Four-battery kit for Sony Cyber-shot cameras

This set includes four lithium-ion replacements for the Sony NP-BN1 Type N cell and a matching AC wall charger. Each battery delivers 3.7 V and 1500 mAh capacity, suited for the long list of Cyber-shot models from the DSC-J10 through the DSC-W730 series. Photographers who carry a spare for every shooting day can keep all four cells topped up from one outlet. It does not serve cameras that require a different battery form factor or voltage.

Wall charger with foldable pins and LED status

The supplied charger accepts 100–240 V AC input and provides 4.2 V at 600 mA DC output for each cell. A red LED shows active charging while a green LED signals standby or full charge. The foldable flat plug reduces bulk in a bag and eliminates protruding pins during storage. No active cooling is used, so operation stays silent in quiet environments. Buyers needing simultaneous multi-bay charging beyond one cell at a time will find this unit limited.

Compact lithium-ion cells

Each battery measures 3 by 2 by 3 inches and weighs 5.55 Wh, matching the original Type N footprint for direct insertion into the listed Cyber-shot bodies. The lithium-ion chemistry avoids memory effect and supports repeated partial recharges without capacity loss. The charger’s fixed 600 mA rate means a full cycle takes several hours, so users planning rapid turnaround between shoots should plan accordingly. Cameras outside the compatibility list cannot use these cells.

Questions about this item

How do I insert the Kastar NP-BN1 batteries into the AC wall charger?

Align each 1500mAh battery with the charger slots matching the 3.7V contacts; the foldable flat plug folds down for wall outlet insertion.

When will the four Li-Ion batteries need replacement?

Replace the 5.55 Wh packs when they no longer hold a full charge after the LED shows green at the 4.2V 600mA output.

What limits continuous charging of all four batteries?

The charger outputs 600mA total, so charging four 1500mAh cells sequentially takes longer than a single battery cycle.
