strange reboot problem

[maddog241]

Greetings to all...
I recently had to replace my original HTC battery that came with my XV-6800. I also have a standard Seidio battery and charger which I use. I use the Seidio charger to charge whichever battery happens to be the spare at the moment and I swap them as needed. Last night when I pulled the dying Seidio battery out and put the stock HTC battery in, each time I slid the keyboard open or closed, the phone would shut off and reboot. I put the dying Seidio battery back in and the phone was fine. As soon as I put the HTC battery back in, the problem occurred.

So, the HTC battery is bad???? That was my first thought....But maybe not. Today after the HTC battery was in overnight, I can not reproduce the problem. The battery is at 64% currently and is showing 3.871 V. as reported by Batti 2.4. Last night it was 100% and 4.4V.

I was wondering if anyone knew of the voltage tolerance + or - from the 3.7 V the batteries are rated? Could the battery have been overcharged by the Seidio charger?

Has anyone else seen or heard of this problem?
