The one thing I missed when I switched from my Treo 650 to 750 was the battery capacity. I missed being able to go through out the day not worrying about my battery. I miss the days when I would be able travel without having to worry if I packed my charger. I love my Treo but hate the original battery capacity and felt all hope was lost. I felt I would be tied to a charger and worries about outlets for the rest of my mobile days. Sure there were other batteries, but they were all too big. Some so big you had to buy a new a whole new back case. It was hopeless…until now. Seidio has just released the 1600mAh OEM SIZED EXTENDED BATTERY FOR TREO 680/750. This bad boy does two things.
