You need military spec or non military spec? :-D

(edit:  seriously 'tho, what model battery do you need?  Heck, somebody could just drop one in the mail for you if you wanted)

Ummm...military spec of course, I want my A2000 to outlive me.  :-D

I can get the Varta replacement batteries here in Canada locally but they cost $17 plus tax which isn't cheap. So I'm sure you should be able to get them from your local electronics dealer where you live.
I'd call a few shops in your area and compare prices.

To adz:

Just solder a red wire and a black wire to the motherboard, where the battery use to be.  Drill a hole in one of the rear slot covers for a mono sub-mini  jack.  Then mount the jack onto that cover.  Next solder the other ends of the red and black wires to the jack.  Get a 3-AA battery holder and solder on a mono sub-mini plug to the wires coming out of the battery holder.  Install the batteries and plug it in.  The batteries should last about one year.  The battery holder sits behide your Amiga 2000, so it is not seen.  This is how I have mine set up.  It works great and you do not have to worry about battery-acid leakage because the 3 AA batteries sit outside your Amiga.  I got the idea from my Atari Mega ST4.  It takes only 2 AA batteries for it's clock (3 volts), but the Amiga 2000 takes 3 AA batteries (4.5 volts).  IMPORTANT:  When you solder the red wire to the positive pad on the motherboard, make sure that the temperature of your iron is NOT hotter then 650F and that you do NOT leave the iron on that solder-pad for more then 4 seconds.  The positive solder-pad for the battery is very small and is easily burned off if you are not careful.  When you solder the black wire to the ground-plain on the motherboard, you may have to increase the temperature of the iron to 800F to 1000F in order to get the solder to flow properly.  Do not leave the iron on the ground-plain for more then 10 seconds.  If you do, the ground plain may bubble or discolor.  I hope that I have helped you, adz.     :-D

Here's a battery install method for you.   :-o

Adam,
According to the manual, that's a 3.6V 60mAh Nicad battery.  I think I'd avoid getting anything much larger to avoid damaging the charging circuitry in the Amiga.  Oh yeah, a neater way to mount a replacement battery off-board is to run the wires through one of the vent holes in the metal front of the 2000 frame. (after removing the case top) just stick the battery to the frame with velcro. The top cover hides the hack neatly. :-)

Hi JimS,

Some of the original batteries actually have 4.5 volts printed on them.  I do not think that a .9 volt difference is going to "damage the charging circuitry".  I do like your version of the mod though.  That is how I use to do it on the old IBM XT computers.     :-D
