What is the lifespan of lithium batteries in solar container communication stations

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.

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 long does a battery last?

This generally ranges from 3000 to 5000 cycles over a battery life of 10 to 15 years. A lesser-known metric of lifespan, often only specified in the warranty document, is the energy throughput per year in MWh (megawatt hours). There is some debate about which metric is the most critical, which we examine later in this article.

Why is a lithium battery not discharged below 20% SoC?

In general, most lithium battery systems are not discharged below 20% SOC to ensure some capacity is left for emergency situations and, in some instances, to ensure the battery is operated within the manufacturer’s warranty specifications. State of health (SOH) is a percentage of how much battery capacity is remaining.
