On the card in slot 2 is a barrel shaped NiCad battery. The purpose of the battery is to keep the real time clock (RTC) going when the computer is powered off.
One of the photos suggests to me that it is leaking. If it is leaking, then you need to deal with that before the leakage causes damage. There may already be some damage. After the battery is removed, the suggested (by Druid6900) method of neutralising the NiCad leakage on the card is by the use of vinegar and water.
The computer can function without the battery. Without it, the date/time will be lost when the computer is powered off.
