Cameron Sino BU-25 Replacement Battery

This 2600 mAh lithium-ion pack replaces the original Sumitomo BU-25 cell for Fusion Splicers BU25, Type-25 and Type-25e equipment. It delivers 11.1 V and 28.86 Wh to power survey and test instruments in the field. The fully decoded chip communicates with the splicer exactly like the factory battery.

Simple Field Installation

The pack slides into the splicer battery compartment and locks with the original latch. Align the connector carefully before pressing it home; a loose pin will prevent the device from recognising the new cell. No tools are required, and many technicians follow online video guides to complete the swap in minutes.

Capacity and Runtime Limits

At 2600 mAh the battery supports extended splicing sessions, typically lasting through a full day of fibre termination work. Runtime drops noticeably in cold environments or when the splicer heater runs continuously. After two or three full charge cycles the pack reaches its rated capacity.

Questions about this item

How do I confirm the battery is working correctly after installing it in my Sumitomo fusion splicer?

After installation the splicer should power on and display the expected voltage of 11.1 V. A new pack reaches full performance after two or three complete charge and discharge cycles.

What comes in the box and do I need to buy a charger separately?

The package contains one 2600 mAh lithium-ion battery measuring 81.00 x 60.00 x 20.30 mm and weighing 154.2 g. No charger is included; use the original Sumitomo charger for the BU-25, Type-25 or Type-25e.

Which capacity should I choose for the BU-25, Type-25 or Type-25e splicer?

This replacement is rated at 2600 mAh and 28.86 Wh, matching the original Sumitomo BU-25 specification for all three splicer models.
