Questions about this item

How long will the 770 mAh capacity last in a Sony Cyber-shot DSC-W370?

The 3.7 V 770 mAh lithium-ion cell matches the original NP-BK1 rating, so it delivers the same shot count and video time as the factory battery in that camera.

Does this battery use the same connector and charging protocol as the NP-BK1?

Yes, it is built to the NP-BK1 / NP-FK1 form factor and charges in the original Sony charger or in-camera via USB without any adapter.

Will the 40.10 x 34.10 x 6.80 mm dimensions fit the battery compartment of a DSC-W180?

The cell matches the exact NP-BK1 footprint, so it slides into the DSC-W180, DSC-W190, DSC-S950, DSC-S980 and Webbie models without forcing the door.
