The following points will help you perform the tests consistently and communicate with your customers clearly:
Decide where and when you want the test to take place.
At car dealerships, this might be the service drive. At a general repair facility, this might be part of an overall preventive-maintenance inspection. The important thing is to make it part of a regular routine and stick to it.
Make sure that you have a process in place for getting the printed test result to the customer.
In most cases, this will probably involve attaching the printout to the customer’s work order so that whoever is responsible for communicating the result has the required information.
If the customer has dropped off the vehicle and is not present, don’t wait until he or she has returned to pick up the vehicle.
At that point, they will most likely be in a hurry and will be more inclined to postpone battery replacement until a more convenient time. It’s important to let the customer know as soon as possible so that his or her decision will not be influenced by external factors.
The test result should be communicated in exactly the same way you would any other preventive maintenance issue.
Just as you would inform a customer of a worn belt or worn brake pads, so too should you convey the battery test result.
Again, process integration dictates that the ED-18 result be communicated at the same time and in the same manner as any other pertinent information about the vehicle’s condition.
