Welcome to Courtiestown Marine - Home of the UK's No.1 battery desulfator (desulphator)/ pulser

AVAILABLE NOW - We are now selling a 24V version, in fully built, built PCB and kit form of both our Basic & 'High Power' desulphator (desulfator)/ pulser. Check out the Shop (SHOP) to order. This has been made possible with the introduction of our new PCB allowing what were previously add-on bits to be incorporated in to the PCB.

This new PCB is also allowing us to develop a 36 and 48V version of our devices.

ALSO AVAILABLE NOW - We have been selling kits/ parts to facilitate those interested in building Bob Boyce PWM3F and PWM3G based PCB's (Peswiki) along with toroids and parts over the last 3 months. Check out the Shop (SHOP) page for progress.

We also sell a range of parts to facilitate people wanting to follow both Dave Lawton's project following the work of Stan Meyer and also almost any part you could want to pursue the work of John Bedini.

In the last couple of days we have built up a prototype Dave Lawton box of electronics as per Patrick Kelly's D14.pdf. We will shortly be able to provide a kit of parts or a complete built unit - please make enquiries.

More information can be found by seeking out Patrick Kelly's excellent D9.pdf (D9.pdf - (PDF 588Kb)) and D14.pdf (D14.pdf - (PDF 257Kb)) documents.

If you can't see a part you wish for any Bedini/ Bob Boyce or Dave Lawton then contact us and we'll see what we can do, we're here to help.

If you have questions about these new lines or any of our existing pulsers then click on the link at the bottom of the page.

We hope you will find it this site's content informative. As of November 2007 we are expanding the range of products we sell and will be modifiying the site content accordingly. Rest assured we will continue to market our range of proven 'pulsers'.

Our battery desulfators (desulphators?)/ pulsers can be used as part of a lead acid battery maintenance/ equalizer/ recovery system in conjunction with conventional battery chargers (or any other method of charging batteries) to prevent premature problems or failure of battery cells, the most common cause being a build up of sulfate (sulphate). They can be used to prevent dead or flat batteries in your classic car, boat etc.

We can also supply EDTA.

The automotive magazine Classic & Sportscar tested our 'High Power' pulser in March 2005 and awarded it a 'Budget Choice' nomination. Additionally we can now report that trials of the PIC based and existing High Power Pulser conducted by Don Plisco in the USA were concluded with both devices being highly recommended having beaten the opposition 'hands down'. See the Battery Desulfator page (Battery Desulfator) for further information.

One more than satisfied customer was quoted as saying "It would seem that it does its job exceedingly well." and another "Just an update on my desulphating activities..........just to prove that desulphators actually do work. I've successfully brought back from the dead a 110AHr leisure battery. (prior to treatment).... Within a couple of hours, after being charged for 24hours, it would collapse to 10.3V o.c. After a week on and off the desulphator, it now will run three 16W fluorescent lights, a 300W inverter running a laptop and run the shower-pump and fresh-water pump when required before fading away after about 5 hours. - It doesn't all add up to 110AH, true, but it's a long way better than it was......So to sum up. Yes it really does work! As promised I'll spread the word. Best regards,"

Prospective customers might like to compare our worldwide, inclusive of postage, prices against some of our competitors!!

	Basic Kit	Basic Kit built	High Power Kit	High Power Kit built	Ready Built HP	Top end device
CTSolar	$80.95	$100.00			$124.95	$170.00
Don Denhardt	$42.00	$67.00	$62.00	$87.00
Courtiestown	$29.50	$38.50	$37.50	$48.50	$66.00	$95.50

All our units are now supplied with reverse polarity protection and, in the case of the PIC based pulsers, thermal cut-out protection as well. This means the curse of the simple battery desulfator has now been overcome and you can connect it wrongly safe in the knowledge it has only cost you a fuse!! A great peace of mind addition.

Thus our devices are now supported by both Classic and SportsCar, the results of Don's tests above and, in some cases, by repeat customer orders. Thus dare we say you can read about the rest but if you want a proven pulser desulfator/ desulphator that does what it says then buy one from us safe in the knowledge it WILL desulphate (desulfate) your batteries.

As a result of enquiries about buying PCB's for the existing kits i.e. Basic and 'High Power' we have now added the option to buy the PCB only to the Shop (SHOP) page. Similarly with the PIC based device we will be offering a stripped down kit consisting of just the PCB, PIC and inductors and the schematic. It will be down to the user to source all the remaining parts and at their own risk.

The previously available 'special introductory offer' on the PIC pulser has now been extended, see details on the Shop (SHOP) page.

In support of this new PIC based pulser we have set-up a Yahoo chat group which you can check out at http://groups.yahoo.com/group/randrdesulfatorforum/

We can offer the fully built devices both with and without the cast brass battery terminals/ crocodile clips to customer requirements. This may be of particular interest to overseas customers as it offers a saving in both cost and postage. For details on this and any other particular requirements please feel free to contact us.

Most recently we have been fielding a number of enquiries about 24V devices. We can now supply a 24V Basic and 'High Power' Pulser, development work on a 24V PIC pulser is currently ongoing.

Other devices we are looking towards developing are a battery capacity tester, a pulse charger/ demosser unit and possibly a unit to work in conjunction with such as solar panels to recharge batteries.

Other areas I'm investigating include the work of John Bedini and Bob Boyce.

The Bedini page (Bedini) shows some of the Bedini devices I have built in the last 4 years and recent evolutions of his devices do seem to hold promise of providing the means to develop useful amounts of power from batteries and allow independence from the grid. I will be posting pictures relating to my more recent investigations of the work of Bob Boyce shortly.

The electret charging system (Electret) may provide an alternative source of simple battery charging for any number of uses, again independent of the grid.
