Tray and support cracking has been reported with heavy batteries and off road use, something to consider. Selecting a battery size 27F vs Group 31. The NorthStar 27F is 20lbs over stock for a 2nd Gen while offering Charging Voltage AGM batteries require a higher charge voltage than lead acid.
The voltage, when the engine is running, should be in the range of 13.5-14.7 volts. When your car is running the cars alternator is charging the battery, this is why you should see a higher voltage. If you’re readings are significantly higher or lower than these then it would indicate a fault with the battery and/or the alternator.
Consider an electric car with ten (12 volt, 75 Ah theoretical capacity, 1.1 Peukert) batteries and a 20 hp electric motor that draws 155 amps at 5000 rpm at 120 volts. As the ten batteries are in series, the current draw is not distributed among the batteries: each battery must provide the full 155 amps to feed the motor.
The internal chemistry of the battery will also affect the amp rating. Most car batteries have a capacity between 550 and 1000 amperes. Matters are further complicated by the fact that you’ll see two-ampere ratings on most batteries: the crank amps (CA) and cold cranking amps (CCA). Usually, the CA rating will be higher than the CCA rating.
I have a 95 isuzu trooper type s a/t recently my batter went bad and was since replace. however it drained quick and would not hold charge. i replaced the alternator and my lights are still dim and only running at about 11 to 12 volts while idle and driving. we tested the alternator but it is fine at 15 amps. anyone have any ideas what is causing this? please help
With your battery still being new (car batteries have a lifespan of approximately six years), a jumpstart should be all you need to get going. Once you have determined that the current drain you're reading is safe, gradually reduce the meter's scale to the appropriate low range, probably 2 amps or 200 mA.
Cold cranking amps are the discharge load a fully charged battery can deliver for 30 seconds while maintaining a voltage higher than 7.2 volts at 0 degrees Fahrenheit. In cold climates, the higher a battery's cold cranking amps, the more easily an engine will start. In hot climates cold cranking amps are not an issue with starting a vehicle.
Connected batteries should have the same voltage and amp rating. RV batteries in parallel. A parallel RV battery bank increases the current but allows the voltage to stay the same. If you join two 6-volt RV batteries in parallel, you will get 6 volts, but the amps will now be increased.
Can a car battery possess amperes without showing the presence of voltage? –no, not much likely is it the case. But, can a car battery possess a suitable amount of voltage but with a poor showing of amperes present at an hourly rate? – yes, and the battery usually runs with shallow energy or fails to start up or deep cycle as a result of this.
If the battery has a maximum discharge rate of 10C, the maximum current is 20 amps. A typical alkaline or NiMH battery in the standard "AA" size has about 2000 to 3000 mAh (or 2 to 3 Ah). With a cell voltage of 1.2 V to 1.5V, this corresponds to 2 to 4 Wh per cell.
