High-capacity Li-ion replacement

This 7800 mAh lithium-ion battery delivers 10.8 V and 84.24 Wh for Anritsu MS2024, MS2026 and MS203x series instruments. It also fits JDSU MTS-6000 OTDR and PHASCAN ultrasonic phased-array flaw detectors. The pack is a direct replacement for part numbers LI204SX, 1420-0868 and A6188-67004. No modifications are required for installation.

Stable output and safe chemistry

Lithium-ion cells maintain steady voltage during extended field measurements. The 10.8 V nominal rating matches the original equipment specification exactly. Built-in protection circuits guard against overcharge, deep discharge and short circuits. The black casing meets the same thermal limits as the factory pack.

Plug-and-play fit for daily use

The battery slides into the standard compartment on supported Anritsu, JDSU and PHASCAN units without adapters. It replaces variants marked 7.8 A, 60, 66 and 6000 series part codes. One unit is included in the package. Technicians can swap packs on site to keep test equipment running through long shifts.

Questions about this item

How do I install the LI204SX battery in my Anritsu MS2024, and what step do people often miss?

Power off the device, remove the old pack, align the LI204SX connector, press firmly until it clicks, then charge fully before first use; the step often missed is the initial full charge.

What maintenance or replacement will the LI204SX need over time?

The 7800mAh Li-ion cells gradually lose capacity; plan to replace the pack when run-time drops below your field-test requirements, typically after several hundred charge cycles.

What limit appears first during sustained use of the LI204SX in an MS2026?

The 10.8V output remains stable until the 7800mAh capacity is depleted; the practical limit is total run-time per charge rather than voltage sag or thermal throttle.
