Technical FAQs 4

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.

What affects both battery life and 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.

How long does a battery last under warranty?

On your warranty, the manufacturer guarantees your battery will be able to deliver up to a certain amount of cycles while under warranty. 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.

How long can a car battery last?

Most manufacturers will guarantee up to at least a 70% capacity retention rate. You can still use your battery after your warranty period is up -- possibly for another five years, even. Just don't expect the battery's performance to be as good as it was when you first had it installed.
