Current Interrupt Device (CID) | Cuts off circuit permanently when triggered by excessive pressure, temperature, or voltage. |
Vent | Releases gas during anomalies and can be resealed. |
Tip: Always verify that your lithium battery pack includes over-charge, over-discharge, over-current, and cell balancing protection. These features help prevent thermal runaway and extend battery life.
You must also consider risks such as fires, leaks, fumes, and blasts. Fires result from thermal runaway, leaks release toxic chemicals, fumes pose evacuation risks, and blasts can impact patients with implantable devices. Battery alarming systems provide early warnings for abnormal conditions, enhancing safety in monitoring applications.
2.2 Capacity and Runtime (Ah)
Battery capacity determines how long your monitoring device operates between charges. You must match battery capacity to the device’s runtime requirements to avoid interruptions in patient care. Capacity, measured in ampere-hours (Ah), reflects the total charge the battery can deliver.
Calculate the average power consumption of your monitoring terminal.
Estimate the required runtime for continuous operation.
Select a lithium battery with sufficient capacity to meet these needs.
You should also consider battery alarming features that notify you when capacity drops below safe levels. This proactive approach helps you schedule maintenance and replacement before performance declines.
Parameter | Importance |
|---|---|
Battery Capacity | Ensures uninterrupted monitoring |
Runtime (Ah) | Matches device operational requirements |
Alarming System | Alerts for low capacity and maintenance |
Note: Always verify the manufacturer’s specifications for battery capacity and runtime. Overestimating capacity can lead to oversized batteries, while underestimating can cause device shutdowns.
2.3 Device Compatibility
You must ensure that your lithium battery matches the voltage, connectors, and recharge requirements of your monitoring terminal. Incompatible batteries can cause operational failures and reduce device performance.
When selecting lithium batteries for home care monitoring terminals, check the following:
