A larger battery creates a situation where electrical current can fluctuate. Without knowing the make model and year of the vehicle we can have no idea how your system works. 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.

Electronic measurements at the batterys terminals cannot accomplish this. In order to determine how much amperage a component is going to draw you can divide its wattage by the voltage of the system. A three-stage or smart charger is recommended for the best results.

The battery was already a couple years old so I went to the local auto parts shop purchased and installed a new battery. Thats the quick and easy answer but there are a few things you want to. In general a battery with too much cranking amps can be dangerous.

However the chance of damage is minimal. A standard alternator that charges the car battery during starting and the voltage range while running the car varies from 125 to 135 volts. While not stalled cranking a starter motor too long under such a load as a.

Anything higher than 147V indicates overcharging in the battery. Larger than the original CCA is overkill. The power and longevity of a battery is noted by its Amp Hour Ah rating.

The amps in the car battery should always remain close to 0000 to prevent it from damaging. There is no side effect at all even yr alternator will not be subjected to working overtime. Discussion Starter 1 Jan 11 2010.

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.

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. Its the tried and true method for well over 100 years.

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 Units The Factors.

Its my weekend fun car now The new battery has 875CA and 700CCA. So basic 50-watt headlamps are only going to pull maybe 4A 50W. Over-voltage will generate and vent gas and so dry out and damage the battery.

You may need to use jumper cables to get it started. The extra amphr capacity will act as reserve. Measuring the specific gravity of the fluid in each cell is the only way to know the state of charge of each cell.

Ive recently started having a bit of trouble with my car. Basically this denotes how long a battery will put out an amp of power if it isnt recharged.
