Why does your car turn over slowly and barely starts when the battery is at 12.6 volts?
first of all if you have a good battery and im not saying you do but it could be fuel or air intake, your starter, or loss of compression..
but to test a battery you have to check it before you start your car then get someone to crank it and test it again because all battery will keep a surface charge but they loose that once a load is applied
What else can I help you with?
How many volts should your jeep battery be?
A fully charged 12 volt automobile battery will read 12.6 volts with the engine not running and 13.5 to 15.5 volts with the engine running. It will read 12.4 volts with a 75% charge, 12.2 volts with a 50% charge and 12.0 volts indicates a 25% charge.
Can a jump start charge a dead battery?

New battery but again car wont start how do you tell if its battery cables or alternator?
Alternator can be discounted for starting problem; it charges the battery when the engine is running it has nothing to do with starting the car. If the engine is not turning over (cranking) when you try to start it, either the igniton switch, wiring or starter motor are at fault. Also check the thick cable from battery negative/body to the engine block. NOTE if the car is automatic the park/neutral switch could be faulty. If the car is alarmed it could be an immobilizer fault. Difficult to know from your question but if engine starts with charged battery, check WITH ENGINE RUNNING for 14 volts approx across battery terminals. If volts less than 12, swap out the alternator
91 dodge stealth having trouble starting it will push start and alternator builds power until headlights work but if you stop the car it wont start again any ideas?
You need a new battery or it has a battery cable connection problem. The battery needs a full charge too - like driving around for an hour to charge it back up. A voltmeter is useful to read battery voltage when cranking. 12.6 volts =full charge. When cranking it may drop to 10 volts. If the starter won't turn over use the voltmeter to check for the 12 volts on the battery and then starter battery cable connection point.
Why do your car starts slow?

What causes your voltage needle to rise slowly?
It is normal for the gauge to increase slowly when you first start the vehicle. This is because the voltage regulator is compensating for the power that has been drained from the battery during starting the vehicle. The voltage should stop around 15 volts though, if it continues above 16 volts you could have a bad regulator. Voltage above 16 volts can damage your battery and other electrical equipment in your vehicle.
