battery desulfator battery reconditioner

Works to maintain and recover all types of lead acid batteries and packs from 12 volt to 48 volts that are fitted to golf carts / buggies, small forklift trucks, boats, electric cars, small solar systems, electric bikes and scooters, back-up power supplies. Good maintenance is the key to extending the life of your expensive battery packs, and fitting the Battery Extra desulfator is the simplest and most cost effective way to achieve this. This latest model, with a much smaller footprint, is very popular with ride on golf buggy users and small off grid solar systems around the world; see what our users say on the testimonial page. It is also ideal for people or companies who have various battery packs of different capacities and voltages, they wish to maintain or recover.

The Battery Extra will fully clean both the negative and positive battery plates of all the sulfate crystal build up, without the need for the damaging high voltage spikes, and return them to a fully working condition. it also to eliminate sulfate 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 12/24/36/48 volt lead acid 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 desulfate one bad battery or set, and then just move it on to the next battery.

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, it is not suitable for UPS batteries that are not cycled (charged discharged) 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 lose and everything to gain. 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. It is 10 times more powerful than the cheap alternatives you will see advertised. If you see a desulfator built with plastic box, it cannot possibly be powerful enough to be effective.

The Battery Extra works by creating a wide range of low voltage frequency signals, that are designed to dissolve the sulfate crystals that builds up on both the negative and the positive plates of a lead acid battery. It is this build up that reduces the batteries capacity. Gently dissolving the sulfate crystals back into the electrolyte over several charge cycles, 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 sulfated batteries it will not recover batteries with damaged or dried out cells. In addition to recovering sulfated batteries, by fitting the Battery Extra to your battery or battery bank you could double life of good batteries.

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.
