That card with the battery is a Commodore-Amiga A501 512kb RAM expansion card clone.  It upgrades the A500 to 1MB RAM.  It also has a RTC clock and battery to save the time.  These are prone to leaking and damaging the RAM card!  This issue also happens on the A500+ (which has this RAM card and battery built into it) along with the A2000/3000 and 4000's.  Remove the battery, clean the area with lemon juice and clean off with isopropyl alcohol and let dry. You can then either leave battery off (no need for battery unless you want to timestamp your files!), or install a NiMh 3.6V battery in its place.

it cost like $20 to $50 for a new replacement card, and most have the battery still on and leaking.  So if it works, definitely it is cheaper to repair this one!


Here are the new NiMh direct replacements:

Amigakit has coin cell adapters for sale, they work great!  No leaks either:

Fire up SysInfo if you can to see if it detects a Clock battery.  The card could be damaged but still work as a RAM card.  Whats interesting with it is there are empty sockets...  Does it report 512k as fast ram?
