How Long Does a Home Battery Last and Is It
A home battery backup can keep your essentials running during a power outage, but how long does it actually last -- and is it worth
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.
No matter how you use it, there are ways to help. One factor affecting battery life and lifespan is the mix of things you do with your device. “Battery life” is the amount of time a device runs before it needs to be recharged. “Battery lifespan” is the amount of time a battery lasts until it needs to be replaced.
Just like your smartphone battery, home batteries gradually lose their ability to hold a charge over time, meaning reduced efficiency and more frequent recharges as the years go by. Understanding their lifespan and maintenance needs can help you get the most out of your investment. This behavior isn't exclusive to just your smartphone battery.
The most common types of home batteries, typically made of some sort of lithium-ion chemistry, degrade over time just like any other battery. Each time you charge and discharge your battery, it loses some of its capacity to hold a charge. It's so inconsequential that you won't notice it at first.
