Would appreciate the addition of a battery number in the description.
Searching for the battery was simple, as was the purchase. The only thing missing, which would have reassured me that I was purchasing the correct battery, was if the battery number itself was available on the website. For example, I know I am looking for battery #511-A for my Eos 30D. Having that cross-check would give me the confidence that I didn't just spend $21 on a battery that is going to be the wrong size.
