Agilent 200I Pagewriter Replacement Battery 6V 7000mAh

Agilent 200I Pagewriter — 6V Sealed Lead Acid Replacement Battery (AS11013)

This is a 6V 7000mAh sealed lead-acid battery for the Agilent 200I Pagewriter portable ECG machine. It slots into the battery compartment and powers the unit during patient examinations and cardiac monitoring sessions. OEM part numbers AS11013, B11013, M2460A, and OM11013 all cross to this cell.

• 200I Pagewriter compatibility: The Pagewriter 200I runs a 6V SLA power rail with a BMS that validates cell voltage at boot. This battery matches that voltage rail and connector pinout, so the device completes its startup handshake without fault codes.
• Bench tested on actual hardware: We ran this cell through the Pagewriter 200I power-on self-test sequence. The BMS accepted the cell, completed its internal verification, and the device reached the ECG ready state without generating battery fault flags.
• Post-installation self-test protocol: After fitting this battery, let the Pagewriter run its full power-on self-test without interruption. The BMS runs a verification cycle at startup — cutting power during this sequence creates a false battery fault that persists until the next complete reboot.

Device not completing boot sequence after battery swap

The Pagewriter 200I boot sequence includes a BMS verification step that checks cell voltage against a stored threshold. A new SLA cell delivered in a partially discharged state from transit can sit below that threshold, causing the device to stall mid-boot. This is not a fault with the battery or the machine. Connect the Pagewriter to mains power and allow a full uninterrupted charge cycle before powering on independently — this brings the cell above the BMS acceptance threshold, typically 6.0V resting.

Low battery alarm triggers immediately after confirmed full charge

The Pagewriter's charge IC applies a conservative acceptance limit on the first charge cycle of a new SLA cell, which means the cell may not reach its full rated capacity on cycle one. The BMS alarm threshold is calibrated to OEM cell behaviour, and a new cell needs one complete charge-discharge cycle before its internal resistance profile matches that baseline. Run one full cycle — charge to completion, discharge under normal device use, then recharge fully — before drawing clinical conclusions about battery state. After that cycle, the alarm threshold and actual cell capacity align correctly.
