently
- connected to the PCB.)
-
- And once they're removed, and replaced with fresh batteries located
- away from the PCB, if I remember correctly, isn't there more than
- just the system clock that needs to be reset? I think there is
- supposed to be a program called SCRAM available from the Fred Fish
- archive which will read your static column ram settings for SCSI
- config and some other things; I think these settings are battery
- backed in an A3000 and are the closest equivalent the A3000 has
- to a CMOS setup? If I obtain SCRAM, copy down all the settings,
- and then plug them back in after the battery replacement, will I
- be okay? Is there anything more that would need to be done?
-
- Also, is there anything more being backed up by the battery in
- the bridgeboard than just the bridgeboard's system clock and
- the settings that are visible when you call up the Commodore
- setup utility as discussed in the manual? If I copy down all
- settings from the Commodore Bridgeboard Setup, and reset the
- system clock, will I be fully restored, or is there more?
-
- I'm surprised there isn't more discussion on this. It's the
- lurking timebomb inside every battery backed Amiga, and on
- every bridgeboard, and a solution has to be found.
