Lead Acid Battery & Lithium Battery

The comparison between lead acid battery and lithium battery is explained here.

Parameters	Lead – Acid Battery	Lithium Battery
Charging efficiency	Low – only 70%	Fast charging, it can be charged 50% in just 30 minutes
Weight	Approximately 30 kg per kWh. The weight of lead acid battery is almost three times to that of lithium battery	Approximately 9 kg per kWh
Maintenance	High maintenance cost	Low maintenance cost
Battery life cycle	500 – 1000 life cycles	1500 – 2000 life cycles
Safety	It discharges gas in the atmosphere during charging therefore its use is not permitted in the food industries.	No release of gas
