car battery amps too high

Fifteen 15 volts is very high for an alternator. Check for a faulty regulator if you find that the voltage regulator works like an electrical current that runs volts through the battery.

Your car might not have to have more than 150 amps to begin using the power supply.

. The Units The Factors. Measure the voltage from the alternator. Thats the quick and easy answer but there are a few things you want to.

Its my weekend fun car now The new battery has 875CA and 700CCA. The amps in the car battery should always remain close to 0000 to prevent it from damaging. This is true but a starter motor in a car is turning an engine that has compression in it.

Radios amplifiers and other electronics could receive damage as a result. Yr battery shop mech and yourself have make a right and good choice. I was able to start the truck fine in -16 degree weather.

The extra amphr capacity will act as reserve. A really large battery will place a greater strain on the car if it goes dead and. Meaning the plates are fully charged if the voltage goes too high.

Its the tried and true method for well over 100 years. This simulates the summer. That presents a significant load to the motor.

Is 15 volts too high for alternator. Charging a car battery at 4 to 75 amps is the safest and most efficient. Larger than the original CCA is overkill.

If the car battery voltage shows a lot less than 137 volts while driving you should check your car alternator. If your car battery is 12-volts it will begin the charging process at 138 volts which is the pressure behind the amps. How Many Amps Is Too Low For A Car Battery.

A fully charged car battery voltage for a vehicle that isnt running should fall between 124 volts and 126 volts. Again the voltage should show a measurement between 128V and 147V. As for car batteries it is a rule of thumb not to fast charge them using anything that exceeds 20 amps.

Most of the new battery are dry charge 100 Charge once installed it can be used instantly. The extra reserve in the battery wont be used except under adverse conditions when youll be glad you have it. So having a high Ah on the battery is important physically.

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. The last two days I noticed my battery gauge reading high now it is a little more that half way between the middle and high mark on the gauge. The battery was already a couple years old so I went to the local auto parts shop purchased and installed a new battery.

A larger battery creates a situation where electrical current can fluctuate. But while you are driving your car the battery voltage should be higher than that. That is why the car manufacturers provide bigger amps in the car battery than it needs to start.

This is because repeatedly fast-charging a car battery may lead to overcharging and will severely reduce its performance. If the voltage regulator goes bad it can overcharge your car battery. Only show this user.

Big_Dawg February 16 2009 345am 6. 1990 300ZX NA 22 that I purchased in Aug. A three-stage or smart charger is recommended for the best results.

The OEM battery has no trouble cranking over the engine on those rare days when the weather is extreemely cold. When you drive your car the battery voltage should be between 137 to 147 volts. A couple weeks ago I went on vacation and when I returned my car battery was as dead as could be.

Slow charging using 10 amp chargers or less is generally accepted to be better. More than what is. Stuck in an open state.

The amplifier stays on now but theres another problem. A fully charged car battery voltage should be 126 volts or above. A regulated charger will hold the voltage to 135 to 138 volts once the.

10 amp chargers are. Only under that stalled fault condition can continued use of the starter with a high capacitance battery damage a starter motor. Charging amps in this range will allow the battery to be completely charged overnight and will not be at risk of overcharging.

If your car battery voltage is discharged or has less than 124 volts the power decreases dramatically. There is no side effect at all even yr alternator will not be subjected to working overtime. How many Amps to Charge a Car Battery.

However before I start pulling fuses and testing the amps I thought Id verify whether 8 amps. I put in a resistor between the battery positive to my amplifier power line and it reduced the voltage by 1v so about 15v max now. Fifteen 15 volts charge denotes the fault of the voltage regulator of the charging system.

A standard alternator that charges the car battery during starting and the voltage range while running the car varies from 125 to 135 volts. In a few seconds youll know the condition of the battery. 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.

However the chance of damage is minimal. Thanks to all for your responses. While not stalled cranking a starter motor too long under such a load as a.

Each battery is complete with 6 separate cells that each contains 21 volts for a total of 126 volts. The speaker starts stuttering when the volume is up and it has to play sustained low notes so I think the resistor isnt allowing enough amps through. - The average car battery cranks out about 550 CCA.

I also got a check gauges light one time when I started the truck. Battery life is measured by repeatedly discharging and recharging at a test temperature above 160 F for 15 weeks or until performance drops to unacceptable levels. Measuring the specific gravity of the fluid in each cell is the only way to know the state of charge of each cell.

In general a battery with too much cranking amps can be dangerous. Depending on the type of battery you have your batterys power should start between 400 and 600 amps. 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.

How Many Amps Should A Car Battery Be. Discussion Starter 1 Jan 11 2010. 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.

Generally a car battery pulls approximately 400 amps for small vehicles to start and more than 1000 amps for the large ones. Electronic measurements at the batterys terminals cannot accomplish this.
