Video for Battery Corrosion Cleaning on The Validator. This is a video showing how to clean the corrosion on battery contacts caused by Alkaline batteries. The Validator, from Dial-N-Document (DND) is the star of the show, being DND's Electronic Visit Verification (EVV) device. Since this device is in the field for extended periods of time, batteries may fail and require cleaning, when removed, for the device to remain viable for visit verification in the future.
2 Disposable Cups
White Distilled Vinegar
Plastic Bag (For disposal)
Remove batteries and any large debris from the battery compartment
Hold The Validator vertically so that the battery terminals with the corrosion are facing the floor. This will help alleviate the possibility that the liquid will come in contact with the circuit board inside the housing.
Dip a cotton swab in Vinegar (shaking off the excess) to clean the white powder from the remaining contacts and housing. As you touch the cotton swab to the corrosion, it should start to fizz.
Be sure to swap out the swabs often and keep them relatively dry so that there is no liquid that will get into The Validator housing.
After all of the deposits from the battery have been removed, use cotton swabs dampened with water to clean up any residue left from the cleaning process.
Use paper towels to clean up the majority of the remaining liquid
Leave the device on a flat surface with the battery compartment facing the floor for 12 or so hours so that everything will be dry on the inside before re-installing batteries and putting The Validator back into service.
The Validator was designed and built to Dial-N-Document's specifications by Honortronics Inc.
