Is there a major difference between lithium and deep cycle lead acid batteries with respect to battery life versus amount of discharge per usage or is it a wash

• irq 9y ago
  There are indeed several major differences. The first one that comes to mind is to get the most cycles out of a lead acid battery, they recommend not discharging it below 50% capacity. Lithium ion batteries are usually good to 85% - 90% discharge.

    And on the other hand shouldn't be fully charged. Only going to 90% capacity does wonders for their lifetime.

      How do they compare on temperature ranges?

      Yes, but you're still talking hundreds of charges to 100% for a Li-ion before you lose capacity. A regular charge to 90% and then only charging to 100% on the odd occasion you need the little bit extra gives you the best of both worlds. Do even a handful of deep discharges on a lead-acid battery and you'll kill it.
