Technical FAQs 4

How long do solar batteries last?

The life expectancy of a solar battery depends on several factors—what kind of battery you have, how you use it, where it’s stored, and how well it’s maintained. While lead-acid batteries may only last a few years, lithium options can easily reach 10 to 15 years or more with proper care.

How do I get the most value out of my solar battery?

If you want to get the most value out of your solar battery, here are a few tips to help extend its life: Choose the right battery for your needs. Lithium batteries may cost more upfront but last much longer than lead-acid options. Avoid deep discharges when possible. Using only part of your battery’s capacity reduces strain and increases lifespan.

How long does a battery last?

Lead-acid batteries (flooded or sealed): These are the most traditional type and also the shortest-lived, typically lasting 3 to 7 years. They’re more affordable upfront but require regular maintenance and don’t hold up as well over time. When people talk about battery lifespan, they’re often referring to “cycle life.”

How long does a flow battery last?

Flow batteries: Designed with large-scale storage in mind, these use external tanks filled with liquid electrolytes. They can last over 20 years, but they’re large and expensive, making them more suitable for commercial or utility-scale systems than home use.
