Need a 1d mk II N battery. Which brands

I have only used the canon brand batteries in my mk II n but I know there are other alternatives out there. Are there any other good brands out there i should take a look at?

Thanks all.

Ever consider rebuilding your current ones? As crazy as it sounds, I'm working on replacing my cells with quality 2000mAh Eneloops in hopes of getting reliable cold-weather performance -- I should have it done late next week.

Black Diamond has a pretty good rep around here.

Why not stick with original Canon though? You can be assured that the fit will be 100% and you'll maintain weathersealing.

I tried some off-brand batteries and actually went through three of them. Not one of them fit right.

The one i am replacing has a cracked casing. So i need a new battery. Ill probably just pick up the canon.
