Canon LP-E19 Battery Pack

Swapped this into my 1D X Mark II and immediately noticed it lasts noticeably longer than my older batteries during back-to-back event coverage. That extra 10% capacity really makes a difference when you're shooting all day without a chance to recharge.

Was charging up before a long shoot and noticed this pack holds noticeably more juice than my previous one — that extra 10% capacity really comes through during back-to-back events. The 2750 mAh rating means I get through a full day without scrambling for a charger, which is exactly what I needed.

Swapping out my old battery for this 2750 mAh pack meant I shot a full wedding without even thinking about recharging, and it holds the charge beautifully when sitting for weeks. The 10% capacity bump over the previous version makes a real difference on long shoots.
