Are you in the market for a back-up power source? If so, you might be wondering; how long do generators last? This guide will look at the lifespan of power generators and provide tips on ensuring they last as long as possible.

The first thing to know about generators is; when judging lifespan, you must understand what factors contribute to a unit’s durability. 

Learn everything about the average life of a generator, the determining factors, and how to buy a long-lasting unit.

How Long Do Generators Last?

On average, a generator will last anywhere from 10 to 15 years before needing replacement. However, some units can last up to 20 years or more with proper maintenance.

A unit’s lifespan depends on several factors, e.g., how often it runs, maintenance, the quality of its parts, etc. A generator that runs infrequently and is well-serviced can last for decades. However, a unit that runs frequently without proper care will begin malfunctioning soon.

What Factors Determine a Generator’s Lifespan

Several factors impact a generator’s lifespan. The type, how often it runs, fuel quality, and the environment can all impact durability. But regular maintenance and proper storage can also help extend its life.

Other factors include:

Diesel vs. petrol

Diesel generators last longer than petrol types. Ulike the latter, Units with a diesel engine are less susceptible to damage or wear.

Frequency of use

The higher the frequency of use, the greater the chances of premature failure. 

But the vice-versa is also true:

If you don’t use it regularly, the output can become clogged. Residue blocks fuel lines causing other parts to degrade and leading to blockages. To prevent this, turn on your power source at least once a month.

Load size

The load size refers to the number of devices you can power with a generator.

Overloading reduces your machine’s life. As the load size on a generator increases, so does the stress on the generator components. 

Over time, this can lead to a reduced lifespan. To avoid such problems, always keep the load size within the maker’s recommended limits.

The sturdiness of build

The sturdiness of build depends on the construction material of the generator, plus how well it was built. A sturdy unit will last longer than one made of poor-quality materials.

Maintenance and user habits

Well-serviced and maintained generators last longer than units that go months without service. Your habits will determine how long your machine lasts. 

Here are some dos and don’ts for generator owners.

  • Proper storage and supervision are essential to prolonging its lifespan.
  • Always follow the operator’s manual when using and caring for the machine.
  • Avoid using the unit in extreme weather conditions.
  • Be sure to keep the generator clean and free of debris.

Lastly, never overwork your unit by running it for extended periods.

Quality of Fuel

The quality of the fuel you use in your generator can have a significant impact on its lifespan. If you use low-quality fuel, it can cause the engine to wear out more quickly. 

Additionally, using low-quality fuel can also lead to more frequent maintenance issues. Always use only high-quality fuel in your unit to help preserve its life.

Points to Check When Looking for a Durable Generator

Before you buy a unit, always check the following points:

  • The seller’s warranty. An extended warranty period means the makers trust their product’s quality.
  • Price. Expensive generators are not always the most durable. But the price is an excellent starting point when shopping. Remember, the prices depends on many factors, such as size, the power output, and the brand/maker.
  • Check reviews. There are plenty of online reviews on generators. User comments can give excellent clues about a product’s quality and help you make informed decisions. 
  • Ask an expert. If you have any doubts about your purchase or want to know more about its features or benefits, ask an expert before buying one.

  • Second, it is less likely to break down, meaning you won’t have to suffer disappointments as often. 
  • Third, it operates efficiently, ensuring compliance with emission regulations.

Finally, a generator with a long lifespan is a wise investment. It will save you hundreds of dollars in the long run.

Final Words

There’s yet to be a definitive answer when it comes to the life of a generator. Different models and brands have different lifespans and warranty offers to choose froom. However, a unit can last for many years with proper care and maintenance.

As a baseline, most power generators go upto about 10 to 15 years. However, some can run longer–up to 20 years or more. But the older a unit gets, the more you might have a problem with it.
