1. Gently wipe the metal contacts on the lithium ion battery and the metal contact on the metal contact on the mobile phone, which helps charging status and electricity. 2, will use the old mobile phone lithium-ion battery with automatic shutdown to cover it firmly, and we will try to pay three layers in the package, so that the battery is in a vacuum state.
Then, the three-layer newspaper is added outside the plastic wrap, so that the lithium ion battery is completely sealed. The refrigerator is placed in the refrigerator, after 48 hours, the battery is removed, and the lithium-ion battery does not cause surface expansion or deformation due to freezing. After a while, then charge.
3, let the lithium battery close to the scrapped completely discharge, then recharge the activation battery. The detailed way is to discharge the mobile phone, which is to reach a deeper and reproduction by depleting internal energy, which takes some unconventional approaches. How to keep a lithium-ion battery correctly? 1 Due to the self-discharge phenomenon of lithium ion batteries, if the battery is not used, the battery voltage cannot be lower than its cutoff voltage, preferably from 3.
8 to 4.0V; 2 proposal to charge the lithium-ion battery for half a year, Is the battery over the cutoff voltage; 3 battery storage ambient temperature and humidity should be appropriate, to operate according to specifications; Packet charging. .
