EBAY UK’s BEST SELLING BATTERY RECONDITIONER DESULFATOR

The Battery Extra is designed to extend the cycle life and recover old or weak lead acid batteries, typically used in, boats, motorhomes, mobility vehicles, large trucks, small solar and wind systems that are sulphated. It will work on any lead acid battery or battery pack of 12 volts or 24 volts up to 500Ah.

It is EMC tested to European standards and so will not interfere with any other electronic devices you may have fitted. Its compact size makes it very simple to fit via ring or clip connectors supplied with each unit. The Battery Extra is the only desulfator approved for sale on the Caravan and Camping Club website.

We are so confident in the ability of the Battery Extra to improve your batteries capacity we offer you a 100%, 90 day full money back guarantee, including the return costs. So in effect you are getting a free trial of our product, no ifs or buts, if it does not work for you, we give you your money back.

This is not a short term improvement; once your batteries have been recovered it will continue to work, substantially extending the life of your batteries by keeping them in top condition.

This is the very latest design in battery regeneration products, housed in an aluminium corrosion resistant case designed to dissipate the heat generated by the recovery process. The Battery Extra creates up to 10 times more current than many of the cheap plastic cased products you see on eBay.   If you see a desulfator built with a plastic box, it cannot possibly be powerful enough to be effective.

This product works, see the customer comments below and our feedback, now you can try it for yourself.  

Note: The battery Extra is not a battery charger, it works in conjunction with your existing charger to maintain your batteries in top condition.

                                                                             What the battery companies won’t tell you.  

Replacement batteries cost a lot of money and everybody knows that batteries wear out over time. What most people don’t know is that 75% 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; in effect this will reduce your battery costs by 50%.  

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 can cost upwards of £100. You will also see these pulse circuits or pulsers advertised from around £15, they do help a little, but don’t fully solve the problem. In effect all 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. As they generally only work whilst the battery is being charged they can never fully recover a sulphated battery or protect a battery fully from sulphate build up, the high voltage spikes they generate can also damage the battery in the long term. 

                                                                                            How the Battery Extra works  

The Battery Extra 12/24 was developed to fully clean both the negative and positive battery 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 12 or 24 volt 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 desulphate 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 builds up on both the negative and the positive plates 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. Ensuring that you keep, or return, your batteries to their maximum capacity. It works during both charge and discharge cycles 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.  

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 could substantially increase life of good batteries.

Customer Comments

Just had to let you know, after taking your advice I managed to get my old Ebike batteries working again using your battery extra, it took some time but they are almost up to full capacity. Not bad for a set of batteries that had been unused for 8 years. BW London 

Although we spoke recently,i would like to ask if i can give a testimony ? so now less than a week my 66 ah sealed lead acid batterys on your unit that were only giving a known discharge rate to me that worked for 46 mins are now giving 1 hour 14 mins so although it seems like a majic box that you cant see working it really seems to be doing something effective !!!!! thats 28 mins more over a week of regular drops then re charges !!! 28 mins more already at one week is amazing !!!!!! K  UK 

After 12 Rounds And Recharges My 2012 Trojans Are Like New Again AAAAA Great. Keith Queensland

 I was very sceptical when I ordered, knowing that there was a money back guarantee, I decided to give it a try. I have 4 x 6 volt batteries in my motorhome, all had very poor sg readings. After using it for 5 weeks, all the batteries are now reading close to as new specification. I am so pleased with the results. Thank you. DC Birmingham 

OK, results so far, we have tried to recover 7 car batteries from our scrap pile, 6 recovered good enough to use, 1 still dead. GP London 

Dan you talked me into it, well you were right, it works. Four weeks and the batteries are like new. Max 

I have used one on my battery bank which has 2nd hand batteries and it has made a huge difference in there storage capacity. AM 

Fast delivery good communication and have seen an improvement in capacity in only 48 hours of use. Bernie Peterborough 

Great seller, Customer support is priceless. Streetmech 

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 

Good morning congratulation on your excellent product and service, Jim. Essex 

We tested with old car battery for very long time and we found the battery we saved looks similar as new battery with internal resistance, the result is good! Best regards DR 

What a great piece of kit.  My batteries were bone dry. Filled up with distilled water.  Put on charge with your device.  Took about ten cycles, then whoop saved all four of my leisure batteries.  Awesome pal.  Baz Coventry

Model: Battery Extra 12-24 FAQ

What size of batteries will the Battery Extra work on?

The Battery Extra 12/24 will work on all 12 volt and 24 volt lead acid battery packs up to 500 Ah. We have other models designed to work on 36 and 48 volt batteries, and battery packs in excess of 500 Ah. For information on these models and prices see our other listing on eBay, send us an eBay message, 

 Is the Battery Extra tested to EU standards?

The Battery Extra is CE marked and has been fully tested in the UK and complies with all necessary standards, including European Union Directive 2004/101/EC ESA Radiated Emissions, for the safety of any other electronic devices fitted to your system you should check that the desulfator you are considering has passed this important European test.

Will it work?

On new or sulphated batteries it WILL work every time. The Battery Extra will not work with batteries that have damaged cells or sealed batteries that have dried out, but this is the best bit. We offer a 90 day 100% full refund of your payment if it does not revive your batteries, including the return postage cost. So you have nothing to loose and everything to gain. See the testimonials.

How well will it work?

To be truly effective a desulfator need to combine a high power output with the ability to produce a wide range of frequencies. The Battery Extra desulfator has an external heat sink for cooling because the electronics need the cooling area to handle its high power output. It is 10 times more powerful than the cheap alternatives you will see on eBay. If you see a desulfator built with plastic box, it cannot possibly be powerful enough to be effective.

How long will it last?

The Battery Extra desulfator is built to last, made from the best available electronic components and housed in a corrosion resistant aluminium case. It will not break if dropped or hit. The electronics are fully protected, durable, and it comes with a 3 year warrantee.

So what are my choices?

Ignore this listing and keep lining the pockets of the battery companies... This is not very sensible.

Spend £15 to £20 on a cheap plastic product that claims to be a desufator but is in fact a simple pulse circuit that is already built into many battery chargers, is not CE marked or EMC tested, and won't work long term... That's just a waste on money.

Invest £89.00 in a fully tested, CE marked, state of the art product that is proven to work and can be fitted to any 12 or 24 volt lead acid battery pack up to 500 Ah... This makes a lot sense to us.
