Each has advantages and disadvantages.
With the same volume, the capacity of lithium batteries far exceeds that of lead-acid batteries, so the battery life is longer. And lithium batteries are lighter. This can make the product design more compact and smaller.
And the silent consumption is low and the number of charge and discharge cycles is high.
However, lithium batteries have strict current and voltage requirements for charging and discharging. Therefore, if used inappropriately, the battery may be damaged initially, or in the worst case explode and deflagrate, thus endangering the safety of people and property.
The electrical performance of lead-acid batteries is lower than that of lithium batteries, but the voltage and current requirements of charging and decharge are not high. It is also less likely to cause explosion accidents. However, if it is left in place for too long after use, it will be seriously damaged or even discarded. If it is not charged for a month, its lifespan will be shortened; if it is not charged for three consecutive months, it will be scrapped.
