ODYSSEY Performance 94R-850 Automotive Battery

I had purchased Oddessey Batteries in the past but I bought the Extreme ones which are an excellent product still have one in use, the performance one is horrible, didn’t last and of course amazon. I had purchased it with the hope it was going to be like the Extreme edition for quality since I am a Paramedic and need to get to work no matter what and can not be stranded. Sadly I was mistaken and I think Amazon knew this for the fact they didn’t allow returns after 3 months on a battery when most batteries have a 4 year warranty. Thank you Amazon for my disappointment in your quality control of product sold by you.

This h7 AGM Odyssey battery is the best starter battery you can buy. Fit fine in my jeep gladiator. Even if you have the smaller factory non tow package this h7 battery will fit fine and if doing the aux delete this is the battery you need.

Also found out it’s made in America with brand new lead. Not the recycled lead the others use in mexico.

I forgot about this, and needed to update. MB dealer apparently was right. It seemed to start charging back up, and even appeared to be charged, until it didn’t. There was/is something wrong with it, something I’ve never experienced but while it showed to have charged up, although a little rough, it didn’t have power and acts as if it’s internally shorted, to the point I wasn’t comfortable putting any charger back on it. $250 out the window. FYI, I’m about to replace a pair of Odyssey Extremes in my truck that are about 6 years old. They’re weaker, and worse with temps in the 20’s and it sitting for several days, to the extent, in this winter storm after not being ran in 4 days, they can’t start my 6.0 PSD. But they’re taking a charge as normal. 6 years in sub-optimal conditions for any battery, but those were Extremes and bought from a truck aftermarket retailer. For this battery listed here, I bumped my rating down to 2 stars just because it did work, but not without strange issues, for several months. With the nearly 50% increase in price at this time (2-1-’23), I’d run from it.

It’s been several months, but the same issues started up with this battery. MB dealer wanted to replace with an OEM so we swapped it. Luckily I kept the original. They said the Odyssey tested bad. ??? I put it on a charger/conditioner and it took about 48 hours to act right. It did seem to eventually charge back like it should be. I’ll be checking it again to see if it indeed seems healthy again.

The 2 Odyssey Extremes I have on my truck never take more than 30 minutes or so to show 100% back to normal, as if they’re still brand new. This one may just be a dud, or there was an issue with the car but who knows. Looks like my daughter has a $250 extra battery or anchor. FYI, because it had been several months, I didn’t contact the seller. I’d have a hard time expecting them to take it back at that point especially not being confident that the battery is the issue.

My daughter MB started getting finicky because a slight voltage drop in the OEM battery. Starting just fine, but when cold especially, would tell her the voltage was low and to stop and let the car idle. It also would not go into Eco mode when stopping (shuts the engine off but keeps everything else powered while sitting at a red light for example)

Putting a god charger on it showed it was still healthy but the car wasn’t happy with whatever little drop it had. I switched my truck (diesel) over to Odyessy Extremes 2 years ago and will never run a different battery. It’s the power hungry Ford 6.0 PSD that eats batteries. The Odyssey’s keep the truck and all the control modules that suck batteries dry, very happy. So it made sense that I’d talk my daughter into an Odyssey for hers. As luck would have it, I found the original OEM spec battery by Odyssey available but very limited so when it was available I ordered one. MB has changed the battery spec’d for the car but it’s not the same amps, or size.

I popped this one in her car and it’s happy as can be. She thought it was expensive, until I showed her what an MB dealer would charge to replace it with another US made AGM MB OEM battery (smaller now) vs. Dad’s free labor and a much better quality higher power battery.

So, I read all the great reviews and hype. I purchased this battery for my 2014 Ram 1500 which is driven under normal conditions. It died suddenly after nearly 8 months. Tested with a multimeter and at first thought maybe it was time to replace the alternator since I just dropped over $300 on this fancy battery that’s supposed to be one of the longest-lasting on the market. 😀 😀 Nope. Completely dead, won’t hold a charge. I dropped my old battery back in and the truck started right up. Odyssey won’t honor warranty because Amazon is not an authorized reseller and amazon warranty support hasn’t responded. VERY, VERY disappointed with both entities! DONT WASTE YOUR MONEY.
UPDATE: After 3 emails to Amazon warranty service and only receiving a standard boiler plate message about not including all of the required information I was extremely frustrated. From the very beginning I had included all the requested info, but it seems like they were trying to kill time and get me to give up. I contacted customer service again and after explaining my very frustrating quest to get my money back the very attentive rep smoothed my ruffled feathers and issued a complete refund to my credit card. I am very impressed with the end result and overjoyed at this outcome. I still won’t ever purchase an Odyssey product ever again. My review of their product and service remains rigid.
