Can a lithium battery charger charge a UPS lead-acid battery?

Because UPS lead-acid battery chargers are generally set to two or three stage charging mode, the voltage level of lithium-ion batteries and lead-acid batteries is not the same. And there are many types of lithium-ion batteries, UPS power battery performance and Lithium Polymer Battery protection panel parameters may be different. So Li-ion batteries don't have universal chargers like lead-acid batteries. Typically, Li-ion batteries are supplied from the factory with a specific charger. To protect lithium-ion batteries, use a special charger.

Lead-acid battery chargers to overcome the large internal resistance of lead-acid, in constant current charging voltage increased by about 5%, that is, you choose the same voltage charger to lithium-ion battery power supply, the voltage will be slightly higher, because the internal resistance of lead-acid is large, constant current charging to achieve efficiency is at constant current constant voltage increased, This is bad for lithium-ion batteries.

The internal resistance of Lithium Iron Phosphate Battery is low, for example a 13 series lithium-ion battery is 48 volts, the cut-off voltage should be controlled at 54.6 volts, and the constant current cut-off voltage of lead-acid batteries is 57.9 volts, a few volts higher. Of course, lead-acid Ups Batteries can be used if they are modified to charge Li-ion batteries, such as removing the low constant voltage phase circuit and pulse circuit.

Lead acid battery charging control and lithium-ion battery is completely different, the voltage may also be very different, do not use the wrong. The individual voltage of the lead-acid Ups Battery is 2V. Choose the right charger according to the voltage. The individual voltage of the lithium-ion battery is 3.63.7V. The charging control is to charge the battery first according to the constant current, and then when the battery voltage rises to 4.2V, the voltage will stop rising. The charger detects the current and if it is less than a certain value, the charging will stop. Input voltage: 100-240V, input frequency: 50-60HZ, single battery charging voltage: 4.2V.

Li-ion battery chargers are chargers specially designed for charging Li-ion batteries. Lithium-ion batteries have higher requirements for chargers to protect the circuit, so lithium-ion battery chargers usually have higher control precision and can charge lithium-ion batteries at constant current and constant voltage. The charger's operating selection should match that of the battery being charged. If the charger works in the state of lithium-ion battery and to be filled with nickel-metal hydride or nickel-cadmium battery, the battery is not satisfied, will greatly reduce the working time.
