Lithium iron phosphate battery charging for 2 hours
The Stage 1 of a lithium battery can take as little as one hour to complete, making a lithium battery available for use four times faster than SLA. Stage 2 is necessary in both chemistries to bring the battery to 100% SOC. The SLA battery takes 7 hours to complete Stage 2, whereas the lithium battery can take as little as 15 minutes.
