Battery ODYSSEY or OEM Mercedes

My go to now is odyssey, though they are fairly pricy. If i dont have a choice, like when my battery literally [exploded](https://www.reddit.com/r/Justrolledintotheshop/comments/pqcbcm/i_sounded_like_a_shotgun/], i get optima.

I swear by odyssey batteries in particular the pc1500st

I've installed the Odyssey Extreme battery in my Outback. These are AGM with 99% pure lead, not the alloy. Best battery I've come across.

When you say, \u201ctwo new batteries\u201d are you speaking of the big ones? There is a small one that operate your convenience/comfort items. It looks like a small garage door battery.

With winter coming, I bought an odyssey extreme battery for my 2017. I’m not going to risk it.

I have one of these and its been perfect for 5 years with a 700watt sound system on a v8 truck.

I have the Odyssey Yellowtop

I'd like to say Ive had good luck with the Odyssey but it has maybe seen 100 kms in the 7 years since I put it in so no comment on the quality of the battery.

I've dealt with this issue on both of my newer AMG vehicles. My older ones never had this problem. From my understanding, this is caused by the new mbux system being a bit of a power hog. I eventually had to invest in a trickle charger, and I have to charge both of my AMGs 3-4 times per year. It gets worse as your battery gets toward the end of its lifespan.

I installed the old battery after recharging it and it has been working great until now. The new battery was faulty and I ended up returning it for a refund.
