Rohde & Schwarz EB200 Compatible Battery 11.1V 7800mAh

Rohde & Schwarz EB200 — 11.1V Li-ion Replacement Battery

This 11.1V 7800mAh (86.58Wh) Li-ion pack replaces the internal battery in the Rohde & Schwarz EB200 portable RF monitoring receiver. The EB200 is a field measurement instrument used for EMF surveys, radio frequency exposure assessments, and regulatory compliance monitoring. This replacement restores operating power for technicians conducting on-site measurement sessions where mains power is unavailable.

• EB200 platform fit: The EB200 draws sustained current through its RF front-end and signal processing chain simultaneously. This pack matches the 11.1V nominal rail and physical form factor the instrument expects. The BMS communicates charge state to the EB200's power management circuit to support the instrument's built-in battery indicator.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles, monitoring BMS response under the combined load of the receiver front-end and display backlight. The BMS held voltage within the EB200's operating window across the full discharge curve without tripping a cutoff.
• First-deployment calibration: After fitting this pack, run a full calibration cycle through the EB200's instrument menu before heading into the field. The EB200 maps battery state during calibration — skipping this step causes premature low-battery warnings during your first measurement session, even with a fully charged pack.

BMS cutoff when the EB200 initialises its RF probe or antenna input

When the EB200 powers up its RF front-end and probe interface simultaneously, there is a brief current spike as the input circuitry charges internal coupling capacitors. On a battery with a tightly calibrated BMS, this spike can read as an overcurrent event and trip the protection circuit before the instrument finishes booting. This pack's BMS is set with headroom for that initialisation draw. If shutdown still occurs at power-on, check that the battery is charged above 11.5V before attempting another boot cycle.

EB200 readings resetting or dropping to zero mid-logging session

This is a voltage dropout symptom, not a software fault. During extended logging sessions, sustained current draw across the RF chain and data-logging subsystem causes cell voltage to sag momentarily below the EB200's minimum operating threshold. The instrument resets the active measurement session to protect data integrity. A cell delivering full capacity at rest may still sag under the combined load if the cells have degraded through deep discharge cycles. Replace the pack if resting voltage reads above 11.1V but the instrument resets under load — confirm resting voltage with a multimeter across the battery terminals before field deployment.
