It might also result in trouble while starting your car. A much higher Ah rating can put a huge amount of load on the alternator, so to get the best replacement car battery, choosing one with the right Ah rating is vital. If the battery is not of the right size, it will not fit properly in the battery tray of your car.
What happens if you install a bigger battery on a car?
The battery capacity won’t impact it at all except taking longer to charge. The vast majority of the alternators output is directed to running the vehicle and any accessories. The charge rate on any battery is well below what the battery is rated for.
Will putting a different size battery hurt your car?
If you use the wrong size battery, this could cause changes in the flow of electrical currents, resulting in power surges that can damage the onboard computers or other components.
Does it matter what size battery I put in my car?
Manufacturers precisely match their batteries to the vehicle’s power requirements. An oversized battery could cause your alternator to overheat and wear out sooner. Using an undersized battery in your car could lead to starting problems.

Can I use a battery with higher cranking amps?
A car battery must only fit the minimum CCA requirements to work well. This means that if you have met or exceeded the CCA of the original battery, there is nothing to worry about. Many would agree that the higher the CCA rating, the better the battery is for your car.
Can the wrong battery damage the alternator?
Manufacturers precisely match their alternators and batteries to the vehicle’s power requirements. A mismatched battery/alternator combo could cause your alternator to overheat and shorten its life.
How do I know what battery to buy for my car?

How do I figure out what battery I need?
You can calculate the battery size for inverters using the formula B = P × t / Vdc, where B is the battery capacity in ampere-hour, P is the inverter’s power rating, t is the duration of power supply in hours, and Vdc is the DC voltage of the inverter.
Can I use a lower CCA battery?
Getting lower CCA than your original battery means that in cold temperatures your car may not start, but if you live in a mild climate you’ll probably get away with it. Ah is more of a measure of how long it can deliver power for, than how much. The CCA is the measure of how much power can be delivered.

What happens if I use a higher Ah battery?
Using a battery with a higher Ah will improve the device’s running time on a single charge. This feature is important if the power frequently goes out or is out for long periods of time. However, the higher the Ah is on a battery the bigger (physically) it will be.
What happens if amps are too high?
A higher voltage than a device is designed for will most likely blow up some components, but amperage is derived from how much current is actually drawn, based on the device’s resistance, so having “too much” is not a problem and will do no harm.
Does higher amp damage battery?
Yes, it does! Each and every battery types are made up of special chemicals and they charges and discharges in a given time period. Every one of them has their own current rating at which they can be charged and above which if you go it will harm the battery!
What are the signs of a weak battery?

What does 60Ah mean on a car battery?
The Ampere-Hour Capacity is the amount of electricity that a battery will deliver during 20 hours before the voltage falls to 10.50V. For example, a 60Ah battery will deliver a current of 3A for 20 hours. Recommended Charge Rate (Amps)
How many amps is a car battery?
