Do 3rd Party or Generic Batteries charge in the camcorder

[Gr8Believer]

Just wanted to confirm if generic batteries charge in the camera or do I have to buy a seperate charger for it

As long as they use the Inteligence System, the answer is yes. I got mine from vhbw-tec on Ebay.

What model number did you get?

[VideoGeek]

I have used Watson batteries and they work well.  They will charge on the camcorder.  

Watson BP-808

Watson BP-819

Watson BP-827

Wasabi is another brand I use and trust.

These batteries seem to be for Canon HF S20. Do they fit in the Canon HF G40?

[VideoGeek]

Those work for the HF-G20.  The Watson ones for the G40 are the BP-820 and BP-828.
