About this replacement
Aitecs 2016 Syringe Pump — 7.2V Ni-MH Replacement Battery (110652-O)
This is a 7.2V, 2700mAh Ni-MH replacement battery for the Aitecs 2016 Syringe Pump. It replaces OEM part number 110652-O and fits this specific infusion device used in clinical and portable healthcare settings. Capacity is rated at 2700mAh (19.44Wh), matching the original specification.
- Aitecs 2016 Syringe Pump fit: The 2016 platform uses a 7.2V Ni-MH cell pack with a BMS handshake tuned to this chemistry. Swapping to a different voltage or chemistry causes the pump to reject the battery outright at self-test, which is why this replacement stays with Ni-MH rather than Li-ion.
- Bench tested on actual hardware: We cycled this cell through the Aitecs 2016 boot sequence and monitored BMS response under the pump's load profile. The BMS passed the self-test without faults after the first full conditioning cycle.
- Post-installation self-test protocol: After fitting this battery, let the Aitecs 2016 complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup — cutting power during this sequence logs a persistent battery fault that will not clear until the next complete reboot cycle.
Why the Aitecs 2016 flags a battery fault on a brand-new cell
The 2016's charge IC applies a conservative acceptance threshold on first contact with a new Ni-MH cell. A freshly manufactured cell has not yet established full electrochemical capacity, so the BMS can read it as marginal rather than new. This is not a fault with the battery — it is the pump's self-protection logic working as intended. One full charge-discharge cycle recalibrates the threshold and clears the flag permanently.
Charge indicator stops short of 100% on the first charge
The Aitecs 2016 uses a delta-V termination algorithm to detect full charge in Ni-MH cells. On a new cell, the voltage curve is flatter than a broken-in cell, so the algorithm terminates early and the indicator stalls below 100%. This is not a capacity defect. Run the battery down under normal pump operation, then charge fully — the delta-V signature normalises after one complete cycle and the indicator reaches full charge correctly from that point forward.
