At 3.5 amps it's ideal for charging and maintaining powersport batteries, but at 3.5 amps, a discharged automotive battery will likely take well over a day to charge. A general "good" amp rating for automotive use is closer to 12 amps, at the very least north of 6 amps. Check out the Clore PL2320. Good unit at a good price, a bit more professional-oriented with the power supply mode, but that's just an assurance that the innards are on point.

As for how often, I throw a charger on my car (which doesn't have any ignition off drawing accessories) typically twice a year just because I drive really short cycles. Your circumstances and usage may vary.
