Re: How important is the third pin on a charger?
Don't ake my word for this, but my boss tells that the midle pin is a communication pin used to give the camera the information it needs to calculate how long the batteri will last.

RE: How important is the third pin on a charger?
Larry, I think you just need to get a car power inverter so you can plug your regular charger into your car. I don't trust third-party chargers to do it right and not damage expensive batteries.

RE: How important is the third pin on a charger?
Well, I used to sell Promaster universal chargers back at my camera shop job. You may want to check and see if any of their current chargers support the K-5 battery. They make good products, for the most part. Pretty reliable. http://www.promaster.com/products/products.asp?CatID=50&SubCatID=8&sm=sm2_508 John -- http://www.jacelio.com Original Message Subject: Re: How important is the third pin on a charger?
