Battery group size

[brokencase]

I'm sorry Ed, but you just don't get it.

The Project Farm guy has performed no long term testing in that video. I'd like to see the same tests after the batteries have been in a vehicle for three years. Maybe he'll do that at some point.

To me the most important parameter is the internal resistance of the battery. The AGMs excelled with this parameter. The other point worth noting and he demonstrated was that the AGMs charge faster.

The only takeaway that you got from that video was that the brand new EverStart performed better at -20 degrees, and therefore you think you are getting a good bargain.

And he states quite properly at 11:40 in the video regarding AGMs "handle vibration better, require no maintenance and handle deep discharging better"

What he did not say (and this is important) is that "an AGM battery can start your engine more than 60,000 times. That’s more than three times the starts you’ll get out of a standard battery."

In other words, an AGM battery will last longer.

Ed READ the facts!...from a company that has been making conventional batteries for a long time:

Religion? Hype? You are a Luddite stuck in the Dark Ages. I should probably write all this down with my feather pen on parchment and send it to you via Pony Express!

One more thing Ed, and you're not going to like it because it means more cash outlay.. But you need to buy a new charger for AGM batteries.

In fact, I don't think even your battery tenders will work with AGM. That's gonna hurt..

Ahh yes...the relentless march of technology...leaving the Luddites far behind. But we'll wave to them as we ride that train into the future.

Fare thee well oh Luddites, Replenish thy carbon cell flashlights lest ye get lost in the darkness! Fare thee well Luddites..

Todd of Project Farm near the end of the tests "I really thought the AGM batteries (Optima et al) would perform better."

It's of minimal relevance that an AGM charges maybe 30-40% faster. Unless the lights were left on in an Optima batteried car as that battery would need recharging.

Optima AGM performed poorly on the 30 minute lamp On draining ~ 40/45 amps test @ 12.2v after test end. (PF: "definitely needs recharge").

Everstart performed very well after 30 minutes drain test @ 12 6v: "PF: at 12.6 and above a battery is considered fully charged".

Everstart performed very well on CCA test, better than the Optima AGM.

PF: "I really thought the AGM batteries would perform better in CCAs." Yes, IR for the Optima was best but the Everstart IR was good.

Brokencase: "...AGMs "handle vibration better, require no maintenance and handle deep discharging better." Valid comments. For use in Scorpios, vibration is a non-issue; all batteries require cleaning tightening of battery connections.
Re deep discharging, we here aren't running bass boat outboards.

I'll stick with Everstart (or Interstate if I were a Costco member). Great bang for less buck FTW.

As I stated Ed, No life testing in that video. I don't even think the load testing he performed was very good. All the results invert to AGMs favor through the passage of time.

You rely on one youtube video as evidence yet you ignore the multitude of authoritative sources elsewhere that conclusively state the superiority of AGM over conventional batteries.

As far as a bargain pricing goes. During the sale, I paid $126 for a Weize H7 AGM battery. That is less than the price for a conventional battery from Walmart ($159). I could have purchased the Group 47 AGM for less than $100. I didn't even have to waste time or gas to drive to Walmart to get my battery. It was delivered!

Granted, I have to get rid of the old battery, but I have a shop two blocks away from me that will take it.

[Ed Lijewski]

Yes, I point to a single YouTube video by a source of Gold Standard transparent, objective and trustworthy testing and reporting.

Brokencase says: "I don't even think the load testing he performed was very good." Tell P.F. that in Comments on the video...if/If you have a specific superior manner for amperage drain testing, to see what he replies.

Brokencase cites: "the multitude of authoritative sources elsewhere that conclusively state the superiority of AGM over conventional batteries".

P.F. bought into that (hype) and so expected AGM batteries to perform better, but they didn't.

Agree the price you paid was attractive. I might have bit at that if I were battery shopping.
Except...my calculus would have heavily weighted how any warranty/exchange issue(s) would be handled and what such actions would oblige me to pay, as well concerns shipping services have re any battery.

I looked in your link to Weize and didn't see info re returns (or missed it).

Everstart still FTW!

Gawd I love it when you go into "taunt' mode...so I can slap it out of your bean . As you said, "That's gonna hurt."

Of my four chargers three work with AGM batteries. One is made by Schumacher:

Wonderful. Your battery tenders are all ready for AGM batteries.

But are you?

[Ed Lijewski]

In Project Farm I trust.

Maybe the words of you favorite battery manufacturer will sink into your head..

https://www.johnsoncontrols.com/media-c ... th-america

"AGM batteries manufactured by Johnson Controls are engineered for ever-increasing vehicle demands, including:

Superior starting power even at low states of charge
Reliability in harsh weather and extreme conditions
Excellent durability in high-load applications"

https://www.johnsoncontrols.com/media-c ... on-demands

The problem, Ed, is you have no personal long term experience with AGM batteries. Neither does the Project Farm guy...at least not yet.
But I do.

It really doesn't matter, Over time they will just stop making wet cell batteries. If they do, they will cost more due to low demand.
A major reason for this (outside of OEM vehicle requirements) is that shipping AGM batteries is easier and safer.

[Ed Lijewski]

Weize batteries are made in China.

You have been silent on Weize warranty and actual purchasers experiences.

Walmart warranty process is transparent and efficient from experience.

Weize warranty process is a hassle.

Wait a sec, Ed...

You cherry picked a few negative reviews. Please don't cherry pick to make your argument. It is insincere.
What about all the positive reviews? Remember there is a 4.6 out of 5 overall review rating for Weize on Amazon

And for god sakes, can you resize your cell phone image capture posts? They are dang irritatingly large.
Just post a link to them.

Quite a few negative reviews on EverStarts here, similar to my experiences:

https://bobistheoilguy.com/forums/threa ... nt.367130/

And for what it's worth. my Weize came delivered at 12.7 volts and 2.9 milliohm internal resistance. The best I have measured on any car battery.

But the point has been made. Ed has no experience with AGM batteries, therefore all his information is second hand and what he chooses to pick off the web.

[Ed Lijewski]

The Chinesium Weize warranty process is flaky. Period.

You wrote: "You cherry picked a few negative reviews.What about all the positive reviews? Remember there is a 4.6 out of 5 overall review rating on Amazon."

Damn, you're dense. From the beginning of this thread I expressed INTEREST without prejudice in knowing about purchasers' experiences re warranty issue coverage You avoided addressing that. The screenshots above directly speak to it.

And do you really think informed consumers are so easily swayed in their search for warranty coverage experiences just by positive reviews which don't speak to warranty experiences?

Re your eyeballs irritation; maybe use sunglasses?

YMMV

[brokencase]

I read...
"however the manufacturer reached out and fully refunded me the cost of the battery. They are prompt in their response time to the customers"

Works for me.

Those negative reviews appear to be "out of the box" failures. Possibly damage in shipment or poor handling by the customer themselves. Especially the guy who got all sorts of error codes as soon as he installed the battery.

And, Oh yeah, its super convenient having the EverStart warranty where you buy the battery, it fails under a year and then you go get a replacement and it fails a year later.

But granted Ed, I can't attest to the long term on the Weize AGM. I can only attest to longevity of AGM's in general for which I have experience with and you obviously do not. I provided ample evidence from noted battery manufacturers that you yourself trust, that provide technical details why AGMs are far superior to conventional batteries.

Where we widely differ is on our experience with EverStarts. I will never buy one again. But to this I will add...It may not be the EverStart batteries themselves that is the problem, but the poor handling they incur in the Walmart retail environment. i.e., clumsy Walmart staff tossing them into the display. Clumsy consumers pulling a battery out of the display, realizing they got the wrong one, dropping it on the floor, returning back into the display etc.. I think this is a reality one must consider.

My Weize battery came well packed, 2 inches of foam all around, and it tested wonderfully out of the box.

None the less, if I experience a premature failure of the Wieze battery (36 months) I will post on the forum describing the outcome.
But I expect at least six years out of this battery, perhaps more.

Walmart today: one replaced battery, non-Everstart
