AGM battery

[jkernitzki]

Yikes, most Canadians could not tolerate that prolonged extreme heat of a Phoenix summer !

A couple of unrelated questions >

Where does Phoenix get its water from ?

How does the extreme heat damage an AGM battery ?

Cheers

We get a major portion of our water from the Colorado River, and a lot is maintained in reservoirs from winter snowpack.

AGM's actually are considered better in continuous extreme heat than most any other battery chemistry, but it still degrades markedly more here than in more temperate climates.

Anecdotally, Miata's came originally with AGM (my '91 had one), and I replaced it twice in 26 years (roughly 8 years in San Diego, plus 3 or 4 years or so in AZ at the first replacement, and one more time after 4 or 5 years). So, there's that. Every conventional lead-acid battery in every other vehicle I owned since I've been in AZ was good for 24-30 months, tops.

What that means for my BS, I can't say. But, What I can say is that I'm not comfortable risking a sudden and complete failure on a mountain trail in 110F weather. So the plan is load testing at 12 and 18 months and reevaluate from there, and be ready to replace at 24 months if I don't like the trend.

Other than the famed Lytton heat wave, there's nothing in BC that would give me pause during the summer. And even that was milder than I've experienced here. Past 110F/43.5C, we don't even use numbers, we just call them "plus days". We tend to have a lot of those.

BC Winters are another story altogether. Beautiful, but you can keep them. My blood's entirely too thin for that anymore.

Come spend a summer in the Valley of the Sun--often referred to the Surface of the Sun--and let me know how you compare them. And we're not even the hottest place in the region. It's oppressive, unrelenting, and will kill you in no time. We average about 450 heat-related deaths per year, plus another roughly 450 ER visits. Granted, it's not Dubai where summer is downright painful, but still. I'll trade you any time.

When Frank Herbert wrote, "God created Arrakis to train the faithful", it was after he spent a July weekend in Phoenix.

I have been there in the summer, I like it myself. so the lytton heat wave you mention is not far from me and it is pretty much the end of the micro climate for this area I live in. I was camping during the lytton heat wave, that was actualy a heat dome over the whole area. kamloops at my place was only 0.4C cooler than lytton. even during the summer when a record is set in either, there is less than 1 degree difference. I digrees, I was saying I was camping during that, and that was the only time I wished I had a generator to run the AC.

our winter temps because of it are not that bad, the normal high is around freezing, but I work a hour away at a mine and thats a little different, usaly 10 to 20C degrees colder

Arizona eats batteries for all three meals. My daughter has to replace her car batteries every three years or so. My grandson’s battery operated motorcycles and scooters last maybe two years max. I told my daughter he’s getting a real motorcycle next. Replacing the batteries in the scooters and battery operated motorcycles is a real pain.
