Bigger is better for car battery?

[Chris_ck]

Fact or Myth? A bigger car battery is better for the car than your normal car battery? I read about it somewhere before but forgot about it. Of course your engine compartment need to have space for the bigger battery

[Koolaba]

In your context, does bigger battery mean higher amperage?

[Vtim]

If your car is loaded with ICE, then it will be better to change the stock battery to one with higher ampere/hour

Just wanna ask those batt experts out there:

 

Let's say I have two batteries, one is rated at 60AH 280A while the other is rated at 63AH 480A.

 

So which is better and why? (Besides the higher ratings...what does it mean?)

[Chris_ck]

Yup i mean higher amp and i gather the physical size of the battery will be bigger also right?

[Madarmour]

IMO, a bit of extra amp wouldn't hurt. Just don't get one that's lower amperage than stock. Generally, most ppl start to ADD electronics on their car like ICE, various meters, extra lights, etc so additional power is needed.

 

For me, my recommended amperage is 66 but I use a 72 amp battery. Of course, you've gotta take the size of the battery into consideration. No point getting a big, big one if it doesn't fit!

[Koolaba]

Yes that's right

[Turbobrick]

Firstly your stock alternator must be able to charge up a bigger battery compared to stock.

 

Secondly, a slight upgrade (like one rating up) is fine, the car may start easier and can possibly last longer in even of headlight left on when the engine is off. This does not mean we all go out and start buying marine batteries

 

Too much is not always better

Yup i agree. Too much of a good thing is not always good. As the wise always practise moderation
