Batteries for medical technologies

Rechargeable batteries for medical laboratory accessories are often nickel-metal hydride rechargeable batteries. These are particularly suitable for use in medical technology as they have a low self-discharge rate. They can therefore ensure that smaller devices with low energy consumption in particular can remain in use for a long time without the battery having to be replaced or recharged. Another type of battery that is often used in medical devices is the tried and tested lithium-ion battery.

With both battery types, care must be taken to avoid extreme discharging and overcharging. This incorrect charging damages the battery and can lead to a significantly shorter service life. It is therefore essential to optimise the charging process. Ideally, the batteries should have a permanent charge level of 30-70%. This will ensure that you can enjoy your medical technology battery for a long time. The charging process should ideally take place at a temperature between 5 and 45°C.

If the battery is not used for a longer period of time and is therefore stored, there are also a few things to consider here. Lithium-ion batteries should ideally be stored at 5°C–10°C. It is also important that the battery is never stored at a temperature below 0°C. The charge level should be around 40-50%. If the battery is permanently installed in a device, this should be switched off.

If the rechargeable battery and therefore the medical device is in operation, the ambient temperature should ideally be between -10°C and +55°C. At higher temperatures, there is a risk of the battery catching fire.

Finally, it should be mentioned that rechargeable batteries should generally be charged, stored and replaced in accordance with the manufacturer's instructions. This is the only way to effectively prevent battery failure.
