Spare Battery/Replacement T2i/550D?

[AllAroundFilmLV]

I'm looking for a couple spare batteries. I've seen Canon brand on Amazon for around $40. But I've also seen a few with the same mAh for around $10.

What/where did you decide to purchase as a spare battery?

What would you guys suggest as a battery replacement?

Would you suggest an off brand battery? I'm also skeptical of these one offs rogar-Mark-01(DBG).

I bought some off brand ones for $12/pair on Amazon and haven't had one issue yet - I haven't done more than a few full days of extensive shooting though but they have held up very well in every situation so far
