The battery of my old Apollo 1240 accelerator has been dead for a long time now, and I want to replace it with a new one. So I'm wondering about what type of battery I should buy?
A while ago I bought a second Apollo 1240 which I now use in my main A1200 instead of the old one. This card already had the battery replaced with a 3V VL2020 battery, so I wonder if this is the right one? By doing a quick search on Ebay I found some of these batteries, but they seem to be for BMW keys, and this puzzles me a bit.
I also want to replace the fan on my old Apollo, so does anybody have any recommandations about what type of fan I should buy? And what type of glue should I use for attaching it to the CPU?

The apollo 040/40 i had used a rechargeable batt that can leak and eat the accelerator.remove it asap if you do nothing else. more than likely someone did a coin cell hack to your other one. You should use a diode if you do this,since lithium coin cells shouldnt be recharged.

Look here:

I'm using Panasonic VL2020 accumulator. This accumulator is really very nice - it will not leak and it will be re-charged during normal Amiga operation.

I've used my apollo 040 40mhz without fan years. It has double size compared to cpu cooler element from old nvidia craphicks card. Only clue I use with it therman grease, so it can be easily removed and replaced. This solution requires tower

It doesn't look like my Apollo has suffered from battery leakage, but I will of course have to inspect things more closely after removing the old battery. The type of battery is the same as the one featured on this card: http://www.amiga-hardware.com/display_photos/apollo1240_3_sm.jpg. I removed the plastic cap, and it certainly looks like the battery have started to leak, so removing it has top priority right now.
The previous owner of my new Apollo card haven't used a diode with the battery since the VL2020 is actually rechargeable.

Yes, I think I'll buy a VL2020 then :)
I have looked at your pictures, and I'm a bit curious about the small card that sits next to the CPU, what does it do? Is it a kind of voltage regulator or something?
Another thing, is it a laptop CPU fan you have mounted on the processor?

I must say that I'm a bit sceptical to fanless solutions. Another thing is that I have plans of using my old Apollo in a custom made cabinet I have made, and I don't think a cooler element will fit in there, unless it's a small one that is.
BTW. Thanks for the replies everybody :)

First answer: this small board is 3,3V regulator necessary for 060 CPU
Second answer: no, this heatsink+fan is not form laptop, but you can use any fan to cool down CPU. Your imagination is only limitation here. ;-)

Ah! so you have upgraded from 040 to 060 CPU on the card then :)
Regarding a fan, my biggest concern is the voltage, do you know how many volts that is output for the fan? I don't have the tools required for checking this out right now.
-
That's depend on fan you are going to use.
You can connect fan to +12V, +5V or +3,3V.
Last solution is not recommended, but technically possible.

I don't think I was clear enough with what I meant :)
On the Apollo card the wires from the fan are soldered to some solder pads, how many volts are output from these pads?

You can always check this by using multimeter, but it's 12V (12V is also written on PCB, please look closer). ;)

OK, thanks a lot stachu100. :)
