Cave PCB Batteries - worth replacing?

[jase]

Hi

I've heard reports of people changing the batteries on their Cave PCB's due to the original battery being prone to leakage. Im just wondering whether it would be a good idea to renew the batteries to prevent future battery leakage/board damage.

Has anyone come across this? Are the batteries the same on all the boards? Does this even apply to newer boards like Mushihime-sama Futari and Dodonpachi Daifukkatsu?

Any advice/thoughts on this would be very much appreciated!

Thanks
Jason
