New lithium battery first charge method: Lithium-ion batteries must be charged for 10-12 hours, lithium-ion batteries have almost no memory, and nickel-metal hydride battery charging is fundamentally different, but there is an activation problem, if the battery is placed for a long time, then it needs to be activated, the battery has been activated at the factory, if it needs to be activated for a long time, it needs to be activated by itself. The method is to use up the charge for more than 8 hours, and then cycle three times, lithium-ion battery is the best battery at present, light and almost no memory, if it has been activated there is no need to charge more than 10 hours, although the battery has a protective line, But it is best not to charge too long, I bought two years ago ion battery cell phone does not care, whenever you want to charge, until now the battery capacity is still very good.
Charge the battery directly with a constant current and constant voltage source. Without taking apart the battery. Try to make a small slit in the label. When torn, it should be an aluminum shell wrapper. Use the black watch pen of constant current source against the negative input end of the protection plate.

The red watch pen charges against the aluminum case. The voltage can be stopped above 3V. At this time, the protective effect of the lithium battery protection board is cancelled naturally. Wrap the exposed aluminum casing with tape. You can then charge the battery directly with the charger. Need to pay attention to whether the battery has a drum. If there is, this battery will not work.
