What is Desulfation?

Sources of Information

The process of sulphation occurs to all batteries almost from the day they are made, while they sit in the shop/ garage where you buy them from and even when operating in your car, bike etc. it is simply a matter of time and the usage/ charging regime it is subjected to.

We have no intention of attempting to explain the chemistry of this process, we're not qualified to do so.

Basically the pulse created by these devices will cause the lead sulphate to go back in to solution at the microscopic level. The following sites are amongst many which can be found on the Internet which offer a fuller explanation.

The phrase ‘sealed for life’ as applied to batteries can be something of a misnomer in our experience.

A battery removed from a car we own and which failed to start the vehicle one proverbial winter morning proved to have suffered serious fluid loss in three cells. Ironically the battery was translucent and thus, had we looked, this deterioration would have been obvious and preventable. Another example of the fact that most batteries are ‘killed’ by their owners rather than ‘die’.

This battery has since ‘fully’ recovered using a pulser in conjunction with a trickle charger.

Another battery in our ownership which had laid unused for some 4 years and which refused to take a charge initially and wouldn’t get near starting a vehicle has now also recovered having been subject to the same trickle/ pulse charge regime. We were using this battery in my Land-Rover during the following leaves (as well as powering an anemometer recording device most recently).

Thus we are converts to the cause of pulsers, specifically the Alastair Couper (AC) version as this is the only version of which we have any experience.

We now have a total of eight of these devices from two near original versions, through DD’s thermistor version to one with improved semiconductors, a larger output capacitor, reinforced circuit tracks and proper output mounting terminals. All combining to provide a more powerful pulse.
