Studi Pemanfaatan Baterai Lithium 18650 Bekas Sebagai Penyimpan Energi Listrik Untuk Penerangan

In the modern era, electronic devices around the world have used batteries as a stored power source so that the devices are flexible and can be carried everywhere without having to be constantly connected to an electrical power source. However, the battery has a service life depending on the time and method of use of the battery, and if the battery on the device has been damaged , it must replaced with a new battery. Based on the results of field observations, the most common type of used electronic device battery found is lithium batteries in 18650 so that with the increasing use of batteries in electronic devices, many used battery e-wastes, especially 18650 lithium batteries, are found to be unused. The ability to store electrical energy used 18650 lithium battery after sorting properly and made into a 12 volt pack battery can store power of 77.83 Ah. produces excellent performance that can be used for power backup during power outages, for lighting residential houses, for lighting gardened huts, for lighting fishing boats when in the middle of the sea and other DC load uses.
