Although Ive been changing the cheap batteries before, how long can the battery be prolonged by the desulfator ?
The cheap battery also can be prolonged. If we compare the high quality battery and cheap one, the cheap battery might be short life than the high quality one because of the element plates’ quality. If the element plates of the battery are broken, it’s time to change the battery. So you can use the battery until it’s broken by the desulfator.
