Compatible OTDR Power Source

The KingSener BDR15D is a replacement lithium-ion battery built for Yokogawa AQ7275 and AQ7270 optical time-domain reflectometers. It restores portable operation for field technicians who rely on these specific instruments for fibre verification and troubleshooting tasks.

Capacity and Runtime Limits

Rated at 2100mAh and 22.68Wh, the pack delivers 10.8V to the instrument during extended measurement sessions. Runtime scales with the OTDR’s active test cycle and display brightness; continuous high-power averaging will deplete the charge faster than intermittent single-trace captures.

Voltage Match Requirement

The 10.8V output must match the original specification of the AQ7275 or AQ7270; a different voltage will prevent the device from powering on or cause immediate shutdown. Verify the original battery label before ordering to confirm this exact voltage is required.

Questions about this item

Will this 10.8 V 2100 mAh pack fit my existing Yokogawa AQ7270 OTDR without modification?

Yes, the BDR15D is listed as a direct replacement for both the AQ7270 and AQ7275 models.

How can I verify the new battery is delivering the rated 22.68 Wh after installation?

The OTDR's on-screen battery meter should show full capacity and provide run-time consistent with the 2100 mAh rating.

Does the package include only the battery or are cables and a charger also supplied?

Only the replacement battery cell is included; the original charger and any connecting leads are reused.
