Please note:

a) The device only works for sulfated lead acid battery charger and extend good battery life, not for bad battery.

b) Real-time voltage showing on LED tube may have 0.1-0.3v deviation from multimeter, occasionally 0.4-0.5V. This is normal, because there are difference between devices. And this will not affect maintenance and recovery function.

Features:

Maintain and revive lead acid batteries used on golf cart, electric Vehicles, motorcycle, car, trucks, boats, solar battery packs, forklifts an back-up power supplies.

It can work on all kinds of lead acid battery, and doesn’t interfere with any other electronic devices connecting with the battery pack. Our ultimate goal is to prolong battery life by maintaining good battery in great condition and reviving sulfate battery as max capacity as possible. Installing the battery rejuvenator is the easiest and most effective method to reach this goal. The newest model is more compact and sophisticated design, which is very popular with customers having golf cart, solar battery system and various of voltage and capacity battery packs. The Battery Rejuvenator can clean sulfate crystals on both positive and negative battery plates, with high-frequency pulse, to revive them to as much capacity as possible. It is also able to prevent new or good batteries from sulfate crytals, to keep them in good status, so in order to extend the expensive batteries life. The battery rejuvenator can work on charge and discharge stage of battery cycle, or works individually. It is permitted to connect with all kinds of 12/24/36/48/60/72 volt lead acid batteries permanently, which has protection mode showing ‘BL0’ while battery voltage drops below 11V, but it's better for 12V rate battery to keep it over 12V with charging. The battery rejuvenator only consume a little power of battery to maintain and revive batteries, which is much good-environmental.

Is the battery rejuvenator useful to your battery?

The battery rejuvenator can work for any good or sulfate lead acid batteries, but is not able to work with damaged or dried out cells or batteries, and it is unuseful to the battery which can’t be charged or cyecled.

The Battery Rejuvenator has alloy case heat sink for cooling, and its construction is very sturdy preventing  destroyed carelessly falling or others at using. It is much more powerful than cheap alternatives made of plastic.
The Battery Rejuvenator dissolves sulfate crystals on positive and negative plates of batteries by releasing relative-high voltage and high frequency signals, since decreased capacity of battery is caused by increasing internal resistance occurred of sulfation, to raise physical density. The device can work on charging together with charger, discharging, or individually, no need of AC power or other external power source. The battery rejuvenator can work for all bands or types of lead acid batteries, such as SLA, AGM, GEL, Deep Cycle, Dry, Flooded, Maintenance-free batteries.

The battery rejuvenator can work with charger in parallel, or not.

Recovery effect may be visible or obvious in couple use, but under most situations it would take long time to see noticeable effect. 

A word: more helpful, more use.
