How to distinguish between lithium-ion battery charger and lead-acid battery charger?

Lead-acid batteries and lithium-ion battery chargers have different charging control methods. Since lead-acid battery chargers are generally configured in two-stage or three-stage charging mode, the voltage grades of lithium-ion batteries and lead-acid batteries do not match. There are also many types of lithium-ion batteries, and the battery performance and battery protection board parameters are probably not communicated. Therefore, lithium-ion batteries do not communicate like lead-acid batteries, and there are universal battery chargers. Generally speaking, lithium-ion batteries are equipped with special chargers when they leave the factory. In order to protect the lithium-ion battery, a special charger is required. Li-ion battery charging control is to charge according to a constant current first, and then when the battery voltage rises to 4.2V, the voltage does not rise again, and the charger detects the current. If the current is less than a certain value, the charge is completed. Lithium batteries are sensitive to overcharge, so the protection circuit is huge. The highest charging rated voltage for a single battery with a nominal 3.6V is 4.2V, and the upper limit of the allowable error is not more than 1%. The ideal charging current for lead-acid batteries is pulsed. For pulse charging, the 50-60HZ mains power supply we use is directly rectified and unfiltered pulsating DC charging. Because the self-discharge rate of lead-acid batteries is relatively large, when recycling power frequency charging , Generally use the constant voltage charging method. The lead-acid battery charger organically unites the high-frequency switching power supply technology with the embedded microcomputer control technology, uses intelligent dynamic mediation technology to optimize the charging characteristic curve, and effectively prolong the service life of the battery. It recovers the four-stage charging method of constant current/W stage/constant voltage/small constant current, which has the characteristics of high charging efficiency, high reliability, light operation, light weight and small size.
