Lifespan of household energy storage batteries

How long do battery storage systems last?

Let’s take a look at the average lifespan of battery storage systems and how to maximise their life expectancy. When it comes to the longevity of battery storage systems, you can generally expect them to last between 10 and 12 years. That said, some premium models can keep going for up to 15 years or even longer with the right care and maintenance.

How long do solar batteries last?

Home battery backups usually last 5 to 15 years. High-quality lithium-ion batteries may last even longer. A 10 kWh battery can power critical systems for about 24 hours during a blackout. With proper management, they can last longer. You should plan to replace batteries once or twice over your solar system’s lifespan.

How long do home batteries last?

The expected life for home batteries is usually between 6,000 to 8,000 cycles. Similarly, you might see an expected energy "throughput" listed somewhere on your warranty. This is another way the manufacturer estimates your battery's lifespan.

How long does a lithium battery last?

The storage capacity of lithium (LFP) battery systems is typically measured in kWh (Kilowatt hours), while the most common metric used to determine battery lifespan is the number of charge cycles until a certain amount of energy is lost. This generally ranges from 3000 to 5000 cycles over a battery life of 10 to 15 years.
