Kastar NP-BN1 Two-Battery Kit

This kit supplies two lithium-ion cells rated at 1500 mAh and 3.7 V each, plus a compact AC wall charger with a foldable flat plug. It is built for owners of Sony Cyber-shot models such as the TX100V, TX200V and the W310, W320, W330, W350 series who need reliable spare power for everyday shooting.

Sustained Charging Behaviour

The charger accepts 100 to 240 V input and delivers a steady 4.2 V at 600 mA output, so each cell reaches full capacity without a rapid burst that could stress the chemistry. A red LED shows active charging and switches to green when the battery is ready or on standby, giving a clear visual cue during longer top-up sessions.

Replaces Original NP-BN1 Packs

The set directly substitutes Sony NP-BN1 Type N batteries and works with BC-CSN or BC-CSNB chargers, covering cameras from the DSC-J10 up through the DSC-W730 range. Photographers who carry a single original cell gain a practical upgrade for all-day events, while users with ageing packs that no longer hold a full 5.55 Wh charge restore dependable run time.

Questions about this item

Does the AC wall charger run hot or make any noise when left plugged in all day?

The charger draws AC 100-240V at 50-60Hz and outputs a steady DC 4.2V at 600mA with no moving parts, so it stays cool and silent during continuous use.

What must I already own to charge these NP-BN1 batteries with the included wall charger?

You only need a standard mains socket; the charger has a foldable flat plug that accepts 100-240V input and delivers 4.2V 600mA directly to the two supplied 1500mAh Li-Ion cells.

Will these 3.7V 1500mAh batteries work reliably in my older Cyber-shot DSC-W310 that originally used the NP-BN1?

Yes, they match the original NP-BN1 specification of 3.7V and 1500mAh, so the DSC-W310 will recognise them and report capacity normally.
