Critical lifesaving medical equipment, including automated external defibrillators (AEDs), rely on strong, charged batteries to ensure the best possible results. Proper, well-maintained batteries also protect the safety of both the patient and the user. Checking the battery status of devices and adhering to expiry dates is crucial to success, but mistakes are often made when selecting replacement batteries. Price is not the only factor—the manufacturer’s reputation and history with safety, reliability and performance should all be considered. Here are a few reasons to consult well-established and expert battery providers for help when selecting the correct replacement battery for your medical devices.
Experts understand the differences in battery resistance
The chemical makeup of a battery relies on specific electrochemical changes, such as electrolytes and ions. These interactions, along with electrode surface area, create a battery’s resistance. As a result, when you use your device, the voltage of the battery should decrease.
When the resistance of the replacement battery is incorrect, a quick but heavy draw on the battery can create a severe voltage drop. First, the unexpected drop can shut the machine down if the device has an internal battery malfunction cut-off. Secondly, the battery will quickly overheat, causing another significant concern for the patient and the user.
Experts can help you avoid overheating batteries
Batteries are designed for different scenarios, and what might work in one environment will not work in another. For example, it is normal for batteries to become warm when under load, but they should not become hot to the touch. When batteries overheat, such as when they are under extra stress due to improper resistance, several things can happen:
- You can experience a device override, causing the device to shut down. Some devices are programmed to prevent damage to internal components or danger to the patient/user if the battery overheats or experiences a sudden voltage drop.
- The battery connections can corrode, allowing the battery to leak and damage equipment or cause chemical burns.
- Batteries may fail completely without warning.
- Depending on the type of battery, they may spark, start a fire, or in extreme cases, explode.
Despite these concerns, selecting replacement batteries for your medical devices do not have to be difficult. Call us at NCE today and have an expert help you choose the right batteries for your equipment.
