H3 Battery: Anyone Use an Odyssey Battery?

Bigunit · Jan 25, 2012

Went by to see my friend Dwayne (the Monster garage guy) this morning and we got to talking about batteries to power a winch, lights, etc. He suggested either a dual-battery set-up or if I want to keep the OEM single-battery set-up in the T, that I should go with a dry-cell Odyssey battery. Not cheap, but he's been running the Odyssey for years & he swears by them. Has anyone had any experience with this battery in your H3? Any thoughts?

The Odyssey battery is an absorbent glass matt (AGM) starved electrolite battery. They won't leak acid even if cracked or perforated. The other advantage is they use nearly pure lead and zinc so the internal resistance is very low. This means you can charge and discharge them very fast. They can support much higher current draw, like a winch can demand. They can also go dead very fast so be careful.

They require slightly different charging voltages, so make sure your voltage regulator has an AGM battery charging profile.

No experience with using them in an H3 but I have used several Odyssey batteries before in car audio installs. The Stinger car audio line of batteries are relabeled Odyssey batteries also. Odyssey makes a great quality and reliable battery. I plan on using a single G31 battery over a dual battery with my winch.

I had just looked into these myself. I really could not find anything bad about them on any of the forums. I did read a ton of mixed reviews on the Yellow Tops though. I'm looking to do dual batteries and almost 100% I will end up putting these in. the JK owners seem to like them to date.

Will the odyssey battery fit in the OEM battery compartment?

Bigunit · Jan 25, 2012

cg,
Yes, according to Dwayne. If you can wait until he gets one in, I will let you know for sure. I'm sure I will be getting one as, I'm due for a new battery - I still have the OEM battery and I've had the T for 2 1/2 years now.

Yellow tops are very hit and miss from what I have seen. Some guys get a good battery and never had a problem then there are some who get the crappy ones...One buddy of mine has gone through 3 in a little over a year. The only reason he keeps getting new ones is because they are for free w/ the warranty, still a hassle but free...

Alright cool, i dont need a new battery yet, but if i can get one that works as well as duals, but still keep the oem look.

I have had 2 odyssey batts in my truck for several years. They are expensive but the best batteries I have ever owned.

Great Battery......... Can't fault it.

For the last 4 years I have had the OEM battery with and Odyssey in the OEM spot. I ditched the OEM box (but used a PC 680 MJ (metal jacket) to compensate for it.)

PC 680 is very small form factor starting battery (High CCA Racing Battery). In my configuration it stays fully charged and everything else runs off the main battery. If the main battery gets too low I hit the push button solenoid in the cab and it will start off the Oddysey.

Cheers,

I agree, Odyssey is the best, and depending on which one you choose, you can fit one in the stock casing mount, or just remove the casing and install the bigger one like I did, with dual posts, so you can have the additional connection spots for other components such as sound system, winch, exterior lighting, etc

Bigunit · Oct 3, 2014

I agree Renegade. I did the same thing. I have a group 34 Odyssey and power my winch off of the second set of terminals.

i run the same setup and love it.

I have the Diehard Platinum in my Alpha. From what I read it's also just a rebadged Odessey Battery. If u use a winch or do a lot of amp draw on a battery a deep cycle is the only way to go!! Standard batteries will work up to the point of either being drained down to far or to many up/down cycles.

Just had to trim the fins off in the lower battery box and ditch the lid. Works like a champ!!

I've also used Yellow Top's with zero issues, but that was before they started being made in Mexico..

Update: Odyssey battery (31M-PC2150S) still kicking @ss and taking names. :horns:

Scarsman · Jan 17, 2015

Yep! Best you can get. Mine is a Sears Die Hard Platinum. I confirmed with Odyssey that the Die Hard Platinum are indeed genuine Odyssey batteries with a gray case instead of orange. And the best part is a much lower price!
