So my 2004 OEM 720 CCA battery had finally died (wow it had lived a good life!), and I'm in need of a new battery. Considering I'll be upgrading my sound system in the near future, I was wanting to get a powerful battery that could withstand the subwoofer voltage drops. I've been looking at the Deka Intimidator PA49. Has anyone had any experience with these? Or would you have any other recommendations?

PS: I think the low/dead battery is the root cause for me not being able to wind/unwind the windows via key fob, along with the issues I've had with the welcome lights not switching on. Hopefully a battery replacement will fix all these problems!

I've been told that the OEM battery from the stealership is the best way to go. Expensive but supposedly they're the only ones that work well with these cars. Lemme know if you find different. My battery just died today too.

Just came back from installing a Deka Intimidator PA49 (apparently it just came out to suit the E60 5 series). It fits in beautifully, and its 850 CCA's! So far I'm a happy chap

I still can't roll up/down my windows via keyfob though =/
