WHY A RELIABLE BATTERY IS CRITICAL FOR FUSION SPLICING
Uninterrupted Workflow: Provides sufficient power to complete splicing projects, ribbon splicing, or long OTDR trace analysis without stopping to charge.
Stable Splicing Arc: A stable voltage supply is crucial for the splicer's electric arc system to create consistent, low-loss fusion splices.
Field Productivity: Essential for technicians working at remote cell towers, data centers, or along fiber routes where AC power is unavailable.
Protects Equipment Value: A simple battery refresh is the most economical maintenance to preserve the functionality and resale value of your high-precision splicer.
SAFETY, CHARGING & FIELD OPERATION NOTES
For Professional Technicians: Intended for use by certified fiber optic splicers, network installers, and field engineers.
Use Sumitomo Approved Charger Only: Must be charged using the official Sumitomo T-400S charger or docking station. The splicer's intelligent charging system is calibrated for this specific battery. Using an incorrect charger is unsafe.
Follow Manufacturer Guidelines: Adhere to all battery handling, storage temperature, and operational instructions in your Sumitomo T-400S User Manual.
Transport & Disposal: The 35.64W h capacity is well within standard limits for air travel with carry-on luggage (always verify current airline rules). Recycle at a certified e-waste facility.
