First, you should be sure that it is a battery acid problem or capacitor, there is one (C192) near the chip U891 in charge of the ram....
If it is, it's highly possible that your ram problem is related to that.
Take a good picture of the battery area and post it here if you are not sure.
We will be able to tell you if the battery is faulty... A very small battery leak can cause big trouble if it is not good cleaned...
You could also try with a knowing working set of ram if no leak is detected and check continuity with a multimeter to find an open track.
