How often do I need to replace the battery in my suction unit?

The type of battery you have will determine how often you need to replace it.

Sealed‐Lead Acid ‐ We recommend replacing the battery after 3 years or when it shows signs of losing capacity.
Alkaline ‐ Do not use the battery after the

“USE BY” date on the battery label.
If you would like to test the capacity of your battery, we’ve created a helpful battery test video for you here.
