On new or sulfated 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, 

The Battery Extra works by creating a wide range of low voltage frequency signals, that are designed to dissolve the sulfate crystals that build 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. This will ensure 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. In addition to recovering sulfated batteries, by fitting the Battery Extra to your battery or battery bank you could double life of good batteries.

"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"

"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

"Had my Battery Extra for several months now. Got it for my 48v Yamaha Golf Cart. When I bought my cart second hand I went and got a quote for new batteries as the ones in the cart would barely get me around 18 holes. Once we even had to push the cart onto my trailer. The batteries would cost me close to $1600. Didn't see much difference for a while but now I'm finishing 18 holes with the battery indicator showing just under half full. That's pretty remarkable in such a short time. The instructions did say that it may take between 1 and 20 charges to see any difference and I have to admit I thought it was a gamble to buy Battery Extra in the first place. All I did was hook one wire to one end of my four batteries and the other to the other. Very happy and so is my playing partner as he doesn't have to push my Cart anymore."
