Replacement batteries cost a lot of money and everybody knows that batteries wear out over time. What most people don’t know is that more than 70% of lead acid batteries fail because of sulphate build up on the cells, not because they are worn out. Sulphate build up increases the internal resistance of the battery, reducing its capacity and leads to premature battery failure. Sulphated batteries can now be successfully recovered saving the cost of expensive replacements. You can also stop sulphate build up on new batteries which could double the life of your batteries. The main causes of sulphate build up on lead acid battery cells are: Batteries sitting too long between charges, storing batteries without charging, undercharging batteries, low electrolyte level and incorrect charging levels. The problem of sulphate build up on lead acid batteries has been known about for a long time, and battery charger manufacturers have been adding what is called a “pulse circuit” to their high end chargers to help overcome the problem, calling them charger conditions and charging very high prices for them. You will also see these pulse circuits or pulsers advertised from around US$15 (£20) these very low cost devices are generally built from 15 to 20 year old circuit designs (antiques in electronic terms) that are free to download on the internet, they may help a little but don’t fully solve the problem. Most of these pulse circuit devices send a high voltage current into the battery which will break down some of the sulphate build up on the positive battery plate but the high voltage spikes they generate will also damage the battery in the long term.

Glen’s batteries were losing capacity, and on inspection he found that the battery plates were sulphated, he tried to recover the situation by running a couple of equalisation charges, this did not help, and he published a video of his problem on YouTube. One of his subscribers suggested he try fitting a Battery Extra. So Glenn decided to give it a try, this is an edited video he posted showing the results of using the Battery Extra on his solar Battery bank for 3 weeks. Glenn is not connected in any way to Battery Extra Ltd. except as a customer. For full details on all of the Battery Extra models visit our

Christopher using the Battery Extra EX01

Christopher, a customer of ours in Lagos, was brought an old 12 volt battery to try to recover, it was low on water and was recording only 4 volts, and he thought it would not be possible to recover but he gave it a try anyway. This is an edited video posted by him on YouTube showing the results after using the Battery Extra. Christopher is not connected in any way to Battery Extra Ltd. except as a customer.

The Battery Extra was developed to fully clean the plates of all the sulphate crystal build up, without the need for the damaging high voltage spikes, and return them to a fully working condition. It also to eliminate sulphate build-up on new batteries keeping them in top condition, ensuring they have the maximum possible life span. It works during both the charge and discharge phase of the battery cycle. The Battery Extra can be permanently attached to any lead acid battery or battery pack. It uses a small amount of power from the battery to extend the life of new batteries. It also revives many weak or old batteries that are thought to be dead or need replacing. Alternatively you can de-sulphate one bad battery or set, and then just move it on to the next battery The battery Extra works by creating a wide range of low voltage frequency signals that are designed to dissolve the sulphate crystals that build up on the of a lead acid battery. It is this sulphate build up that reduces the batteries capacity. Gently dissolving the sulphate crystals back into the electrolyte, lowers the internal resistance of the battery, and raises the specific gravity. This ensures that you keep, or return, your batteries to their maximum capacity. It works with no need for a special charger or any external power supply. The Battery Extra will work on all types and brands of lead acid battery, including GEL, AGM, Maintenance Free, Deep Cycle, Sealed and Leisure. Depending on the condition of the batteries this can take from a couple of cycles to 20 or more. Whilst the Battery Extra is successful in recovering all sulphated batteries it will not recover batteries with damaged or dried out cells. In addition to recovering sulphated batteries, by fitting the Battery Extra to your battery or battery bank you can extend life of good batteries. What the Battery Extra battery desulfator cannot do is recover batteries that have shorted or damaged cells. We recommend that you check for damaged cells before using the Battery Extra.

‘After 12 Rounds And Recharges My 2012 Trojans Are Like New Again Great. I have also ordered another 3 of this product for friends since then and recommended this product to many others who have ordered’ Keith, Queensland ‘Hi, thanks for the Battery Extra 36/48 it is working fine and saved my golf buggy batteries. This is another order for 12/24 for my sister as she was very impressed, so all good. Thanks’ Les, New South Wales. ‘Saved me a fortune this was my last resort before I ordered new set of batteries a++++++’. Tony, England

‘Exactly 2-months since i installed the battery extra desulfator. Looks like the Battery Extra is living to its advertising. Battery imbalance seems fixed and I noticed battery bank is holding its charge better. Battery life is longer and LVD ATS is not being triggered since almost around 2 weeks now. Battery extra worked wonder’ Froilan ‘Your desulfators are working great on my clients’ old solar battery banks’ Jeff, Philippines ‘I run an off grid workshop, I thought my 2006 battery bank was down but still ok– ha ha this has shown me how wrong I was, their life without the back-up 24v genny running has nearly doubled, and run time before inverter cuts off has doubled. Superb product, Am totally amazed.’ Robin, Scotland ‘I have been using this (on my solar battery bank) for a few months now. The digital readout is clear and can be seen from across the room. This unit is well made, sturdy, easy to hook up and set up. Bottom line, I have very happy with this desulfator and this company, they are very helpful and if you contact them with questions, they get back to you with answers’. Wretha Texas

‘I am happy to confirm that the unit has returned some heavily sulphated batteries to around 80% and as such we are very happy.’ Caravan and Camping Club UK ‘I was ready to replace 3 batteries, assuming that they were defective and cost over 140 us dollars each. I have successfully rejuvenated all three batteries. Thank you for a good product’ John, Texas ‘I have been using 2 of these units for the past 6 months. One is connected to my motorhome vehicle battery and the other connected to the leisure batteries all three batteries are at least 3 years old and have been improved by the use of the units that are hard wired into the battery circuits.’ John, UK

‘A client brought in two very distressed batteries. One was at 12.2 V and the other at 8.01 V. We put them on a charger, connected a battery desulfator to each battery and used charge controllers as a load. The desulfator and charge controller served as small loads to discharge the batteries. Today we tested them with two drills with a combined total of 700 Watts and they are both working fine.’ Christopher ‘I was a bit sceptical about this, but it’s saved 2 expensive batteries already.’ Roger. UK ‘I bought a new battery for my car, last summer. I don’t drive my car much during the week and the old battery hadn’t lasted long. Recently my ‘new’ battery was failing to hold it’s charge from one weekend to the next. At £100+ for a battery for my car, I had nothing to lose by trying this ‘reconditioner’. I connected it and there’s no doubt at all that it has revived the battery on my car. I don’t know how it works; but it does. My car is a 1999 1.6 Audi A4 petrol; and this device hasn’t damaged my car.’ J.R. Richardson ‘I bought this unit, as I had a lead acid battery on a tractor that is not used too much, but failed to start after charging the battery. It was either this or a new battery & with the 60 day guarantee it is defiantly worth a try. I used the unit with a battery charger, over a 7 day period. For other reasons, I then left the battery in the tractor for a month, then tried it, it started first time. Therefore, unquestionably it had a positive effect; how long it lasts I do not know. After receiving the unit, I emailed their tech department with a couple of questions & within the day, got a very thorough response from someone who definitely knew their stuff. Update Oct 1 2015 – Battery has continually started the tractor without further offline charging. Definitely has had a positive & lasting effect.’ Gerry. Ireland
