Lifespan 14 year Battery

While it’s true that lithium batteries often have a higher upfront price point, they offer a much longer lifespan than lead-acid batteries. In other words, the age-old adage, ‘you get what you pay for,’ rings true. A single lithium battery often lasts 10 times longer than its lead-acid counterpart, on average. Measured by cycle life, or how many times a battery can be drained and then recharged before it needs to be replaced, lithium batteries offer a 5,000 to 10,000 cycle life when discharged up to 80 percent. AGM batteries, on the other hand, might be capable of 400 to 1,000 cycles, depending on their quality, maintenance, and depth of discharge. If you cycled your lithium battery once a day, it would offer more than 14 years of life, while a standard lead-acid battery often lasts less than 4 years. While AGM batteries often last longer than other lead-acid batteries, their lifespan still pales in comparison to all types of lithium batteries. If you’re living full-time in an RV and charging your batteries every single day, then you will go through lead-acid batteries much faster than lithium. You might even need to replace your lead-acid batteries every year depending on your depth of discharge and maintenance habits. Lastly, one of the best ways to determine the minimum lifespan of the battery you are considering is to take a look at the battery manufacturer’s warranty.
