Product Description
L18650-3HSM Replacement Battery for Hospira SedLine EEG Monitor
The L18650-3HSM is an 11.1V 3350mAh Lithium-Ion intelligent battery pack assembled in the USA for use in the Hospira SedLine brain function (EEG) monitor. It is a direct replacement for OEM part number 5139-0004 Rev A and ships fully charged and tested — ready for immediate clinical deployment without an initial charge cycle or bench validation.
Application: Hospira SedLine Brain Function Monitor
The SedLine monitor is a processed EEG device used to measure depth of anesthesia and sedation during surgery and in the ICU. Originally developed by Masimo and distributed under the Hospira brand — now marketed under ICU Medical following Hospira's acquisition — the SedLine requires a reliable, communicating battery pack to maintain uninterrupted neuromonitoring through extended surgical and critical care sessions. The L18650-3HSM installs directly via the original 6-position connector interface without modification.
Quality and Safety
The L18650-3HSM is built by Energy+ to the highest quality standards, incorporating safety protection circuitry and premium 18650 Li-Ion cells in a black heat shrink pack construction. Each unit undergoes full functional testing and is shipped at full charge, confirming cell health and smart circuit communication before leaving the facility.
Frequently Asked Questions
What monitor is the L18650-3HSM compatible with?
The L18650-3HSM is designed for the Hospira SedLine brain function (EEG) monitor, also known under the ICU Medical brand following Hospira's acquisition. It replaces OEM part number 5139-0004 Rev A. Confirm your monitor model and OEM battery part number against your equipment documentation before ordering.
What OEM part number does this replace?
The L18650-3HSM replaces 5139-0004 Rev A — the Hospira/ICU Medical OEM battery for the SedLine monitor.
Does this battery ship charged and ready to use?
Yes. The L18650-3HSM ships fully charged and tested. No initial charge cycle is required before installation, and no bench validation is needed — it is ready for immediate clinical deployment upon arrival.
Is this an OEM Hospira or ICU Medical battery?
No. The L18650-3HSM is an aftermarket replacement battery manufactured by Energy+ in the USA. It is designed to meet the specifications of the original OEM battery and is not an official Hospira or ICU Medical product.
What is the warranty?
The L18650-3HSM carries a 12-month warranty.
Why does the part number reference 18650?
18650 refers to the cylindrical Li-Ion cell format used inside this battery pack — 18mm diameter × 65mm tall — the same cell format used in many high-performance battery applications. The L18650-3HSM uses three of these cells in series to achieve 11.1V nominal voltage.
