The maintenance of deep cycle batteries is minimal, with the exception of lead-acid batteries. Lead-acid batteries must be topped off with distilled water on a monthly basis to keep their plates submerged. In the event the plates are not replaced, a new battery will need to be purchased. When you won’t be using lead-acid or AGM batteries for a long time, you can keep them charged with a trickle charger. Due to their battery management system, lithium batteries do not require it.

There are pros and cons to each type of deep cycle battery:

1. Lithium Pros & Cons:

  • Between 2,000 and 5,000 charge cycles

Cons

  • Among deep cycle batteries, this option is the most expensive
