*Unlimited cycles warranty may not apply if the battery is charged using grid electricity. A few things that stand out: To recap, based on the manufacturer’s warranties (which tend to be conservative) you can count on today’s lithium-ion solar batteries to last at least 10 years – and perhaps up to 15.

Which battery has the longest lifespan?

How long does a lithium ion battery last?

The lithium-ion batteries that dominate today’s residential energy storage market have a usable life (70% capacity or more) of 10-15 years, which is roughly double the lifespan of the lead-acid batteries used in the past. However, the lifespan of a lithium-ion battery also depends on its chemistry and how you use it.

How long does a battery last?
