A 12cell ballistic will be plenty. But if you're getting some kind of parasitic drain, you'll probably need the dealer to address that. So just try the new battery out. If it stays charged, all is good, if it dies down also, you have something sucking the life out and you need to have the dealer find the issue.

Glad it worked out.

I recommend a CTEK 4.3 trickle charger. They can be had for $55-65 and will greatly extend battery life for people like yourself that do not drive them every day. You can also use the same charger on your cars.

I use a CTEK on my Ferrari, Porsche, and S1000RR. The CTEK also "might" be able to save your battery, but I would start over fresh.

You can find the CTEK on Amazon and a myriad of other retailers.
