I recently found a 1200 mAh battery on Ebay for the DC600. I can't seem to find that high of capacity battery anywhere else which leads me to ask if they are really 1200 mAh? I'm sure it is an aftermarket battery. What is the largest battery (mAh) Sealife currently offers? They appear to be half the price as some of the other web stores (Buy it now for $12.98). Reputable web stores offer anything from 650-800 mAh's as far as I can find. As with all others who dive and take many pictures with the DC600, I am looking for longer battery life. Upcoming diving trip needs insurance that my camera can continually run. Any help and info. would be greatly appreciated.
