The current draw will remain the same. Because of this, a larger battery will not deplete faster than it’s smaller counterpart. So, if your vehicle has an average current draw of 75A, it will deplete the battery the same amount. Therefore, you will have the same amount of current to be replaced with both sizes.
Is a bigger car battery better?
Most vehicles have limited space for batteries, so in many cases a larger size, from a physical standpoint, may not work. Battery physical size does not mean that the battery has more power or longevity. …
Is it bad to have a bigger battery in your car?
As several people have stated, no, a larger battery will not harm your alternator (or other electrical components), provided that it is putting out the correct voltage. … When you use a larger battery, your car’s electrical systems don’t automatically start pulling more current simply because it’s available.
Do higher battery car batteries last longer?
The CCA rating of a battery will gradually reduce with time, so batteries with higher CCA ratings do have the potential to last longer.
Can a car battery have too many CCA?
In general, one can always exceed the CCA spec. You probably do it on a warm day, with a charged battery. Having more potential current available will not hurt the car’s electrical system.
Is higher cranking amps better?
In general, for both CCA and RC, the higher the number the better. However, if you live in a cold climate, the CCA rating should be an important consideration in choosing a battery. Conversely, if you live in a high heat climate, you don’t need as much CCA.
Is it OK to have more cold cranking amps?
Well, that’s still very important, because cold, cranking amps tells you the ability of the battery to do work right now. And the higher the cold cranking amp rating of the battery, the better it is for your car.
Can a completely flat car battery be recharged?
If the battery is your only problem and the car is in otherwise good working order, it is quite possible to completely recharge a completely dead battery. Using the charger or a jump start or push start and then letting the engine idle with electrical items switched off.
Do car batteries go bad if not used?
Most car batteries which are in good condition will last at least two weeks without needing you to start the car and drive to recharge it, according to the AA. But if you don’t intend to drive your car for some time for whatever reason, you should still start it up once a week to recharge the 12V battery.
What is the difference between 24F and 35 battery?
Dimensions. With these two batteries, the difference in size is relatively minute. Group 24F batteries measure 10.3 x 6.8 x 8.9, whereas the Group 35 batteries measure 9.1 x 6.9 x 8.9. Immediately you can see that the 24F battery is that bit longer than the Group 35 battery.
How do I know what size battery to buy for my car?
Look directly on the battery you’re replacing. Particularly if it’s original equipment, you can usually find the group size printed on the top or side labeling. You’ll also find other information here, like cold-cranking amps and reserve charge, that can be helpful as you shop for your replacement.
How many cold cranking amps do I need?
The standard recommendation is a battery with at least one Cold Cranking Amp (CCA) for every cubic inch of engine displacement (two for diesels). CCA rating is an indication of a battery’s ability to deliver a sustained amp output at a specified temperature.
