PROOF OF PURCHASE IS REQUIRED
Tire Patrol batteries can last 1+ years if the sensors are threaded on and never taken off. However, if you take the sensors off anytime you're going to be somewhere for a week or longer then the batteries can last 2+ years.
What do you need to do?
When the batteries need to be replaced, you simply e-mail a copy of your original receipt for your original sensors to firstname.lastname@example.org and once we receive the e-mail we ship you new sensors for $20/sensor.
After you complete the purchase of the replacements, email the receipt to email@example.com.
