Like many other Palm Treo owners who are trying to get through the day without constantly recharging, I found that the stock 1800mAh battery was not lasting nearly as long as I needed. The first solution I tried was the Seidio 2400mAh extended battery ($39.95), which helped a lot during regular daily usage.

But once I got a hosted exchange account – and discovered the battery drain that is push email, I quickly learned that even the extended battery was not quite enough. Enter the Seidio 3200mAh Ultra Extended battery ($54.95), a battery that offers nearly double the original’s power.

Obviously the 3200nAh battery is larger than both the original and 2400mAh extended batteries, so it comes with a replacement compartment door.

Besides the added battery life, the next coolest feature of this replacement battery and door is that Seidio drilled a hole into the precise spot needed to access the reset button without removing the battery compartment door. Brilliant!

The rectangular hunchback now present on the Treo takes some getting used to, but it’s mot too strange.

If you don’t need the 3200mAh or don’t want the bother of an extra bulge that may or may not fit in your favorite Treo case, do take a look at the 2400mAh extended battery. It fits behind the original door, and you can even take a Dremel tool to the OEM battery compartment cover if you want the same reset button ease of access.

But just in case you don’t feel confident enough to attack your cover with a drill, there is also an available Seidio battery cover with reset hole.
