- Yes, that's the best way to replace the battery.

- Dunno about A2386SX but it is enough for the A3000 motherboard.

-
- Doesn't matter. You need a 3.6V rechargable NiCD battery. You can
- by a standard battery holder box and use 3 standard cells of 1.2V each.

-
- Sorry, no. They are rechargable and _are_ recharged automatically
- whenever the Amiga is turned on. If they weren't recharged they
- would be empty after a few months.
-
- Since they are recharged it might be a bad idea to use a non-rechargable
- battery.

-
- You mixed things up. Static column ram is (possibly) your main memory
- and it is not battery backed-up :)
-
- To set the CMOS setup you can use a tool like SetBattMem.

-
- It _is_ a CMOS setup just in the way clones store their BIOS and chipset
- parameters. It is just used for a few things though.

-
- You are probably okay without any precautions. It is unlikely that
- the old contents is lost but still recognized as valid. And the
- default settings are what probably have now (otherwise you would
- already have a SetBattMem tool or something equivalent).
-

-
- AFAIK not.
-

-
- Should be everything.

-
- As lurking as in most PCs.
