DESC: Keep your DSC-T7 Digital Camera charged while on the move with the NP-FE1 rechargeable battery pack from Sony. With 450 mAh storage capacity and InfoLithium® technology, it provides long battery life and consistent power. The InfoLithium technology also eliminates the “memory effect” you find in most rechargeable batteries, so you can charge at any time, regardless of the amount of power remaining.
