The comparison between LFP and SLA

	LFP battery	SLA battery	Remarks
Weight	high energy density: 110-120Wh/kg, leads to a smaller size and lighter weight	low energy density: 32-37Wh/kg	LFP battery is about 70% size and weight of SLA battery, lower the total weight of application
Cycle life	4000 cycles and more	400-500 cycles	LFP can be used for almost 10 years; SLA can only last for max. 2 years
Capacity Utilisation	80 to 100%	50 to 60%	Most lead acid batteries do not recommend more than 50% depth of discharge
Efficiency	allows for the same amp hours both in and out	voltage drops quickly and reduces the batteries' capacity while charging and rapid discharging	LFP battery has almost 100% efficiency while SLA battery has only maximum 75% efficiency
Voltage	maintain voltage throughout the entire discharge cycle	drops consistently throughout the discharge cycle.	A stable droping voltage allows for greater and longer-lasting efficiency of electrical components
Cost	Up to 8 times the cycle life compared to equivalent SLA	A low upfront cost, but a high cost of ownership in long run	Lower total cost of ownership
Environmental effect	clean technology, safer and more environment friendly	contains the heavy metal - lead
