Replacement AVACOM battery for mobile phones from high quality componentsAVACOM batteries for mobile phones contain only high quality cells that show high performance and long service life. The capacity shown on the battery matches the actual battery capacity. The capacity is tested several times, both during the production phase and after loading and during the sales cycle.Batteries are equipped with gold-plated connectors and the latest control electronics for trouble-free communication with the device. At the same time, they contain a number of safety features that prevent overcharging, low-voltage, over-current charging and short-circuit. AVACOM batteries are a good replacement for your original battery. How to keep the battery in good conditionThe battery is partially charged at the factory, yet its capacity and performance are below 100%. Therefore, for optimal battery formatting, it is recommended to repeat the charge and discharge cycle at least 3 times at the beginning. Battery capacity reduces the permanent connection to the power supply, so we recommend that you disconnect the device from time to time. If the battery is not in use, store it in a dry place and check it for approximately six months. What does the battery damage?One of the most common causes of battery degradation is when you drop it down completely and do not use it for a long time. Do not expose the battery to temperatures above 60 ° C. If the battery is exposed to temperatures below 5 ° C, charge it only at room temperature. Only use the battery in the devices for which it is intended. Also be careful that the battery is not subject to a short circuit or higher discharge currents. Protect it from mechanical damage, chemical agents and moisture.
