Power boards also known as surge protectors and power strips can last from 3 to 5 years although the lifespan of the power boards can vary.
To ensure the safety of the power board, surge protector or power strip it is essential to conduct preventative maintenance regularly.
This includes checking the power boards, surge protectors and power strips for any signs of wear and tear, such as frayed cords or damaged outlets, and replacing them immediately.
Surge protectors may need replacing if they show any visible damage such as cracks, burn marks or any melted plastic or if the indicator light is off or flashing or if the outlets on the surge protector don't function as they should then it's a good idea to replace the surge protector.
It's also good to replace the surge protector every 2 o 3 years or after a significant power surge to ensure that you have a proper functioning surge protector.
Other power strips other than surge protectors can last for many years, if they are well cared for and well made and not overloaded.
The average lifespan of a power strip is 4 years, although they can last longer in some cases.
I have a power strip that is 15 years old and it's still working good but a surge protector can go bad sooner.
Surge protectors don't have an infinite lifespan.
Over time, the internal components of surge protectors that absorb excess electricity can wear out, especially after multiple minor surges that you might not even notice.
As a general guideline, consider replacing your surge protectors every three to five years.
