Kastar NP-BN1 2-Pack Battery Kit

Two lithium-ion batteries and a foldable AC wall charger replace Sony NP-BN1 cells for Cyber-shot DSC-QX100, DSC-T99, DSC-T110, DSC-TF1, DSC-TX5 and DSC-TX7 cameras. Photographers carrying a compact Sony model gain a spare pair for long shooting days.

Charger Thermals and Power Draw

The wall unit accepts AC 100–240 V at 50–60 Hz and delivers DC 4.2 V at 600 mA. A red LED shows active charging; green signals standby or full charge. The foldable flat plug keeps the adapter cool and quiet during typical overnight use.

Upgrade From Single OEM Cell

Swapping a lone original battery for this twin-pack doubles runtime without changing camera handling. The jump is worth it when a day of travel or video recording exceeds one 5.55 Wh cell, yet the charger still fits a small bag.

Questions about this item

How do I install the Kastar NP-BN1 batteries and what step is often missed?

Insert each 1500mAh Li-Ion cell into the camera battery compartment following the polarity markings, then close the latch fully so the contacts seat; the step people miss is not locking the latch, which leaves the pack loose and the camera will not power on.

What maintenance or replacement will the NP-BN1 pack need later?

The two 3.7V 1500mAh batteries will gradually hold less charge; after several hundred cycles replace them when run-time drops below your needs — the AC wall charger with foldable flat plug and 4.2V 600mA output remains usable for future NP-BN1 cells.

What limit appears first during sustained charging of both NP-BN1 batteries?

The charger delivers 4.2V at 600mA, so charging two 5.55 Wh packs sequentially takes several hours; the current limit is the first bottleneck, not heat or voltage range.
