Hello, I use my 2007 Crossfire during good weather months in New York, and occasionally start it during winter. I have had persistent dead battery issues, which I don't mind except for one thing---it takes quite some time to get the car reset to pass NYS emissions inspection. I just installed a new battery so in an attempt to avoid all of this, I started to explore hooking up the battery to a battery charger (https://www.batterytender.com/battery-chargers). Does anyone have experience with this? I'm wondering if (1) they work and keep the battery charged for months, (2) is this a good brand, and (3) is there something else you would recommend?

Thanks in advance for your assistance.
