The middle connection is most likely a temperature tripped reed switch to shut down the charger when the battery gets warm. Charge with the + & - contacts with about 1 amp for about 1 hour. To get that from say the 12 volts from your truck, use in series a 5 ohm 10 watt resistor which is going to get pretty hot. When the battery starts to get warm, it is fully charged. Maybe you can find a wall transformer that will put out 1 amp at 7.5v to 8 vdc.

lithium ion batteries require a very special charging device. output is modulated in relation to temperature and/or charge time or something like that. i wouldnt try to rig something up as those suckers are expensive!

I've bought chargers for my Sony batteries on Ebay for 10 bucks. What battery number is it (NP-***)?

Forgive me for sounding extremely obvious, but I take it you don't have AC adapter that came with the camera? Because the cord will charge the battery while it's in the camera.

Also, I am not positive, but I think the center pin is used on the info lithium batteries. It tells the camera how much battery life you have IIRC.

If you want, I can look at my cord for my camera tonight and tell you the output. I have a DCR-TRV-18 that uses the NP-FM50 battery as well.
