Each cell provides nominally 2v each but each can provide greater amperage depending upon its construction. The thickness of the lead oxide plates (which provides the electrons) increases amperage potential while still maintaining the requisite voltage. The chemical reaction for higher amperage causes a greater loss of sulfuric acid and leads to the eventual loss of chemical-electric storage. Over time you would notice a loss of fluid level in one or two cells, were you to crank your engine longer than normal. If, per se, you had to crank the engine for 15-20 seconds prior to ignition, one or two cells would have significantly higher fluid loss over time than the remaining cells. I cannot recall which cells, but prior to maintenance free batteries I usually had to add fluid to at least one cell on batteries I had in my old Mustang on a 6-month cycle.enzed4 said:Sorry, not understanding this. Have never heard of high-amperage or low-amperage cells. I thought all cells are the same:Batteries are typically made of six galvanic cells in a series circuit. Each cell provides 2.1 volts for a total of 12.6 volts at full charge.
How can the cells be high or low amperages, if they're all the same? (not confusing volts and amps)
