At the risk of sounding stupid

[spacejam0]

A really stupid question. Are there any batteries that need to be changed on a Capcom board or on an older Williams board?
I cant see any batteries at all on the Capcom board and I can only see one of those flat lithium cell button batteries in the Williams board which I'm not sure if I need to worry about changing or not?
Are the batteries hidden somewhere else or don't they use them and do button lithium cell batteries need to be changed?
Cheers
Tim

 Capcom used a RAM chip with a built in battery, so no to that.

Older Williams would normally have 3 aa batteries unless modified as this  board seems to be.

Thanks Nick would seem I have nothing to worry about then

The lithium battery in the flash will last 3-5 years - if not more. They don't leak.
