Battery sulfation is the process of lead sulphate crystals appearing on a lead acid battery. It results from prolonged periods of battery inactivity, where the charge level gradually decays or from chronic undercharging. It can damage a battery to the point where it will no longer take charge and provide energy. Here are some effects of sulfation on your batteries: 1) Longer charging periods 2) Excessive heat build-up 3) Shorter running times between charges 4) Dramatically shorter battery life 5) Complete battery failure Well, here are a few tips to prevent your batteries from sulfation: 1) Charge your lead acid battery regularly to a full charge whenever possible. 2) Disconnect the battery when not in use. 3) Periodic recharging of the battery effectively prevents sulfation. 4) One can also depend upon anti-sulfation mechanisms called battery conditioners that send pulses to the battery terminals. In most cases, this will delay the development of the chemical reaction on a healthy battery, but the units cannot dissolve the condition once it begins.
