Some of the answers depend on the vehicle and its charging system and available space. I looked at a bunch of fridges and settled on an Indel B 50. Price is right and it works like a charm. Used it as a freezer on a couple of Arizona trips at the beginning of the month and it got down to -21C...

The better quality strips come with good tape, not so much on the cheaper Chinese stuff. The good tape is 3M VHB (Very High Bond) and UHB (Ultra High Bond). I have found small rolls of VHB on Amazon and the UHB is available from some industrial suppliers. The trick is to find the roll size...

That's pretty much the way my Dodge is set up. Everything runs off the 2150 starting battery, except for the refrigerator connected directly to the Optima Blues. But, my isolators and switches are set up so that I can add one or both of the Optimas into the system whenever I choose (nothing...

Obviously not for everyone. That is why, when I recently bought a 31M for my Tundra, I went with a Northstar. Same physical size as the Odyssey, same CCA, slightly better reserve capacity (220 mins vs 205mins), same price range. Northstar rep (obviously biased) told me that the Northstar does...

More news! Odyssey and Ctek disagree about which chargers are appropriate for which batteries!!!! I just got off the phone with Odyssey. Kathy in tech support told me that the Ctek 25000 is not "ideal" for the 2150/PM1, but that it will work better than the 7002, and that is why it's on their...

Not trying to beat a dead horse here, but I have some new info. Since I'm thinking about getting another charger for my 2150, I refreshed my memory on the Odyssey charger recommendations (http://www.odysseybattery.com/documents/ODYSSEY_approved_12V_chargers.pdf ) and on the Ctek charger specs...

Can't really disagree with anything you state, except for the 14V range floor. My original alternator in the Dodge (160 amp) was often in the 14.2-14.3V range at cruising speeds, and would occasionally kiss 14.6V, but only briefly. Odyssey told me repeatedly (because I can be stubborn) that my...

Per my conversations with Odyssey, recovering these batteries will be only a very temporary fix. The sulfation is a vicious cycle, and once you recover the battery the sulfation will start again because of the characteristics of the truck's charging system. With this particular battery, I...

I ran that setup for years in my old GMC with stock 105 amp alternator, no issues. The 2150/PM1 is a different animal and requires different care and feeding.

Can't hurt, but you'll still need a conditioning charger. I just installed a 270 amp alternator in my Dodge (285 amps max, 116 amps at idle) to feed my Odysssey 2150 and two Optima Blue dual purpose G34s. Still hooking up to a conditioning charger. Bruce Essig, one of Odyssey's founders, does...

A low-amp charger will charge a 2150 just fine, as long as the 2150/PM1 is in perfect condition. Your 2150 will never be in perfect condition because of the charging characteristics of the Toy's alternator. Once the sulfation starts (inevitable with that vehicle), the low-amp charger will not...

I just found this in one of your earlier posts: I think that charger, combined with the Toyota's relatively low alternator output, is the crux of your problem. The Toy's alternator can't adequately feed the battery, so it is sulfating. The NOCO charger does not put out enough amperage to...

That is a big drop in an hour, but the most important detail seems to be that the battery is not fully charged unless it stabilizes at 12.84V or higher. After 18 hours on the charger, I have to wonder if the charger is doing what it is supposed to do. Assuming that it is a conditioning charger...

Without knowing how long you were running the truck, it seems there may be issues with that battery. Full resting open circuit voltage (OCV) on a PM1 is 12.84V or higher. Anything less than that after you flash off the surface charge or let it rest for about eight hours indicates sulfation...

I was in the desert east of Yuma for most of the first two weeks in September, and daytime highs averaged around 111F, with the highest day at 128F (two separate thermometers). Had an Indel B fridge in the back seat of the truck hooked to a pair of new Optima G34 Blue dual purpose batteries...

You can look it up on the Odyssey web site, but I'm pretty sure they say that anything below 10.6V can damage the battery. They have a chart on one of their tech pages that shows percent of charge at various voltage levels for their different batteries. All Odysseys are claimed to be deep...

Ah, Artec vs Artex! Artex makes marine and aviation safety stuff and I couldn't figure out how you were using one of their products to mount a battery. My Tundra is a CrewMax and I'm not willing to sacrifice the rear seat, so still looking for a mounting spot. There is no room under the hood...

I assume these are going into your Tundra. Can you post a link for the Artex bracket? Thanks. I have a Northstar 31M that I will be installing in my 2008 Tundra as the main battery, but I'm trying to figure out where to put a second battery.

Seems to be more complicated than that. I spoke with Northstar a few months ago when I was trying to sort out some battery issues on my truck, and they told me that Sears was switching the Platinum AGM contract from Odyssey to Northtstar. When I went into my local Sears Auto Center in July or...

I have an '05 Power Wagon and it is by far the best truck I have ever owned. Can't get a PW with a diesel, but you can build a diesel to near PW capability, but not cheap. The big problems with a diesel PW would be weight and overall length, because they couldn't hide the the winch where it is...
