They are not interchangeable. The charging voltage change curves of the two are different. Lithium batteries have relatively sophisticated charge and discharge protection circuits, and it is preferable (and not recommended) for lithium batteries to be completely discharged, that is, recharged. after a power outage, which may delay the memory effect. However, lead-acid batteries must be float charged and cannot be depleted for a long time, otherwise the battery will be seriously damaged.
Can lead acid batteries and lithium batteries be used interchangeably if they have the same voltage
Introduction Can lead acid batteries and lithium batteries be used interchangeably if they have the same voltage and capacity? They are not interchangeable. The charging voltage change curves of the two lithium batteries have a more sophisticated charge and discharge
