How cold does it get in that underground parking? If it stays reasonable, then I wouldn't even worry about it. Put a voltmeter on it occasionally, if the voltage drops fast, pull the battery and take it inside. I'm typically anti-tender. I've observed more batteries fail prematurely that have owners using tenders than not. That's my observation and personal experience, no scientific backing, and I'm sure the pro-tender crowd will make their case. Everyone is free to do what they want. I think a big problem with using tenders is that a lot of people use one with too much output amperage, and I think that hurts these small batteries. For MC batteries, I like to recommend the Battery Tender Jr. or similar with only a 750mA output. I own this unit, but I use it for charging and not tending. Good luck.
