H8 battery for 2021 1500 5.7 Hemi eTorque?

[FLiPMaRC]

Without a battery maintainer on the stored battery, six months would be about the limit, I think. I know Interstate checks dates and rotates stock at their independent retailers.

Why wait? If you're going to buy a battery in advance, why not install it then? What happens if you tie up $2-300 and your battery decides to enter another dimension when you're a hundred miles from home? That H8 at home on the shelf isn't going to help you any.

I didn't wait for grief. I replaced my battery at 3 years. Maybe I threw away a year's worth of battery, maybe not. But it is worth it for peace of mind. There's too much electrical stuff in these trucks to risk it.

True. Reading all the posts of dead OEM batteries had me concerned. I guess I'm going to replace mine next year (3 years). I bought it June 2021 with a Build Date of May 2021.

I'm partial to the Walmart EverStart Maxx brand. I've been using it on all my vehicles for over 10yrs. I replace every 4 years. The Everstart Platinum H8 is about $170. I might go ahead and buy one if it I ever see it in stock when I go to Walmart.

Mine (OEM) left me completley stranded and I had to interrupt a friend and have them come help.

I replaced mine then bought a NOCO jump box so I don't get stranded again

I have jump a Li-ion jump starter box in all my vehicles too.

How many years was your oem battery?

Finally got my Battery replaced. There was a sale at Sam's, it's not much of a sale but enough for me to get an ok from the wife. I attached a picture of the original battery and the little adapter that you have to removed in order for the H8 battery to fit in the battery tray.

Question ... how long can you keep a new battery on the shelf?

When I go to Walmart, Costco, or Sams, I often check if they have H8 AGM in stock. Sometimes they do, and then they run out. Can I buy one now when I see it in stock and keep it until I need it?

H7 is easy enough to find. But that elusive H8 AGM is a crap shoot at the stores. I'm worried that I can't find it stock when my stock oem battery craps out.


Also, you can get the H8 battery blanket from eBay: 5033397AE for sale | eBay

About the only concern is the diminishing warranty duration. Heads up on Costco's battery warranty. They recently switched to a 3-year pro-rated warranty. Found out last month when I replaced my Interstate battery for a full refund after 13 months based on the old warranty.

Really? I can't imagine asking my wife permission to buy anything, let alone a battery for my truck.

He was referring to a human wife, not the type in your signature.

Apparently, reading comprehension isn't your strong suit.

Yeah, me too!

Where is this said "spacer"? I upgraded my OEM battery yesterday to the H8 and can't get the hold down tab to bolt back down. Thinking this "spacer" might be the issue.

See this post.

See this post.

That was the issue. Took the battery out at work today, popped out the spacer and TAADAA. H8 fits perfectly and was able to get the hold down tab to bolt back down.

Anyone replaced their battery with H8 size instead of H7? If you do can you post a picture of it installed in your truck. I just want to see that it fits without any major modifications? thanks!

Just take out the Lil tab inside the factory battery box fit perfect.
