Actually when the car is running, the battery takes very little load.
The alternator is handling all of the load and putting current into the battery.

SO normal operation of a good running car should be fine for one of these batteries.
However, if you sit for long with the accessories on and the engine not running, OR if your alternator dies, then you are putting a HUGE burden on the battery.

That is why the OEM battery is so big in the first place.
