Ambient temperature, whether too high or low, among the risk factors that have a big impact on life and the life of batteries and accumulators electronic devices. If the batteries are subjected to a longer period of very low temperatures, risk of permanent damage.
Battery life have a negative impact not only winter frosts and summer heat. Although the battery is best stored in a cool environment, the temperature under 15 degrees already causes loss of capacity. But on the other hand, the storage temperature should not too long exceed 20 degrees. Modern battery is also appropriate to recharge more often - though they still left plenty of capacity.
Effect of long exposure to low temperatures battery life of mobile devices can try every skier or anyone who moves to a longer period in the freezing cold outside. Smartphones, tablets or even cameras in freezing temperatures much faster discharge. To keep the phone on income for emergencies or to be able to shoot continuously throughout the day, so please bring your charged PowerBank or spare battery into the camera. But there is one trick: wear electronic devices as close to the body and keep it so warm. The batteries in the backpack can be at least partially protected from frost simple Thermocover.
Also important is the correct handling of batteries after coming into heat when the batteries are not only cold, but also dewy. "Very bad idea is defrosted 'battery after coming from outside in the heat or perhaps by the fireplace. Exposing the battery to temperatures above 60 degrees is liable to end their explosion and subsequent fire, "explains Radim Tlapak (BatteryShop.cz). Before charging the battery should be allowed to slowly warm to ambient temperature and wiped dry.
Low temperatures cause a decrease in battery capacity, which is then necessary at shorter intervals to change or recharge. Prolonged exposure to freezing temperatures it may cause permanent damage to the battery. The danger for the battery, however, are not only low temperature, but also water and humidity, due to which corroded contacts and other delicate components. Wet batteries should be performed prior to loading on the dried thoroughly, but no hair dryer or other source of direct heat.
For devices that do not plan for a long time, we should remove the battery and store management. Now unsuitable method of storage may damage the battery and reduce their usable capacity. "The ideal environment for the storage battery is a dry place with a constant temperature of around 15 degrees. Batteries should be stored charged, because even if you no longer lose their capacity is required once in a while to recharge, "says Radim Tlapak.
Poor storage and complete discharge can damage mainly lithium-ion (Li-Ion) and lithium polymer (Li-Poly) batteries, which today can be found in virtually all mobile phones, tablets, laptops and cameras. These types of batteries do not suffer from a so-called memory effect, so it does not matter when you are recharged in only partially discharged state. Conversely damaged if they are completely discharged. Therefore, the lithium battery equipped with a safety fuse, which is running out of power disconnects. Lithium based batteries per month lost about 3 percent of its capacity, while the older nickel-metal hydride battery (NiMH) spontaneously lose up to a third of capacity per month.
