car battery amps too high

This does not necessarily mean a battery will last only one hour because it. This is particularly important in the event the alternator fails.

Acdelco 94ragm Car Battery Battery Rv Battery

Warranty cranking amps reserve capacity RC and cold cranking.

. Most of the new battery are dry charge 100 Charge once installed it can be used instantly. 1990 300ZX NA 22 that I purchased in Aug. Measure the voltage from the alternator.

I have fitted a much larger 12v battery to a car. A larger battery creates a situation where electrical current can fluctuate. This is because repeatedly fast-charging a car battery may lead to overcharging and will severely reduce its performance.

More than what is. Big_Dawg February 16 2009 345am 6. The colder it is outside and the harder your cars starter has to work the more important high cold cranking amps become.

Meaning the plates are fully charged if the voltage goes too high. Thats the quick and easy answer but there are a few things you want to. Fifteen 15 volts charge denotes the fault of the voltage regulator of the charging system.

A fully charged car battery voltage for a vehicle that isnt running should fall between 124 volts and 126 volts. Generally a car battery pulls approximately 400 amps for small vehicles to start and more than 1000 amps for the large ones. Basically this denotes how long a battery will put out an amp of power if it isnt recharged.

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. A regulated charger will hold the voltage to 135 to 138 volts once the. Measuring the specific gravity of the fluid in each cell is the only way to know the state of charge of each cell.

Its the tried and true method for well over 100 years. Each battery is complete with 6 separate cells that each contains 21 volts for a total of 126 volts. Starting the car is by far the highest load on the battery.

Charging amps in this range will allow the battery to be completely charged overnight and will not be at risk of overcharging. 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. The Units The Factors.

Yr battery shop mech and yourself have make a right and good choice. Thanks to all for your responses. 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.

It may seem counterintuitive but higher. If your car battery is 12-volts it will begin the charging process at 138 volts which is the pressure behind the amps. The extra amphr capacity will act as reserve.

Charging a car battery at 4 to 75 amps is the safest and most efficient. There is no side effect at all even yr alternator will not be subjected to working overtime. Most car batteries are rated in Cold Cranking Amps CCA to determine how well they will turn the starter when it is cold out.

The amps in the car battery should always remain close to 0000 to prevent it from damaging. Fifteen 15 volts is very high for an alternator. Electronic measurements at the batterys terminals cannot accomplish this.

How many Amps to Charge a Car Battery. Except in BMWs under load and wont wear it down any more. 10 amp chargers are.

Check for a faulty regulator if you find that the voltage regulator works like an electrical current that runs volts through the battery. It is a car battery that is not running a car but is loose. Radios amplifiers and other electronics could receive damage as a result.

Ah amp-hours is the rating for for the battery to provide 1A for however many hours. Also the device does not do what I want at 6 a but will do. The power and longevity of a battery is noted by its Amp Hour Ah rating.

The more cranking amps a battery has the higher its CCA cold cranking amps. The battery stores power accessories draw power the alternator feeds power to the battery. If the voltage regulator goes bad it can overcharge your car battery.

This number indicates how long the battery can maintain a 25-amperage draw before dropping below an unusable 105 volts. However the chance of damage is minimal. The battery keeps a steady supply of power.

Ok it is a 12V 6a device see it as a sort of a heater that I want to only draw around 1a or it will suck the battery dry in no time. If your car battery voltage is discharged or has less than 124 volts the power decreases dramatically. That is why the car manufacturers provide bigger amps in the car battery than it needs to start.

Slow charging using 10 amp chargers or less is generally accepted to be better. The extra reserve in the battery wont be used except under adverse conditions when youll be glad you have it. Summer heat is tougher on car batteries than winters chill.

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. A three-stage or smart charger is recommended for the best results.

The higher this number is the longer the battery will crank the engine in cold weather before it dies. Its my weekend fun car now The new battery has 875CA and 700CCA. When choosing a new battery for your vehicle consider all of these factors.

A standard alternator that charges the car battery during starting and the voltage range while running the car varies from 125 to 135 volts. 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. By Jeff S.

In a few seconds youll know the condition of the battery. For example if a battery is rated as say 50Ah it will be able to provide 50 amps for 1 hour. Is 15 volts too high for alternator.
