Two-Pack Replacement Battery

This Kastar two-pack supplies two lithium-ion cells rated at 3.7 V and 1300 mAh each, delivering 4.81 Wh per battery. They are built as direct replacements for the Sony NP-FT1 Type T battery used in a range of Cyber-shot compact cameras. Integrated protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating.

Upgrades From Worn Originals

The pack replaces ageing or lost Sony NP-FT1 cells and works with the original Sony BC-CS3 and BC-TR1 chargers. Swapping to fresh units is worthwhile when the original battery no longer holds a full day’s charge or when a spare is needed for extended shooting sessions. The cells meet UL1642 and CE safety standards for reliable operation.

Suits Cyber-Shot Owners Needing Spares

Photographers using compatible Sony Cyber-shot models such as the DSC-T, DSC-L1 or DSC-M series will appreciate the ready spare and longer run time. Users whose cameras require a different battery form factor or voltage should look at other options, as these cells only fit the NP-FT1 footprint.

Questions about this item

Will the 3.7 V NP-FT1 pack slide into my Cyber-shot DSC-T33 battery compartment?

Yes, the NP-FT1 is listed as compatible with the DSC-T33 and other T-series models, so it fits the same slot as the original Sony pack.

What is the correct way to insert the battery into the charger so the contacts align?

Match the three gold contacts on the battery to the corresponding pins in the BC-TR1 or BC-CS3 charger; forcing it backwards bends the pins and prevents charging.

How many charge cycles can the 1300 mAh cells deliver before capacity drops noticeably?

The cells meet UL 1642 and CE safety standards with built-in protection circuits, which helps maintain cycle life, though exact cycle count varies with usage and storage conditions.
