I have an RCA CC850 camcorder with rechargeable batteries but it s missing a battery charger. Where could I get a charger for the batteries?

boh.............. 

Try looking on eBay.

Don't buy the first charger you see unless it's really good and really inexpensive.

The old battery isn't going to be any good any more, so you'll need a new one.

That could be difficult to find and rather costly no matter where you get it.

if the battery is really old its doubtful it will have much performance as a disclaimer ... but, if it has a charge port you can match a plug with, a hobby type charger for models is fully adjustable and can charge literally anything once you make a lead up .. something like a turnigy from hobbyking .. im sure you could pick one up for under 20, then just set it to nicad most likely, whatever your battery is .. and the current to .5 amp or so will do it, i wouldnt go higher ..

It's a dinosaur, so eBay would be the most likely source.

you might be able to find one on amazon since they sell everything
