When buying a car battery, suppliers often give the option of lower of higher power battery (e.g. 60Ah or 74Ah). The higher power should make it easy to start. What is the disadvantage? Does it take longer to fully charge it?

Higher CCA and Ah are better and usually carry a longer guarantee like 5 years .

Ah means capacity, CCA starting amps. Larger Ah usually means larger size. You can put as large as fits on battery rack.

It’s battery capacity. Not power. The amount of time a battery can sustain a particular load.

Try a 480V battery and see what happens ;)
