3 x 3 facts about Jauch button cells for extreme temperature requirements from -40°C up to 125°C The “High Temperature” button cells CR2032HT, CR2050HT and CR2450HT are ideally suited for use under extreme temperature requirements, for example for electronic toll collection systems (ETC) or the metering sector. The button cells also meet the high-temperature requirements […]
When developing battery packs, the question arises as to which safety system the pack should be equipped with. Is a Protection Circuit Module (PCM) sufficient? Or should a Battery Management System (BMS) be integrated? What are the differences between the mechanisms? And what advantages and functions does which protection mechanism offer? The answer here, as […]
In the consumer sector, the decision for the right battery is made quickly. There are standard batteries which fit in consumer applications. However, in the industrial or medical technology sector, the situation is different. For these applications, “off-the-shelf” batteries are often not suitable. There are special requirements concerning safety or space. The solution: individually developed […]
Charging Process: Lithium-batteries are charged with constant current until a voltage of 4.2 V is reached at the cells. Next, the voltage is kept constant, and charging continues for a certain time. The charger then switches off further charging either after a preset time or when a minimum current is reached. In the rare event […]
What special features are there to consider when designing-in a lithium polymer cell? An important point, is certainly the so-called “swelling”, the natural swelling of a lithium polymer cell in a fully charged state and over cycles. A fully charged cell is thicker than a discharged one. During charging, the electrodes become thicker, so the […]

Passivation of Lithium Thionyl Chloride Batteries Lithium thionyl chloride (LiSOCl2) batteries are special in many ways; with 3.6 volts, they have the highest cell voltage of any primary batteries available. They are also extremely durable and can be safely stored for long periods of time. This excellent shelf life is the result of another special feature of […]
Amendment to UN 38.3: Test Report for Lithium Batteries Becomes Mandatory January 1st, 2020 was an important date for anyone shipping lithium cells or batteries. From that date forward, all shippers must be able to provide a test summary proving the products shipping have passed the UN 38.3 test for the transport of lithium batteries. […]
The Right Battery for Locking Cylinders and Locking Systems Electronic locking cylinders have long since replaced mechanical locks in many companies. Not the key, but the transponder or key card is granting access to the company building. In private homes, too, the trend is moving towards the electronic lock. Depending on the product and manufacturer, […]
