Frequently asked questions about batteries for medical devices

+ - What distinguishes medical batteries from standard batteries?
Medical batteries are specifically designed for use in medical devices. They must meet strict requirements in terms of safety, reliability and quality. Whilst conventional batteries are used in everyday devices, medical batteries are designed to function reliably even under heavy loads and to comply with the specific standards of the healthcare sector.
+ - What battery standards apply to medical devices?
Batteries and rechargeable batteries used in medical devices are subject to internationally recognised standards that ensure safety, quality and reliability. These standards guarantee that medical rechargeable batteries function reliably even under demanding conditions and that patient safety is ensured at all times. The declaration of conformity for our AKKUmed rechargeable batteries can be found on the relevant product pages.
+ - In which devices are medical batteries used?
Medical batteries are used in a wide range of devices, such as defibrillators, infusion and syringe pumps, patient monitors, ventilators and electrically adjustable hospital beds. In short: wherever a reliable power supply is essential in everyday medical practice.
+ - How long does a medical battery last?
The lifespan of a medical battery depends on the type of battery, how it is used and how it is maintained. High-quality lithium-ion batteries can last for several hundred to over a thousand charge cycles. Factors such as temperature, charging and discharging behaviour, and proper maintenance play a crucial role in this.
+ - How safe are rechargeable batteries in medical devices?
Medical batteries are equipped with safety mechanisms that prevent risks such as overheating, short circuits or deep discharge. They are tested to strict safety standards to ensure a reliable power supply in everyday medical practice. However, a high level of safety can only be guaranteed if tested and certified batteries are used.
+ - How do I choose the right battery for my device?
It is important that the voltage, capacity and design are precisely suited to the device in question. Furthermore, only batteries that meet the necessary standards and certifications should be used. Checking the manufacturer’s specifications and seeking expert advice will help you make the right choice and ensure the safety of the device.
+ - How should medical batteries be stored and maintained?
Medizinakkus sollten kühl, trocken und geschützt vor extremen Temperaturen aufbewahrt werden. Für die Lagerung empfiehlt sich ein mittlerer Ladezustand von etwa 40–60 %. Außerdem ist es wichtig, ausschließlich passende Ladegeräte zu verwenden und die Akkus regelmäßig auf ihre Kapazität zu überprüfen.
+ - How should medical batteries be disposed of properly?
Medical batteries must not be disposed of with household waste; instead, they must be recycled via special collection points or take-back schemes. Strict regulations apply to the transport and disposal of lithium-ion batteries in particular, in order to avoid environmental and safety risks.
+ - How can you tell if a battery is still in good condition?
There are various ways to check whether a battery is still working reliably. A first indication is its runtime in practical use: if the battery lasts significantly less time than usual, this suggests a reduced capacity. More accurate results can be obtained by measuring the capacity using a suitable charger or tester that displays the remaining battery capacity in milliampere-hours (mAh). The voltage can also be checked with a multimeter – if it is significantly below the target value, the battery is usually damaged. For medical devices, the following applies: batteries should be tested regularly in accordance with the manufacturer’s specifications, as safety and reliability are paramount here. If the readings are abnormal or there is any uncertainty, it is advisable to replace the battery to ensure the safe operation of the device.
+ - What is the 80-20 rule for lithium batteries?
The 80-20 rule describes a recommended method for charging and discharging lithium-ion batteries as gently as possible. It states that, ideally, the battery should not be charged to 100% or discharged to 0%. Instead, it is recommended to keep the charge level between approximately 20% and 80%. The reason: Extreme charge states place greater strain on the cell chemistry and shorten the service life. By adhering to the 80-20 rule, more charge cycles can be achieved, capacity can be maintained at a stable level for longer, and the service life and reliability of the battery can thus be significantly extended. Particularly in medical technology, where batteries play a central role in operational safety, this method contributes to greater reliability.

Frequently asked questions about batteries for two-way radios

+ - How long does a radio battery last in use?
The battery life depends on several factors: the type of battery (e.g. Li-ion, NiMH), the capacity (in mAh or Wh), the radio’s power consumption (transmission time vs. standby) and environmental conditions such as temperature. In user manuals for radio devices, you will often find specifications such as ‘up to 16 hours in active everyday use’ or ‘several days in standby mode’.
+ - Can I mix and match radio batteries from different manufacturers?
This is problematic. Even if the voltage and connector match, internal parameters (cell chemistry, BMS, protection circuits) may differ. A battery without the correct protection circuitry can interfere with the charging electronics or cause damage. It is always better to use compatible batteries or those recommended by the manufacturer.
+ - How can I tell when a battery needs replacing?
A radio battery should be replaced if it shows certain signs of wear and tear. Typical signs include a significantly shorter runtime than usual, or the device reporting a low battery very quickly despite being fully charged. If the battery becomes unusually hot whilst charging, or if the charge indicator flickers or is unreliable, this is also a sign of deteriorating quality. In some cases, the radio cannot be switched on at all, even though the battery is charged – this too indicates that a replacement is necessary.
+ - How should I charge radio batteries?
Radio batteries should always be charged using a charger that is precisely matched to the voltage, current and battery type. Continuous charging should be avoided; it is therefore advisable to remove the battery from the charging cradle once it is fully charged. Ambient temperature also plays an important role: ideally, charging should take place at moderate temperatures and not in extreme cold or heat. To extend the battery’s service life, it is advisable to keep charging cycles moderate and not to fully charge the battery to 100% at every opportunity. Many two-way radios also feature charge indicators, LED signals or warning tones that indicate when the battery should be recharged – these indicators should be heeded at all times.
+ - Can a charger be too powerful for the battery?
Yes, if the charging current (or power) exceeds what the battery or the charging electronics can handle, this can lead to overheating or cell damage. That is why a precisely matched or intelligently controlled charger is particularly important.
+ - What is deep discharge and how can I prevent it?
Deep discharge means that a battery is discharged below a critical voltage, which can cause permanent damage to the cell. Many two-way radios and battery management systems issue a warning via an LED indicator or an audible alert when the battery level becomes critically low. Pay attention to such warning signals and recharge the battery in good time to prevent deep discharge.
+ - Should you calibrate radio batteries?
Regular calibration is not necessary for modern lithium-ion batteries. However, it may be advisable if the radio’s charge indicator displays inaccurate readings or the device switches off prematurely. In this case, a controlled calibration can help: the battery is discharged almost completely and then fully recharged. It is important to avoid deep discharge – in other words, to charge the battery in good time before the voltage drops into a critical range. Such calibration should only be carried out occasionally and does not replace regular maintenance or the timely replacement of worn-out batteries.
+ - Welche Akkutypen sind bei Funkgeräten üblich?
Gängige Typen sind Lithium-Ionen (Li-Ion), Lithium-Polymer und NiMH. In einigen Spezialfällen werden auch LiFePO₄-Akkus eingesetzt – sie zeichnen sich durch hohe Zyklenfestigkeit und Sicherheit aus.
+ - How do I check the capacity of my radio battery?
Verwenden Sie ein geeignetes Messgerät oder Ladegerät mit Kapazitätsmessung (z. B. mAh-Zählung). Testen Sie alternativ praktisch: Laden Sie den Akku voll, benutzen Sie das Funkgerät unter standardisierten Bedingungen und schauen Sie, wie lange es bis zur Entladung läuft. Abweichungen gegenüber dem Neuzustand geben Hinweise auf Verschleiß.
