A dead cell in the battery can certainly cause problems, have the battery tested along with the rest of the charging system. It could be that the battery is just old and tired. On the other hand, if the charging system isn't working right the battery will not be able to store enough current. Remember that a battery is just a storage device that holds a large amount of electrical energy so that you can start the engine. The battery is a chemical device and like all things in this world, they do wear out. A charging system test will certainly tell you what's going on.
Chemical energy is converted into Electrical Energy. Cause: Oxidation , ions
Too much current was flowing which caused an overheating problem. Can be the battery has a dead cell, or you reversed the cables.
Low voltage from the battery, can be caused by a faulty battery or an alternator that isn't functioning properly. Bad starter Corroded battery connections or other electrical connections.
Voltage fluctuations in a 2003 Jeep Grand Cherokee can be caused by issues such as a failing alternator, loose or corroded battery connections, or a malfunctioning voltage regulator. These problems can lead to insufficient charging of the battery, resulting in low voltage and ultimately causing the engine to stall. Additionally, electrical components drawing excessive current can exacerbate the situation, further destabilizing the voltage level. Regular maintenance and diagnostic checks can help identify and resolve these issues.

it is caused by the alternator voltage regulator switching on and off to charge the battery, this problem is encountered on many makes of car, you may not of noticed it before prior to exchanging the battery.
Check Voltage regulator----Maybe overcharging battery. Both shortening life cycle and allowing too much voltaqe to starter
As with many electronic devices they can merely fail over time. I have heard it said that jumping the battery can cause the ECM to fail, I don't know that to be true. Too high a battery voltage could cause failure of the ECM. That might be caused by the alternator putting out too much voltage when charging the battery.
If a 1994 Cadillac DeVille's battery volt reading is high, it typically indicates that the charging system is overcharging the battery, which can be caused by a faulty voltage regulator or alternator. This can lead to potential damage to the battery and other electrical components, as excessive voltage can cause overheating and premature failure. It's important to have the charging system checked promptly to prevent further issues.
Voltage drop is caused by circuit resistance
check for proper grounding, bad wiring. Check voltage with a voltmeter in different places to see where you are losing it. Alternator, battery, at the headlight connection, fuse box & relay (if applicable). could also be caused by belt slippage, or lights with a higher wattage than recommended.
A battery may have a small voltage potential but not the "CAPACITY" to deliver amperage. For instance if you were to measure the voltage at the battery terminals with a Volt/Ohm meter (VOM), you would get a reading of say 12+ volts. As soon as you turn something on such as a headlight or heater motor, the voltage drops down or goes to 0 volts, you would have a battery that is bad or under capacity. It also could be caused by a "BAD CONNECTION" such as a loose battery post clamp. It is critical that when you test a battery, you test it at the battery posts themselves without the cables attached to rule out a bad connection. This is done with a battery load tester. As many people do not have the equipment to test a battery, batteries can be tested at many automotive parts retail outlets across the country for a free charge.
