Sony NP-4500 Rechargeable Battery Pack

The 4500mAh rating means I can shoot all day without scrambling for a wall outlet, and the InfoLITHIUM chip keeps the power meter honest till the last minute. It's a pricey spare, but the peace of mind on a long travel shoot is worth every cent.

Finally got a full afternoon of filming on one charge with this 4500mAh pack—the InfoLITHIUM tech really keeps the camcorder running smoothly without that sudden power loss.

My old battery would die mid-family picnic every time, but this one holds a solid 6.0V charge for hours of recording without a hiccup. It’s a relief to finally have a spare that doesn’t quit on me.
