Overview of Mercury 12/220AMPS Tubular Batteries:

Mercury 12/220AMPS Tubular Batteries create electron flow in a circuit by exchanging electrons in ionic chemical reactions, and there is a limited number of molecules in any charged battery available to react, there must be a limited amount of total electrons that any battery can motivate through a circuit before its energy reserves are exhausted. A battery with a capacity of 1 amps should be able to continuously supply a current load for exactly 1 hour, or 2 amps for 1/2 hour, or 1/3 amp for 3 hours, etc., before becoming completely discharged. In an ideal battery, this relationship between continuous current and discharge time is stable and absolute, but real batteries don’t behave exactly as this simple linear formula would indicate. The key features  that makes Mercury 12/220AMPS Tubular Batteries last longer when using it are: Unique patented alloy composition, Void free, uniform grain structure, Extremely high purity, corrosion-resistant proprietary spine alloy, Proprietary spine design ensures uniform distribution of positive active material, Extra-strong, flexible oxidation-resistant gauntlet for higher performance and extremely long life. And its highly puncture-resistant DARAMIC-USA separator, Equally spread positive active material, Better and quick charge acceptance. Designed to have a life of over 1250 cycles at 80% Depth of Discharge (DOD), Extremely high purity, corrosion-resistant proprietary spine alloy composition ensures longer battery service life. Manufacture of spines using HADI high pressure casting machine, helps maintain void free and uniform grain structure. Tubular plate construction ensures uniform distribution of positive active material for extremely long life and superior performance. Highly puncture-resistant polyethylene separator minimizes the possibility of internal short circuits. Balanced plate design for improved charge acceptance & excellent deep discharge recovery. Inter partition connection ensures the lowest internal resistance and excellent charge acceptance. Sleek appearance in sealed plastic housing with minimum footprint. Level indicators for easy maintenance. It's all for the user's benefit. Therefore, when amp-hour capacity is given for a battery, it is specified at either a given current, given time, or assumed to be rated for a time period of 8 hours. For example, an average automotive battery might have a capacity of about 70 amp-hours, specified at a current of 3.5 amps. This means that the amount of time this battery could continuously supply a current of 3.5 amps to a load would be 20 hours 70 amp-hours/3.5 amps and this Mercury 12/220AMPS Tubular Batteries will supply a load for like 40hours. For secondary cells, the amp-hour rating provides a rule for necessary charging time at any given level of charge current. For example, the 70 amp-hour automotive battery in the previous example should take 10 hours to charge from a fully-discharged state at a constant charging current of 7 amps.
