Query: Panasonic 6-Volt Photo Lithium Cylinder Battery (2CR5MPA1B) (2CR-5MPA1B)

Purchased this battery for use in a Canon EOS 630 camera. The battery was received promptly and fully charged according to my Camera's built in battery checker.This battery has been installed for nearly a month and a half now and I have gone through 6-24exp rolls of film and thus far my Camera is still indicating full charge for the battery, so I suspect I'll get average to better than average life expectancy for the battery.Considering I paid $10. less for this battery than I can find it for locally retail, I believe it to be a bargain and would not hesitate to recommend to others.
