Best chassis battery purchase chassis options?

[saflyer]

I purchased my 2005 HR Ambassador about 11 1/2 years ago. Still have the batteries that were in it on purchase. Today they said “Replace us”. What advice is there for replacing them?

[Ivan K]

If they lasted  and worked good for 11 years, I'd say go with the same! That's a great lifespan.

Are we talking about group 31 batteries or an 8D battery?

Please post the brand name and size of those long lasting batteries

That’s quite a track record.  FWIW…. Most are using the Interstate 31 MHD 950. The 750’s are too weak.  Monaco dropped back to them as a “cost cutting” measure.  BUT….they are a bit PUNY.  Trust me…I upgraded mine to the 950’s.

Which batteries, chassis or coach? 

What were the original brand?

If you don't use them (discharge / charge cycles) by staying in one spot all the time I'd say replace with Costco / Sam's / Walmart.  If you want the best coach batteries then Trojan T105's.  If you want the best chassis batteries Interstate Group 31 950 AGM's (Tom's recommendation).

*BUT* . . . . if you want to go whole hog do a lithium (LiPO4) coach conversion with a giant solar array on the roof and Blue Sea charging system.  The possibilities are pretty endless.

Keep us posted.

Odyssey batteries only way to go....huge power, 99.9% pure lead lasy years, still got mine on both chassis and house for 14 years not.  They cost but never let you down.

I’ll have to dig them out. They’re hidden behind the coach batteries. Will check type and brand and get back. Like the idea of going with the same due to their success but I’ve gotten indications the industry has changed in recent years so what was good before may not be now.

Duracell. Part no. 31C so I think that would be a Group 31. 950 CCA

If you go with lead acid batteries, I suggest you add thermoil to them.

This is the one I went with. With military discount, and current 20% sale each were about $150 out the door. But I’ve always been a fan of NAPA batteries.

I bought my set of group 31C batteries at Sam's Club, $135.

We do know that most battery brands are made by one of 3 different companies, right? 

Even in the photo above the Duracell is made by East Penn Mfg

After having very short life from Optima batteries, I switched to Odyssey in my collector cars.
I've had great service from them, up to 10 years.  I do keep them on a battery minder.

I just had to replace the original Group 31 950CCA wet cell battery in my Generac generator.
That battery was dated 2014, so it lasted 10 years as well, with a maintainer.
Optima prices have gone way up, so I decided to try another AGM brand, Weize, which had good reviews.

If it lasts in my genset, I may try them in the coach next time.

Once you put oil into a battery you cannot use an hydrometer to test the battery.

Duracell available Sams Club 134.52 on line or check store for instock. Last I purchased were Startrite by East Penn from Napa on sale for 100.00 ea. in Casa Grande, AZ. are 925 at 0 but only have 6 month warranty. Been in for 16 mons. and Napa is everywhere. Also replaced 8/6V deep/cycle house batteries with 2/8D East Penn Manufactered batts. My experiance with 8Ds is 6 to 8 years with non deep cycle. Dry camping for us is two nights in a Walmart or a casino or racetrack. Jenny needs exersize anyways!🤑
