Due to the accelerating process of replacing lead-acid batteries with lithium-ion batteries, some people have switched to lithium-ion electric vehicles after buying lead-acid batteries. They can't help but wonder whether the previous lead-acid battery charger can be used for lithium-ion battery charging? Regarding this, relevant information shows that it is not feasible.

　　Due to the fact that lead-acid battery chargers are generally set to a two-stage or three-stage charging mode, the voltage levels of lithium batteries and lead-acid batteries do not match. There are also many types of lithium batteries, and the battery performance and battery protection board parameters may vary. Therefore, unlike lead-acid batteries, lithium batteries do not have universal battery chargers. Generally speaking, lithium batteries are shipped with a dedicated charger. To protect lithium batteries, a dedicated charger is required.

　　The following are the relevant precautions to pay attention to when charging lithium batteries:

　　1. To extend the lifespan of lithium batteries, it is necessary to regularly charge and discharge them. To develop the habit of charging an electric bike after using 80% of its battery, one should not wait for the battery to run out before charging. In addition, lithium batteries should not be stored for long periods of time.

　　2. When charging the electric vehicle battery, the switch lock must be closed and the battery cannot be inverted. When charging, it should be fully charged at once and should not be charged multiple times.

　　3. Electrical appliances should not be stored in a state of low power, so batteries need to be fully charged once a month when not in use.

　　4. When charging lithium batteries, it is necessary to use a matching charger. Due to the different raw materials and production processes of lithium batteries, the technical requirements for the charger are also different. Therefore, only using a dedicated charger for charging can prolong the lifespan of lithium batteries and prevent safety hazards.

　　5. When the lithium battery runs out of power, the power should be turned off for cycling, and the rebound voltage should not be used for driving to prevent serious power loss, in order to extend the battery's service life.

　　6. When charging the lithium battery of an electric vehicle, it is not advisable to immediately stop charging when the charging indicator light shows full charge for 1-2 hours.
