A3000 battery

[SpeedGeek]

I'm not worried about my replacement battery leaking because it's sealed in shrink wrap. The A3000 will boot using default SCSI settings without a battery but if you want to use synchronous mode or need the long SCSI time out you need a battery! Also, certain disk utilities will report an error if you have files newer than the boot drive creation date.

You don't need the battery for "SpeedRamsey" you just need Ramsey 07, but if you have fast enough memory you can just set the Ramsey Speed jumper to 16 MHz.

You also need the battery to enable LUNs (SCSI card reader, etc.).  Can't boot to my CF card without LUNs enabled.
 
I don't think that shrink wrap will stop battery leakage, but I'm no expert.

That's interesting that you need LUNs enabled to use a CF card. I would ask mechy if he knows how to configure your SCSI/CF adapter to work without LUN's enabled.

I don't expect the shrink wrap to stop battery leakage. It just expect it to contain it enough to prevent damage to the motherboard.

Also, since I don't need a diode I can expect the RTC/memory to run a lot longer than with the coin battery hack. The rechargeable battery charges to approx. 4 volts and has > 100x the current capacity of a coin battery.

the pcd-50B scsi card readers are hard wired with pcmcia slot as lun 0.. so you can use that slot with a pcmcia adapter and cf card and not use luns, you simply will not have access to the other slots like cf,sd/mmc,smart media,and sony memstik which is ok if you just want a cf for a HD.
having the other slots hot swappable can be handy.

I have coin cells going on 5 years and still working btw. the LIR2032 should go way longer before voltage drops too low.

I feel you guys should quit recommending batteries that can leak when we have a better solution,haven't we lost enough nice amigas? i'm tired of fixing battery damaged traces

The problem is that it takes longer for the scsi.device to scan LUN's so the time you could save booting from CF is negated by the LUN scan. You can set LAST_LUN flag on RDB after CF drive is found but a cold boot will cause all LUN's to be rescanned if LUN's are enabled.

I didn't recommend a battery that would leak on the motherboard. The double sided adhesive tape is an extra barrier in addition to the shrink wrap. I simply offered an alternative solution. FYI coin batteries are not leak proof either. My ex's calculator had 2 which died, leaked and corroded the battery terminals. I didn't like fixing that very much either!
