Battery OEM Mazda or ODYSSEY

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

Going with Odyssey MK7.5. The one in my Raptor is awesome 3 years old and tests like it was new. Its not lighter but its a great battery. Try Braille batteries.

I've been using an Odyssey 925 in the Miata with no issues. It gets driven mostly on the weekends and a few times during the week but stays on a B&D 2 amp tender when not driven. I've had this setup for about 6 months so far and it works great for my particular situation with a 3rd car.

The Odyssey PC680 is probably the best battery out there, if you can make it fit. I'd stay away from lithiums, you buy those when you are looking to save weight. For reliable low temperature operation, stick with a lead acid thats had decades of development.

I used straps like the first link when I had an Odyssey battery a few years back. Eventually went back to an OEM one but the straps were an easy solution

the stock battery only lasted 3 years. My VW prior lasted 7 on the OEM battery.

Battery died less than 12000 miles. Apparently Mazda is using cheap batteries, as this seems to be a common issue. But I still see others complain about the same thing.

first issue I had was the battery at around 2000 miles, it was replaced under warranty.

Odyssey and wasn't a fan died quick
