What this battery replaces

This Kastar NP-FT1 lithium-ion cell is a direct replacement for the Sony NP-FT1 Type T battery used in Cyber-shot DSC-L1, DSC-M1, DSC-M2 and DSC-T series cameras. It supplies 3.7 V and 1300 mAh capacity so photographers can keep shooting without carrying the original Sony pack. The single-cell pack fits the same battery compartment and works with Sony BC-CS3 and BC-TR1 chargers.

Thermals and safety in use

Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating during normal operation. The cell meets UL1642 and CE safety standards, so it runs at the expected temperature for a 4.81 Wh lithium-ion pack without extra cooling. No fan or active thermal management is required.

Capacity that decides fit

The 4.81 Wh rating determines how many shots or minutes of video you get per charge compared with the original Sony battery. If your workflow demands more energy than this single pack delivers, you will need to carry spares or choose a higher-capacity alternative.

Questions about this item

How do I install the NP-FT1 battery in my Sony Cyber-shot DSC-T10, and what is the common mistake?

Slide the battery into the compartment with the contacts facing the camera body until the latch clicks. The step people get wrong is inserting it upside down, which prevents the contacts from aligning.

What maintenance or replacement will the Kastar NP-FT1 battery need over time?

As a lithium-ion cell, it requires no scheduled maintenance. Plan to replace the pack once run-time drops noticeably, typically after several hundred charge cycles.

What limit appears first during sustained shooting with this 1300mAh pack?

The 4.81 Wh capacity is the first limit; extended video or burst shooting will drain the charge before thermal protection activates.
