First, if you live outside of Alaska, chances are good you don’t own a .458 caliber rifle, which is overkill for hunting anything except Kodiak brown bears in North America. You probably don’t have easy access to the Mojave Desert, either, so shooting up a brand new battery is going to be inconvenient. At the very least, it’s going to take some planning.
Anyway, it’s good to know that your truck will still start, at least in the desert, if you’re being stalked by an Alaskan hunting guide. I’m not reassured enough to run out and buy a DieHard Platinum replacement battery for my own truck, but I’ll keep it in mind when the stock one bites the dust.
