lead acid maintenance free battery MAGIC EYE

The function of the Magic Eye® state of charge battery indicator is based on the specific gravity of the sulfuric acid or electrolyte. When a battery is charging, the change in the density of the acid is a little delayed as compared to the actual state of charge of the battery. However, the battery indicator should show green once the battery is back to 100% state of charge. There may be several reasons as to why it is not showing green: 

1. If the battery was allowed to remain in the dis-charged state for a great length of time, the battery may in fact be bad and the battery indicator will not show green because the electrolyte has not reached the proper specific gravity. The specific gravity of the electrolyte is the most accuarate method of measuring state of charge. 

2. The acid in the battery is "stratified" meaning that the heavier acid has sunk to the bottom and the lighter water is floating near the top. This happens with batteries that have sat for a long time in the discharged state. Normally, re-charging will stir the electrolyte make it more homogeneous. 

3. There may be a small piece of battery separator material preventing the green ball from floating up. 
The best thing to do is gently rock the battery back and forth. This will mix the electrolyte and will most likely free the green ball to float up "IF" the specific gravity of the acid is dense enough. 
Keep in mind that even though the Magic Eye®is located in only 1 of 6 cells, testing conducted by a major OE car company proved that the battery indicator accurately indicates the state of charge of the entire battery.


  1. Relicell Solar Gel batteries provide a much higher cyclic life compared to the AGM VRLA batteries and operate better in a partial state of charge and in high ambient temperatures.

  2. Superb and accurate information. Thanks.


  3. [Last Chance] Do this to bring any old battery back to life - just like new


    I’m not sure if you saw my last email but time is running out on this…

    There’s a new way to bring nearly any type of old battery back to life it’s just like new again.

    This method works with nearly ANY type of battery out there ...and it’s simple and quick.

    But today may be your last chance to learn how to do this simple method…

    >> Click Here To Watch a Presentation that will show you how this is now possible <<

    In the presentation, you’ll learn how to bring car, phone, and laptop batteries back to life.

    This simple methods even works with solar/off-grid, marine, golf cart, and forklift batteries. Plus, many more!

    With this secret method, you won’t have to buy new expensive batteries anymore. You can just recondition your old, used batteries and save money!

    So really …don’t miss out on seeing this. This presentation may have to come down within the next hour.

    P.S. You learn why Tom can’t teach everyone how to bring their old, dead batteries back to life again in the new presentation. The end of the presentation is pretty shocking too…
