Why Choose Zeiss?

Battery manufacturers ship out new batteries at 80%  capacity rating, All lead acid batteries are subject to sulfation in as little as 24 hours of non-use. The rate of self discharge of a AGM is about 3% per month (the higher the temperature the quicker the self discharge).  So under the supposition the batteries were manufactured in USA or China and they took a boat or truck ride to the main distribution center in the USA, then to the distributor where the end user procured the batteries, we can assume that process might be 1-4 months and that a significant self discharge occurred creating  sulfation.  This becomes a huge problem when batteries are used in a bank setting such as 4 eight D’s in parallel or series. Additionally most charging systems undercharge the bank, producing poor performance and a shortened battery life.  The end user is frustrated, disappointed, and ultimately paying a higher price.

The Zeiss Advantage Option optimizes the batteries by keeping them all in family (98 –125%  of capacity ).  A battery bank is just like a chain “only as good as it weakest link”

  •  First we check the impedance of the battery
  • Then we perform a capacity check ( 25 amp draw to 1.75 volts per cell )  
  • Then we condition the battery with the impact charger, the only recognized de-sulfation system by the US Navy.
  • Then we charge battery with a constant potential charger for absorption charge to see if the current tapers down while monitoring  temperature differential between terminals and overall heat of battery. etc…
  • Then we rest battery for a least 24 hours and check Open Circuit Voltage ( OCV ) and impedance
  • Then we randomly audit batteries with a full capacity check before offering for sale
  •  We Warranty our batteries
