First, Hello to all...first day at Pixalo. Seems like a nice community.
My first question is probably very basic to most of you but I'm stumped.

I have a 550 EX. I purchased it a few years ago but only used it once as I left the batteries in the body and it corroded the metal inside. Since it was my error I didn't feel right trying to exchange it.

I just noticed that there's a Canon CP-E2 BATTERY PACK. My Question:
Will this help me? Can I use it to bypass the corroded battery compartment of the 550?

Thanks?
