Sulfation is like a virus, if left unchecked, it spreads, so a battery left in this state is destined to live a short life. This means that the battery is always going to present starting problems, usually at the most inconvenient times. The vehicle’s charging system will therefore not deliver sufficient charge to effectively reverse sulfation in a deeply discharged battery that has developed high resistance due to a degree of sulfation. The voltage is the set parameter, and does not necessarily imply any current, as this depends on the resistance of the battery. Myth #3: The vehicle’s charging system will recharge a deeply discharged battery.įact #3: A vehicle’s charging system has been designed to supply power to the electrical system at a voltage not exceeding 14.5V. Even so, OptiMate, the manufacturer of the Battery Sitter has received letters from a number of users testifying to effective recovery of batteries left discharged (and believed to be dead) for as long as two years.

So, the degree of effectiveness of the recovery depends on how soon after the battery became sulphated that it is desulfated & recharged.

Whereas normal battery acid freezes at well below freezing point of water, the water which results from a discharged battery freezes at temperatures below 32☏ / 0☌ and expands, resulting in bent & buckled plates or at worst, a cracked casing.Īt temperatures exceeding 95☏ / 35☌ water will evaporate and the more water which evaporates, the higher the concentration of lead sulfate and the lower the chance of effective recovery. When a battery is discharged the electrolyte changes from a sulphuric acid state to lead sulfate and water. Heat is a big killer of lead-acid batteries. The extent of the damage depends on how deeply the battery was discharged, how long it was left like that, and in which average temperature. When a battery becomes sulfated it will suffer some damage / wear to the plates. However, not every ‘dead’ battery can be desulfated and neither can a desulfated battery be recovered to 100% of its previous ability. The Battery Sitter charger has a unique ability to desulfate and permanently recover batteries that have been neglected or deeply discharged. The charge retention test which follows this stage confirms whether the battery has been adequately recovered before the long term maintenance “floating charge mode cycle” engages. As part of this, the recovery continues with the subsequent unique charge & check stage which removes remaining sulfate crystals from the plates. The Battery Sitter’s unique automatic desulfation mode works like this: Once the Battery Sitter determines that the battery is sulfated it applies a voltage of up to about 20V at a controlled low current for a maximum period of 2 hours, to recover the battery to the extent that it can again accept a charge using the more normal charging algorithm. sulfated) VRLA / (including MF type) sealed batteries often develop internal resistance too high to overcome at normal charge voltages which requires an initial high voltage charge rate (up to 25V), under supervised conditions, to reverse the high internal resistance caused by sulfation on the plates.

Usually one is told that the battery has died and needs replacing and that is how this myth is kept alive. Myth #2: Once sulfated, a battery is useless and should be replaced.īatteries develop a high resistance to charging which the average (so-called) smart charger cannot overcome. IMPORTANT: To effectively desulfate a battery it must be disconnected from the vehicle wiring before connecting to the Battery Sitter. Vehicle electronics require a higher voltage than this to function so if a battery in this condition is still connected to the vehicle no electronics can be active.Įven a LCD display circuit will draw a few milli-amperes if a voltage is applied and upon sensing this the Battery Sitter will engage its normal charge mode with maximum charge voltage 14.3V. Upon connection to a battery, the desulfation mode can only engage if no current enters the battery at a charge voltage of up to 14V.Ī sulfated battery’s voltage will initially be typically in the 2 to 6V range.
