"Visiontac v-900" GPS Data Logger (HD)

I've had two of these so far. The first one, I lost after I accidentally left it on the roof of my car and drove away. I'm still using the second one ... but, after leaving the 12DC plugged into the unit to use the "Auto ON/OFF" feature for several weeks straight, the case expanded rapidly (not quite an explosion) and can't be closed. It's still functional, but for how long? Who knows.

ABSOLUTELY ZERO response for support from either the merchant or the manufacturer. No replies to emails.

How many hours does the battery last? I know it says 20-24 hours, but I expect it to be less with actual use.
