You can try reactivating the battery. The following method is what I saw on the Internet. You might as well try it: Wrap the battery in newspaper then put it in a plastic bag for 3 days in the refrigerator and freezer (newspaper can absorb excess water). ); take it out at room temperature after 3 days. Leave it for 2 days; charge the battery after 2 days, then turn it on for a full test (it is estimated that 80-90% of the battery power can be recovered). )
This information was revealed by an engineer from a well-known battery manufacturer. Everyone has a refrigerator anyway.
If activation fails, this means that. the battery has been discarded and you need to purchase a new one.
How to activate the lithium battery of Olympus FE-5040 digital camera? What is the optimal time to charge each time?
~ If it is a battery manager~ Although there is no memory effect ~ but since the new phone has hardly been used after leaving the factory ~ the chemicals in the battery are in a sleep state ~ so it is used 2 to 3 times at first. It's best to run it with light and then rinse it for 12 hours to fully activate the chemicals inside. It can be used and recharged at any time in the future.
In principle, current lithium batteries have been activated before leaving the factory and do not require any further processing. If you are worried, you can use it completely the first two times until it turns off automatically, then recharge it once fully charged according to the instructions, you can continue charging it for 3 hours before use.
Use it normally after that and try to avoid charging it until it is fullfully discharged. Lithium batteries are generally rechargeable during use and have no memory.
