Summer is now slowly getting underway in Germany and we are all looking forward to the high temperatures. But have you ever thought about what this means for your battery-powered device? The heat has a significant impact on the performance and lifespan of batteries<\/a> in portable devices such as smartphones, laptops and cameras. In this article, we answer two important questions:<\/p>\n\n\n\n

How does the summer heat affect the performance of batteries in portable devices?<\/strong><\/p>\n\n\n\n

Heat is fundamentally bad for battery cells. The general scientific rule is that chemical reactions double with a 10\u00b0C increase in temperature. This means that your devices age much faster at high temperatures. Black smartphones and tablets in particular can get very hot in direct sunlight, for example behind a window. Modern lithium-ion batteries are specified up to a temperature of 60\u00b0C, but this limit can easily be exceeded in extreme heat. Short-term overheating does not usually pose a safety risk. However, this should be avoided as it significantly accelerates the ageing process of the battery.<\/p>\n\n\n\n

The heat increases the pressure in the battery cells, which in the worst case can lead to complete failure. In addition, the devices monitor the battery temperature and first reduce the display brightness before switching themselves off in extreme cases. Even stricter temperature limits apply when charging: Rechargeable lithium batteries may only be charged up to 45\u00b0C, otherwise the charger switches off for safety reasons.<\/p>\n\n\n\n

Are there ways to actively cool my battery at high temperatures?<\/strong><\/p>\n\n\n\n

Actively cooling your appliances is not a good idea, as this can lead to damage due to condensation. However, there are some simple measures you can take to protect your appliances from overheating:<\/p>\n\n\n\n
