AlesVolvo,
12V Lead Acid Batteries (LAB) can be confusing with all the numbers. Any 12V LAB has 6 “cells” each capable of a theoretical maximum voltage of 2.2 volts for a total of 6 x 2.2 = 13.2V. A fully charged battery will actually have about 12.7V. And does not matter if the battery is 140Ah or 110Ah or even 1,000Ah, it will still only be 12.7 fully charged. The Ah (Amperage Hours) are a measure of how long it will last. A 140Ah will last longer than a 110. This is why AllDodge says “larger is never an issue”. It is STILL the same voltage to your PCU. No change. The other larger numbers (800 and 1100) are the Cold Cranking Amps (CCA). The CCA is a measure of how many amps a battery can produce for a 30second period at 0 degrees Fahrenheit, before the voltage drops to an unusable level. Said differently this is a measure of how long you can ‘crank’ (key to the start positions) your car / boat before the voltage drops to low to turn over the starter and/or supply the needed voltage to things like the engine computer. Again, larger is never an issue.
Hope this helps.
