Practical tip: The right way to care for rechargeable and non-rechargeable batteries

Modern fire companies use a variety of devices that are powered by rechargeable or non-rechargeable batteries. This ranges from simple radio devices and portable lighting bodies right through to thermal imaging cameras. The various devices are often powered with different types of rechargeable and non-rechargeable batteries. Battery types include nickel cadmium, nickel metal hydride, lead gel rechargeables, or lithium-ion rechargeables. Some of these technical devices are used very irregularly or rarely. This is not ideal for the battery's service life.


Batteries for the various devices should always be "maintained" and handled according to the manufacturer's instructions in the owner's manuals. However, considering the wide variety and large number of technical devices in a firefighting vehicle that use batteries, this represents an organizational challenge that is almost impossible to manage.


Therefore, regularly discharging and charging the batteries is recommended in order to maintain performance.


To make this as straightforward as possible for the fire department, Rosenbauer recommends using all rechargeable battery-powered devices once per month and to completely discharge the batteries by leaving the device on until it switches off automatically. The batteries or devices should then be fully re-charged. This measure is not necessary for some rechargeable batteries of the latest generation, but following this procedure will not harm the battery or device either. This tip is useful not only for the fire department, but also for everyday life!
