What is the difference between lithium battery and lead-acid battery charger? Can the chargers of lithium battery and lead-acid battery be shared? The difference between lithium battery and lead-acid battery is that they use different data, discharge principle and function. Lithium battery has a larger storage capacity or longer service life. Unlike lead-acid batteries, lithium batteries have universal battery chargers. Generally speaking, lithium batteries are delivered with special chargers. In order to protect lithium batteries, special chargers should be used.

What is the difference between lithium battery and lead-acid battery charger?

The charging control methods of lead-acid battery and lithium battery charger are different. The voltage level of lithium battery and lead-acid battery is mismatched. There are many kinds of lithium batteries, and the battery functions and parameters of the battery protection panel may be different.

Lithium battery: The lithium battery charging control is to charge according to the stable current first, and then when the battery voltage rises to 4.2V, the voltage will not rise. The charger detects the current, assuming that the current is less than a certain value, the charging is completed. Lithium battery is sensitive to overcharge, so the protection circuit is messy. For a single nominal 3.6V battery, the extra charging voltage is 4.2V, and the upper limit of allowable error is not more than 1%.

Lead-acid battery: Lead-acid battery, the ambitious charging current is pulse type, pulse charging is very good with the pulse DC charging of direct rectification and unfiltered of the 50-60HZ mains power supply we use (this is based on the practice of simple circuit and low cost), because the self-discharge rate of lead-acid battery is relatively high, and when power frequency charging is selected, the stable voltage charging method is generally used (also bound to limit the current).
