Replacement battery for the 720 rev 1

I got mine here:

$16, free shipping, and a set of tools as well. Ordered on Thursday, had it on Monday. There's a video here that shows how to do the job but their price for the battery is high and they charge you for a tool kit:

Wherever you buy the battery, be sure to get the tool kit unless you happen to own a T5 torx driver. The job is very easy to do if you're at all handy with small tools. Takes about 30 - 45 minutes. Be sure you remove the SD card or the dummy before trying to separate the screen from the body.

I charged the battery for about 2 1/2 hours, removed the 720 from the cradle and turned it on. It operated for 3 hrs. and 15 mins. before the battery indicator started blinking. I shut it off and put it back on the cradle. After 2 hrs. the battery indicator showed almost fully charged. I left it charge over night. I turned it on and this time the battery lasted 3 hrs. and 30 mins. before the indicator started blinking. I let it run until it went into auto shut-off which took about 5 more mins.

If your unit shuts down after 5 - 30 mins when running on battery (like mine did) and it's about 2 -1/2 years old, you probably need a new battery.

Good luck, Jim
