How long do Inverter Batteries last?

On average an inverter battery should last upwards of 5 years. This greatly is affected by the usage. This guide can answer all of these questions and more! We’ll also discuss which types of inverter batteries have the best overall life. And, of course, we’ll cover how to maintain your inverter and battery.

What is battery shelf life?

Battery Shelf Life is the time an inactive battery can be stored before it becomes unusable. It is usually considered as having only 80% of its initial capacity. The conditions under which a battery is stored either by the dealer or the user will determine its shelf life and in turn, eventual lifespan.

How long does a battery last?

Keeping in mind the high cost of batteries and the short period that the manufacturer’s warranty covers the battery (Warranty periods for batteries last for just twelve months.), it is important to know the best battery choice for your power needs and how to effectively manage performance.

What is a battery cycle life?

The cycle life can then be defined as the number of charge and discharge cycles that can be achieved before a battery reaches the end of its useful life. Each charge and discharge cycle, is accompanied by a slow deterioration of the chemicals in the cell. Of course, the user will not be able to tell.

How does depth of discharge affect battery life?

As stated above, cycle life decreases with increased Depth of Discharge (DOD). In fact, many inverters will shutdown when their batteries are being discharged below their depth of discharge because the batteries may be permanently damaged if fully discharged. Deep discharge inevitably lower the lifespan of a battery.

How does temperature affect battery life?

Storing batteries under high temperatures seriously affects the battery life. The temperature under which the battery is ‘shelved’ affects both the shelf life and the lifespan as well as charge retention. Heat is the enemy of the battery.
