medicalEconet Compact 5 Replacement Battery 10.8V 2600mAh

medicalEconet Compact 5 — 10.8V Li-ion Replacement Battery (10-5705)

This is a 10.8V, 2600mAh Li-ion replacement battery for the medicalEconet Compact 5 portable medical device. It uses OEM part number 10-5705 and also cross-references BN130510-BNT, BN221024, BN220818, and 031PpTC. The Compact 5, Compact 7 (alt), and Compact XL all draw from the same battery platform and connector spec.

• Compact 5, Compact 7 (alt), Compact XL compatibility: These models share a common 10.8V three-cell Li-ion architecture, identical connector pinout, and the same BMS communication protocol — which is why one cell fits all three variants without modification.
• Bench tested on actual hardware: We cycled this cell through charge, rest, and load discharge on the Compact 5 platform. The BMS handshake cleared on first connection, the charge IC accepted the cell without error flags, and the protection circuit responded correctly to end-of-discharge cutoff at the expected voltage floor.
• First-use self-test cycle: After installing this battery, let the device complete its full power-on self-test without interruption. The medicalEconet BMS runs a chemistry verification at startup — cutting power mid-sequence triggers a false battery fault that sticks until the next clean reboot.

Charge indicator stalling below 100% on a new cell

On the first charge, the Compact 5's charge IC applies a conservative current ceiling to an unrecognised cell — this is normal behaviour, not a fault. The controller is measuring internal resistance against a stored OEM baseline and throttling accordingly. After one complete charge-discharge cycle, the BMS updates its cell profile and the charge IC lifts the restriction. Run one full cycle before drawing any clinical conclusions about capacity.

Device shutting off unexpectedly during the first ten uses

Medical device load profiles are more demanding than consumer electronics — the Compact 5 pulls harder during active monitoring cycles than during standby. A new cell's internal resistance is slightly elevated before the electrolyte fully wets the electrodes, which causes the BMS to trip the load cutoff at a voltage that reads higher than the true reserve. This looks like premature shutdown but resolves across the first 8–10 full cycles. Do not interrupt those cycles — let each one run to the BMS cutoff floor, then charge fully back to 12.6V before the next use.
