Pokemon Gold/Silver/Crystal game clock battery

Hi where can I get a replacement for my internal Pokemon Game Clock batteries for Pokemon Gold/Silver/Crystal? My saved game files keep corrupting!!!
***Edit**
This thread is not about the "Battery ran dry" glitch in Pokemon Ruby/Sapphire.

A place where you can get a new cart, obviously. Save game files that are corrupted, just get a new cart.

Although that might be hard seeing as there aren't a lot of carts around anymore ;-;

is there any way to replace batteries for the internal clock? OR can you only buy a new game which none exist anymore...only used ones which are probably also losing time... this worries me. How long should the timer last approx?

I've had mine for five years now and my clock is now slow by about 10 minutes. I really don't play that often anymore and occasionally check on it.. supposedly the average life of a cart battery should be from about 3-6 years.
