Since I just picked up a new fridge, figured I should upgrade the battery as well since mine struggles after 20 minutes of stereo use.

Found the Odyssey Battery 34R-PC1500T Heavy Duty Commercial Battery for $229 with free shipping and no tax at Autoplicity.

Found a coupon for a whopping 2% off as well, (2offtotal) bringing my total down to $224.41

Since Sears no longer carries the Platinum series (discontinued 15 months ago according to the sales tech I spoke with) this is one of the best options out there for a stock size high end AGM battery.

Just wanted to pass along the info since this is $25 less than I could find it anywhere else for shipping to NV (two other places have similar price but wanted $18 tax)

If you can order with no tax, 4 Wheel Parts and 4WD.com both have the battery for $229 and free shipping as well.

Hi tigger,

I actually bought the Odyssey 'EXTREME' agm battery last year; great battery:



The wife needed a battery for her Camery but didn't want to spring the extra $100 bucks for the Odyssey so I got her the 'EXIDE edge'. It was around $169 but when I read up on it, it is a very capable agm with many features rivaling the Odyssey extreme; Had I known about it before, I probably would have gotten the exide edge:



I really can see no difference except the one I got her was a little smaller as far as the CCA; hers was 710 cca with a 120 min RC and mine, 900 cca w/125 min RC, but other than that, they're the same. PS: I'm glad you got a really good deal on yours!

So people may understand RC/Ah's

You'd want to know your Ah's for running a fridge

Exactly, Pat! I find it humorous to see people putting in dual battery setups only because they are going to run a fridge over a weekend of camping! If they only knew what the draw of these units were, and understood the concept of amp-hours, they'd probably never bother with two batteries in their rigs.

Here's the draw of the ARB fridges, the other brands may be slightly higher, but shouldn't be a lot higher than these numbers.



I have the ARB 35L, as well as the same Odyssey battery Brian just bought. I just came back from a quick road trip with my ARB. I left it on in the vehicle non-stop the whole trip. I then parked it in my shop when I got back on Sunday, and only pulled it out yesterday. Vehicle started right up every time, never an issue. That's running it usually at 35-38ºF the whole time.

But hey, to each their own! Dual battery setups are still cool, and they serve a purpose if you're running tons of lighting, a winch, and a whole bunch of other electronic gagetry when the engine is off. My point is that its just not necessary with these ultra-low power consumption units. Just a good AGM battery would fit the bill.

Clicked the link and it was well over my head, can you dumb it down for me Pat?

Edit: Nevermind, flyinhawaiin's post helped.

From what I've seen, most 34R-sized AGM deep cycle batteries are around 60-70ah. The chart I posted was from an Aussie website, and those numbers are taken from ARB fridges running a bit longer due to the higher temps they run their stuff at. So, for summer with temps nearing 90-95º, I'd say that chart is relatively accurate. If its cooler, meaning the fridge is not cycling more to keep it cool inside, you'll get more time without recharging.

Its always going to be hard to determine exactly how long one can run their fridge. Age of battery, doors being opened and closed, fridge door included, will also change these numbers. Best thing I could ever recommend is to start your vehicle once every 12-18 hours if you're running in 90º+ temps or using any other power from your battery.

Yeah my plans with the fridge will be maybe 3 day weekend use, didn't seem like a second batt would be worth the hassle. I figured getting one of those antigravity starters as a backup would be simpler. I do have a Sears platinum battery now. Great info above!

Also things that may affect usage of amps are things like outside temp, inside temp (fridge sitting/running in a closed truck in the summer sun), other items drawing current (say chargers for lights, laptop, phones, etc.)

Once you figure out your "load"...you can have an idea how long your accessories can run safely given your batteries capacity. This is also why this time I'm trying to incorporate a solar panel, and a li-ion palm sized starter pack.

What????? Well pooh!!!!

Yeah, see my thread on the X2.

So not sure if this is the right thread to bump, but I also just purchased the same battery.

I plan to use it to power my ARB fridge this weekend camping. I've read conflicting data as to how much I can run the volts down while still getting the car to start? I'd like to monitor it periodically but don't know where that cutoff number should be.

You should be able to start the vehicle with any of the settings on the ARB. You should get a power pack for jumping your vehicle just in case.

While I've read that the ARB should shut off "before" killing the battery, I feel like I have also heard plenty of stories of it actually killing the battery, that's why I asked.

I do have a power pack for back up, but still would like to be on the safe side.

@flyinhawaiian01

Personally my main idea with running a dual battery set-up in the future is to off-load all the accessories (winch, lights, ect.) onto the secondary battery on an isolated circuit so that voltage spikes and variations are contained better on a circuit separate from the main vehicle's. It's probably a bit overkill, but that's how I like doing things.
