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 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.

What is the life expectancy of a Bess battery?

The the life expectancy of a BESS battery is generally expressed in terms of the number of cycles. HT INFINITEPOWER energy storage systems generally use LFP batteries with a capacity of 280AH or above. In an environment of 25 degrees Celsius, the cycle life ends at 70% of EOL up to 4,000 times.

What drives battery life expectancy?

Battery life expectancy is mostly driven by usage cycles. As demonstrated by the LG and Tesla product warranties, thresholds of 60% or 70% capacity are warranted through a certain number of charge cycles. Two use-scenarios drive this degradation: over charge and trickle charge, said the Faraday Institute.

How many cycles a day should a battery storage system run?

A quality battery storage system should be able to manage 6,000 to 10,000 cycles before you start to see a dip in its capacity. At one cycle a day, that’s roughly 15 years plus. It’s worth noting that the frequency of cycles you get through varies depending on the energy consumption patterns of your home.

What is a good warranty on a battery storage system?

A good warranty gives you confidence in your product. It also means your purchase is protected in case something goes wrong. Most battery storage system makers offer a standard 10-year warranty that covers defects and malfunctions, provided that the battery has been used as intended.
