NetScout OneTouch AT 7.4V 6800mAh Compatible Battery

NetScout OneTouch AT Network Assistant — 7.4V Li-ion Replacement Battery

This 7.4V 6800mAh Li-ion battery fits the NetScout OneTouch AT Network Assistant, a handheld network tester used for cable qualification, diagnostics, and signal analysis in the field. It replaces the original pack and restores full operating capacity to the platform. Capacity figures are taken directly from the cell specification — 50.32Wh total energy.

• OneTouch AT platform compatibility: The OneTouch AT and OneTouch AT Network Assistant share the same battery bay dimensions (72.84 × 60.14 × 42.80mm), voltage rail, and connector pinout. The BMS handshake on both units reads the same cell chemistry registers, so this pack is recognised without firmware prompts or error flags.
• Bench tested on actual hardware: We ran this pack through the OneTouch AT's probe initialisation and active link-test cycles. The BMS held stable through the current spike at probe module power-up — no cutoff triggered. Cell voltage stayed within the operating window across sustained diagnostic logging sessions.
• Pre-deployment calibration on the OneTouch AT: After fitting this pack, run a full calibration cycle from the OneTouch AT instrument menu before field deployment. The unit maps battery state during calibration, and skipping this step causes premature low-battery warnings during the first active measurement session — even with a fully charged pack.

BMS cutoff during probe module initialisation on the OneTouch AT

When the OneTouch AT powers up a connected probe or link module, there is a brief inrush current that exceeds normal steady-state draw. An aged or partially discharged original pack may sag below the BMS undervoltage threshold during that spike, triggering an immediate cutoff. This replacement pack uses higher-capacity cells with lower internal resistance, which reduces voltage sag during the initialisation surge. If cutoffs were occurring consistently at probe power-up, fitting this pack and running one full charge cycle should resolve the issue.

OneTouch AT not recognising a new pack after months of storage

Li-ion cells self-discharge during storage, and if the pack voltage drops below approximately 6.0V, the BMS enters a protection state and blocks normal charge acceptance. The OneTouch AT charger may show no charging activity or a fault indicator. To recover the pack, connect it to the OEM charger and leave it for 20–30 minutes — most BMS circuits include a trickle pre-charge mode that brings the cells back above the recovery threshold before switching to full charge current. If the charger shows no response at all after 30 minutes, check that the charger output is live using a multimeter at the connector — target above 8.0V DC.
