The different batteries and how they work!
1) Car batteries:
These are for short term high amp output to turn your cars engine over to start it. When your engine starts your cars alternator replaces that used current fast because you may just drive 2 miles and shut the car off to get gas and than have to restart it.
If your car has trouble starting the battery will die with moments.
A standard battery charger replicates your cars alternator and charges the battery up quick again (although not as quick as your alternator;
*** Not suited for deep cycle use and a standard battery charger will destroy deep cycle batteries ***
2) Marine or RV batteries:
These are actually a "hybrid", and fall between the starting and deep-cycle batteries with most be much closer to car or starting batteries.
Not really true deep cycle and have a top charging voltage of 15.5 volts.
*** Not suited for E2D’s high voltage that will destroy them. ***
3) Deep cycle:
Deep cycle batteries are designed to be discharged down as much as 80% time after time, and have much thicker plates. The major difference between a true deep cycle battery and others is that the plates are SOLID Lead plates - not sponge. Unfortunately, it is often impossible to tell what you are really buying in some of the discount stores or places that specialize in automotive batteries. The popular golf cart battery is generally a "semi" deep cycle - better than any starting battery, better than most marine, but not as good as a true deep cycle solid Lead plate, such the L-16 or industrial type.
*** Suitable for most applications that have a maximum charge voltage of 15.5 volts ***
*** Not suitable for E2D’s High Voltage output as it will destroy the battery ***
4) AGM Deep cycle:
AGM, or Absorbed Glass Mat Batteries
A newer type of sealed battery uses "Absorbed Glass Mats", or AGM between the plates. This is a very fine fiber Boron-Silicate glass mat. These type of batteries have all the advantages of gelled, but can take much more abuse. These are also called "starved electrolyte", as the mat is about 95% saturated rather than fully soaked. That also means that they will not leak acid even if broken.
AGM batteries have several advantages over both gelled and flooded, at about the same cost as gelled:
Since all the electrolyte (acid) is contained in the glass mats, they cannot spill, even if broken. This also means that since they are non-hazardous, the shipping costs are lower. In addition, since there is no liquid to freeze and expand, they are practically immune from freezing damage.
Nearly all AGM batteries are "recombinant" - what that means is that the Oxygen and Hydrogen recombine INSIDE the battery. These use gas phase transfer of oxygen to the negative plates to recombine them back into water while charging and prevent the loss of water through electrolysis. The recombining is typically 99+% efficient, so almost no water is lost.
And, since the internal resistance is extremely low, there is almost no heating of the battery even under heavy charge and discharge currents. The Concorde (and most AGM) batteries “HAVE NO” charge or discharge current limits.
