Note that [[opinion:frater_secessus:charging_faster|bigger is not always better]]; different battery chemistries and capacities accept current at different rates. Buying more charging capacity than the battery wants((or should have for its own good, see Li below)) is a waste of money. Buying more charging capacity than your alternator can deliver constantly can overheat/damage the alternator. | Note that [[opinion:frater_secessus:charging_faster|bigger is not always better]]; different battery chemistries and capacities accept current at different rates.
