Also, as a lead acid battery falls in voltage, it becomes more likely to sulfate, where in sulfur molecules build up on the plates, reducing surface area, capacity, and cranking power. Keep it above 12 volts and unless the temp falls very low it won't freeze. Leave one on a shelf for five years and provided it doesn't freeze or have a draw on it, it won't drop below that. Lowest any lead acid 12 volt battery (AGMs and Gels or so called 'dry cells' are all lead acid, also AGM and Gels are very different) should every get is about 10.5 volts.
