Four-pack lithium-ion camera batteries

The Kastar NP-FT1 set supplies four 3.7 V 1300 mAh lithium-ion cells rated at 4.81 Wh each. They are direct replacements for the Sony NP-FT1 and Type T batteries used across a long list of Cyber-shot models including the DSC-T10, T10/B, T10/P, T10/W, T11 and T33. Photographers who want spare power for extended shoots or travel can carry the whole pack without relying on a single cell.

Thermal behaviour and power draw

Each cell carries built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection circuits that meet UL1642 and CE safety standards. The chemistry runs cool during normal camera operation and the protection logic limits current spikes so the battery does not overheat or drain unexpectedly. No active cooling or special charging routine is required beyond the standard Sony BC-CS3 or BC-TR1 chargers.

Build integration and what it frees

The four batteries slip into the existing battery compartment of every compatible Cyber-shot camera without adapters or modifications. They also fit the original Sony chargers so no new charging hardware is needed. Carrying the full set removes the need to hunt for a wall outlet mid-session and frees the photographer from rationing shots on a single charge. Buyers who need higher capacity cells or a different form factor will not be served by this pack.

Questions about this item

How do I install the Kastar NP-FT1 batteries in my Sony Cyber-shot DSC-T10, and what step do people often miss?

Open the battery compartment, align the contacts with the camera terminals, and slide the battery in until it clicks; the step often missed is fully seating the battery so the latch engages securely.

What maintenance or replacement will these 1300mAh Li-Ion batteries need over time?

Expect capacity to fade after several hundred charge cycles; store at about half charge in a cool place when not in use and replace the pack when run time drops below your needs.

What limit appears first during sustained shooting with these 3.7V batteries?

The 4.81 Wh capacity determines how many shots you get per charge; continuous use will drain the pack before thermal protection activates.
