How to Charge Batteries off of a 12V I have an assignment in the artic circle this march and will only have access to a 12V snowmobile battery to charge my camera batteries off of. The cold is a factor so I will be going through batteries fast. What sort of adaptor/equipment will I need?

Power inverter..rated at least 2 amps continuous duty cycle. Plug your AC charger into the power inverter. Inverters convert DC to AC. If that won't work for you, you can always charge your batteries at their rated voltage (-20%) with unfiltered (rectified but not smoothed) DC.

Before you take off Derek, you should learn how to spell "Arctic". Somehow I'm having trouble believing anyone would give an assignment like that to someone who doesn't know what equipment to pack. This one doesn't pass the smell test. And why you'd be asking us rather than the manufacturers is somewhat beyond me. But seriously folks, the best solution perhaps is a fully manual camera and a crate of film.

And don't forget to pack your Long Johns, Derek, to keep your 'batteries' warm... It can be this ––––––––––––– cold up there, you know!

'Assignment' doesn't necessarily mean photo assignment. Maybe the guy got a job working on the North Slope in the oilfield, and wants to bring his camera. Maybe he got a job with a scientific survey group. Maybe he's going to be living with Eskimoes. Whatever... it's a bit silly to assume that his primary purpose for going up there is photography. The inverter idea is a good one... simple and it works, but it's not the most efficient way. However, unless there's a 12v auto lighter charger for your battery, it's about the only sure way to charge. I think the 'rated voltage' approach will only bring batteries up to between 80 and 90 percent... and if you make a mistake you'll fry your batteries.
