I have an un opened a500 that's works perfect but I'm considering opening her up and removing the battery before it fails.
What do you guys think? Is this what you do?
I'm lothed to open her up really but I'm thinking it's better than it leak and eat the pcb.
First of all remove the trapdoor cover and remove any memory expansion. If there is a battery on that then remove it. If there is a battery here then it's less likely that there is one on the motherboard, but it is possible so you should check anyway.
Now you have nothing in the trapdoor slot you should use software that detects if you have a real time clock (I think sysinfo does, setclock probably is another way to check).
If you don't have a real time clock then you don't have a battery. If you do still have a real time clock with nothing in the trapdoor then yes you should remove the battery (the cr2032 batteries from amigakit are good replacements).
Only the revision 8 a500+ motherboard had the space for a battery, AFAIK they only turned up in a500 cases in countries that didn't get an a500+ launch. The manufacture date on the sticker on the bottom may give an indication of what revision it is. From memory rev 5 was 1989, rev 6 was 1990, rev 8 was 1991 (although take that with a pinch of salt).
