Direct Replacement for JD725 and JD726
This 11.1 V lithium pack replaces the original battery in VIAVI JDSU JD725 and JD726 test instruments. It supplies 7500 mAh capacity and 86.58 Wh energy rating for field measurements. The unit weighs 615.0 g and measures 213.11 x 58.51 x 22.22 mm.
Fits Existing Chassis Without Modification
The pack uses the same form factor and connector layout as the factory cell, so it slides into the instrument’s battery bay with no adapter required. Built-in overcharge, over-discharge, over-voltage and short-circuit protection safeguards the host device during operation. ISO 9001, RoHS, CE, UN 38.3 and MSDS certifications confirm compliance for transport and workplace safety.
Steady Output During Extended Test Sessions
Protection circuitry maintains stable voltage across the full discharge curve rather than allowing a rapid drop-off near empty. This behaviour supports long cable-certification runs and continuous OTDR measurements without unexpected shutdown. The lithium chemistry also reduces self-discharge when the instrument is stored between jobs.

Questions about this item
How long will the 7500mAh capacity last during continuous field testing?
The 7500mAh lithium pack delivers 86.58Wh at 11.1V, so runtime depends entirely on the instrument's current draw; higher loads drain it faster.
Does the pack run hot or make noise during all-day operation?
Lithium cells generate no acoustic noise; heat rises only under heavy discharge, and the built-in protection circuit limits over-current to keep temperatures controlled.
Which VIAVI instruments accept this replacement without modification?
It fits the JDSU JD726C and JD725C models exactly, matching the original 213.11 x 58.51 x 22.22mm form factor and 615.0g weight.
