How long does a home battery last?

What affects how long it lasts?

Several things affect the life of a home battery. Here are five that matter most:

1. Types of home battery: there are various types, each with its own characteristics and life. LiFePO4 batteries are known for their long life and high efficiency, and they are not flammable. They stand higher temperatures without being damaged and last 10 to 20 years on average. We always offer a LiFePO4 battery.
2. Number of charging cycles: the life of a battery is largely decided by how many charging cycles it can go through, which means how often it can be fully charged and discharged. The more cycles, the longer it lasts. Our AlphaESS battery, for instance, is rated at 10,000 cycles.
3. Storage capacity: how much energy the battery can hold matters too. A larger capacity means fewer charging and discharging cycles, which helps it last longer.
4. Temperature: the temperature around the battery plays an important part. Heat degrades the chemistry, so it is important to put the battery in a cool, stable place, away from sources of heat.
5. Full charging and discharging: it is best not to keep a battery at 100% all the time, because that can damage it. To extend its life we would also advise never letting it fall below 20%.

Being aware of these things helps your battery last longer and gives you more out of it.

What is the payback time?

Buying a home battery is an investment, and you naturally want to know when it pays for itself. With the technology available today a battery can make a real difference to your energy costs.

Depending on what you use and on the capacity and cost of the battery, you can expect the investment to pay for itself within 5 to 10 years. That is an estimate: the actual payback time varies with the type of battery and how it is used.
