car battery amps too high
I modified the clamp and battery tray to make it fit securely its almost twice the size of the original and has a much higher CCA rating. The Units The Factors.

There is no side effect at all even yr alternator will not be subjected to working overtime.
. Thanks to all for your responses. If a battery is. No one can figure it out.
How many Amps to Charge a Car Battery. Fix your alternatorregulator first. Basically this denotes how long a battery will last if it isnt recharged.
For example if a battery is rated as say 8Ah it will be able to provide 4 amps for 2 hours. I had the same problem. That is why the car manufacturers provide bigger amps in the car battery than it needs to start.
For city driving its good to have a bigger capacity battery. Ah amp-hours is the rating for for the battery to provide 1A for however many hours. Over-voltage will generate and vent gas and so dry out and damage the battery.
In order to determine how much amperage a component is going to draw you can divide its wattage by the voltage of the system. Each battery is complete with 6 separate cells that each contains 21 volts for a total of 126 volts. Do not use series.
A standard alternator that charges the car battery during starting and the voltage range while running the car varies from 125 to 135 volts. If you want to know how many amps a battery delivers multiply its capacity in amp-hours by 013. That means it can deliver enough current to start a car or run a light bulb.
Generally a car battery pulls approximately 400 amps for small vehicles to start and more than 1000 amps for the large ones. You asked and we delivered. It refers to how long a vehicle can produce electrical currents before it gives in to exhaustion.
AMPReviews now provides the option to upgrade to VIP access via paid subscription as an alternative to writing your own reviews. The average car battery uses 12 volts. Radios amplifiers and other electronics could receive damage as a result.
A fully charged car battery voltage for a vehicle that isnt running should fall between 124 volts and 126 volts. If your car battery is 12-volts it will begin the charging process at 138 volts which is the pressure behind the amps. If the car battery voltage shows a lot less than 137 volts while driving you should check your car alternator.
A fully charged car battery voltage should be 126 volts or above. Meaning the plates are fully charged if the voltage goes too high. Sometimes it is right where it should be - at 14 v - but often it overcharges with a 155 reading.
When you drive your car the battery voltage should be between 137 to 147 volts. Another unit for measuring car batteries is the Ah which means amp hours. Without knowing the make model and year of the vehicle we can have no idea how your system works.
However the chance of damage is minimal. Its the tried and true method for well over 100 years. Fifteen 15 volts is very high for an alternator.
This happens in newer vehicles with alternators that need signals from the vehicles electronic control unit. If your car battery voltage is discharged or has less than 124 volts the power decreases dramatically. I firmly believe that it is an onboard computer.
Additionally an incorrect replacement battery in the vehicle can cause an overcharging condition. Charging a car battery at 4 to 75 amps is the safest and most efficient. - The average car battery cranks out about 550 CCA.
The extra amphr capacity will act as reserve. The shop replaced the alternator and the battery but the problem persisted. Electronic measurements at the batterys terminals cannot accomplish this.
On the other hand amperage is the volume of electricity the car can generate usually an average of 600 amps. Except in BMWs under load and wont wear it down any more. This surge disrupts the wiring in the alternator causing an overcharging condition.
Most of the new battery are dry charge 100 Charge once installed it can be used instantly. Today I let my car battery charger charge a car battery over about 8 hours and probed the voltage to be about 15V with still 2 amps being pumped through by the charger though the current was slowly. Fifteen 15 volts charge denotes the fault of the voltage regulator of the charging system.
Is 15 volts too high for alternator. In a few seconds youll know the condition of the battery. The amps in the car battery should always remain close to 0000 to prevent it from damaging.
One of the first things that may be impacted is the regulator on the alternator -- which would allow the direct current to change to alternating current. The extra reserve in the battery wont be used except under adverse conditions when youll be glad you have it. Measuring the specific gravity of the fluid in each cell is the only way to know the state of charge of each cell.
But while you are driving your car the battery voltage should be higher than that. Answer 1 of 20. A car battery provides 12 volts at around 13 amps.
Charging amps in this range will allow the battery to be completely charged overnight and will not be at risk of overcharging. Big_Dawg February 16 2009 345am 6. A regulated charger will hold the voltage to 135 to 138 volts once the.
More than what is. In general a battery with too much cranking amps can be dangerous. For example a 24V battery rated at 15 amp hours would give you 24 amps per hour.
A larger battery creates a situation where electrical current can fluctuate. I have fitted a much larger 12v battery to a car. The amount of amps used is up to the owner but common amp chargers are 15 or 2 to top off or maintain or 4-6 amps to charge a battery from dead overnight.
August 9 2007. 1990 300ZX NA 22 that I purchased in Aug. That being said its not exactly easy to have an over-powered battery for your car because most batteries are designed optimally at the factory so they dont put out any more power than what is required by the vehicle.
So basic 50-watt headlamps are only going to pull maybe 4A 50W. The power and longevity of a battery is noted by its Amp Hour Ah rating. A three-stage or smart charger is recommended for the best results.
The alternator generates enough amperage to meet the needs of the combined electrical system at any given time and then each component draws its share. Its my weekend fun car now The new battery has 875CA and 700CCA. Thats the quick and easy answer but there are a few things you want to.
