Hey all, since batteries can be quite an expense, I thought people might be interested in my experience with Hahnel's alternatives to the BP-A30 battery (C70, C300, etc.).
I've had one Canon BP-A30 and two Hahnel HL-A30s, and I've been using them, pretty heavily, in rotation, since May, in my C70. I'm really pleased with all of them.
Of course the test is how well they work, and particularly after some use. So, 6 months in, I ran tests on the Canon and one of the Hahnels. The results (just recording continuously in front of the TV, 4k, long GOP, 23.98 FPS):
Canon BP-A30: 3h 02m 20s.
Hahnel HL-A30: 2h 57m 14s.
So pretty much the same. Given the price difference, I'd have to say the Hahnels are good value.
Hope this helps.
