How long is the battery lifespan in a solar outdoor lighting system?

Battery lifespan depends on its own mass, but also on the depth of discharge (DOD).
INLUX SOLAR's solar outdoor lighting system adopts the brand new highest quality lithium batteries with a technical solution of low battery discharge-depths (less than 50% for lithium iron phosphate, less than 40% for ternary lithium and less than 30% for gel batteries).
We can ensure the lifespan of lithium iron phosphate batteries can reach more than 10 years, and that of ternary lithium batteries and gel batteries can reach more than 5 years.
