Is higher amp car battery better?
Is higher amp car battery better? The more capacity (Ah) a battery has, the more electricity it can provide. That is, the same battery could give 4.75A for 20 hours (4.75A x 20 hours = 95Ah c20), 9A for 10 hours (90Ah c10) or 17A for 5 hours. Should I charge my car battery at 2 amps or 6 amps? For faster charging, get a higher amperage charger. If you need a charge in a hurry, it makes sense to increase the amperage. Going above 12 amps can be risky if done for an extended time. Charging for too long...
