Hey guys, just wondering if there is any difference between the 2 batteries. My dad has the rogers V3 and it says 3.6V but I have the Telus V3c and it says 3.7V. They both have SNN5696, again rogers is SNN5696B and Telus is SNN5696C??

So are they compatible? I wanted to get an extra battery for me and my Dad off of Ebay and its cheaper to buy more then one from the same seller but I can't seem to find a seller that sells both batteries.

Thanks for the help,
