Help me select a new battery

The battery in my M3 is original and it starts the car with zero issues. I drive the car once a week max, but sometimes its two or three weeks between drives. I recently saw the battery discharge alert on my display, so I guess at 10 years its time to replace this one.

I know higher CCA is better, but I see the batteries now have aH ratings. Does that refer to charging capability or supply capability? The stock battery is up in the 90aH range but I see people putting in 40aH and saying "no prob".

Before anyone says "use the search" I've been doing a lot of reading here over the past hour and saw references to Bosch, Voltphreaks and Antigravity and I'm sure there's many others. I took a look at what EAS offered and my eyes glazed over after a couple of minutes. Many options, 7 to be exact, and I have no idea what I'm supposed to get.

I'm looking for:

A battery that hooks up with no adapters needed and uses all the BMW hold down brackets. Lightweight is a plus, obviously, even though this car will never be on a track. A little bit of a diet never hurts. I just want the thing to behave like stock and integrate well into the electrical system. Something that can stand being parked for a few weeks as well as the stock 10 year old battery has, because I don't use a battery tender. Cheaper would be better, as I'm about to drop a bag of money on tires, alignment, motor mounts, control arms, a lift, an addition to my house, etc.

Antigravity is a good value for an all around product.

I have voltphreaks for maximum lightness.

Just get what's listed on the eas website. Sign up for their email list. They have good holiday sales.

Pick the one with the largest capacity if you want to let it sit for a few weeks at a time.
