Don't test the battery, just replace it once a year. The battery will still test good and not reliably work the fob. It took me a while to learn this lesson. I kept testing batteries, cleaning contacts, etc and finally just changed all the batteries and no more problems. The fobs are very sensitive to battery voltage. The fobs with our Jeep are especially bad about being sensitive to battery voltage.
