Just helps to clean a little. In AGM batteries, I believe it will move the things around. As you go through charge and discharge, temperature changes, plates change dimension and the glass mat gets a chance to fit itself back to the plates it lies between. If gravity has pulled things to one side this helps redistribute back to original manufacture. If you have a battery tester like the CBAII, this would be a good time to check the battery. If you think about one of the applications for this battery you will begin to see that it is designed for idle periods. You will find this battery in several of the smaller, two lamp emergency lights. Mostly they just sit on trickle charge, never moving but they do cycle internal temperature and remain good for when they are needed.
