AGM Worth the extra $50?

Well the battery in my other car died today, it was a Napa battery from 2017. I'm thinking about replacing the one in my Taco as well as it's on the original from 2017 and they both use the same battery, would you guys say it's worth the extra $50 to go with an AGM battery? Both Costco and Walmart have a $50 difference in price and I've always had good luck with their batteries (5+ years) but never bought AGM.

 

The Walmart AGM for $150. is a good battery. I've had mine in my 2020 for 20 months with zero issues.

FYI, I have not used a wet acid battery for over 25 years. IMO, they SUCK!

 

Just keep in mind that AGM prefer to be charged between 14.4 and 14.8v, your alternator charges to 13.9. Not sure how to get around that on a third gen besides putting it on a charger once a month or so. I'm running one and added a solar panel to help with keeping it topped off

 

You can modify the alternator voltage with vF tuner in 2016+

 

Don't listen to this charging conspiracy group. I've run my AGM in my stock 2020 for over 20 months, and it always reads 12.9~13.1 volts after the engine is shut down.

Any voltage over 12.8 is a full charge on an AGM. If running an AGM on a Tacoma stock system was a problem, I would have seen some issue with my AGM.

 

The only problem you'll notice is when you replace it in another year or so instead of 3 more years

 

Keep repeating the lie, someone will believe you, just not me. See I've actually tried this AGM, and it works fine. You have not, you are just being a forum Parret.

 

Two tangible benefits I see with AGM:
The flooded batteries have vent holes which can leak acid off-road on steep inclines or off-camber.
The higher cranking amp rating of AGM means you can go with a smaller battery. I'm running an Optima Red 35 which is 20 lbs lighter than the OEM 24F.

 

Lasted 4 years. Why change and pay extra?

pretty normal lifespan.

 

Literally no one who crawls on this forum has incline issue with lead acid batteries.

 

It's spelled Parrot. And it's not a lie. It's a fact they prefer to be charged higher to maximize lifespan. If you want to call me names over something as trivial as a battery, you can go fuck yourself

I've observed acid trickling out of the vent holes just transporting batteries in my car's footwell. It does dry out fairly quick so you won't notice it under the hood except for additional rust on the battery mount platform. I suspect it's the reason Toyota put the white plastic tray under the battery.

 

And yet another thread turns into a pissing match lol.

 

My ran an Optima Red Top for 5 years in two trucks at stock charging voltage with no issues. After 5 years it was still working fine but I preemptively replaced it with another Red Top. My understanding is the lower charging voltage just reduces the available battery capacity, e.g. it'll power a fridge for only 3 days instead of 4 days, etc.

For 3rd gens (especially 2016-2019 models) a tune is highly recommended, so it'll be a good opportunity to flash the ECM to the AGM charging voltage, but it's by no means a necessity. If a flooded battery is installed in the future, the ECM would need to be reflashed to the stock voltage to avoid damaging the battery.

 

^this
You just get more usable power. It may last slightly longer but not enough I’d consider it significant

I ran mine for over a year before voltage modifications were even possible

 

^100%

Lead acid batteries have been leaking all over shit for 150 years.
And when they're not leaking, they're busy off gassing Hydrogen to slowly oxidize anything in the immediate vicinity.
My last Optima lasted 10 years. I'm on year #9 with a Red Top in the family car and have a nearly new 3 year old one in the Tacoma.
Got over 8 years out of whatever AGM Kubota put in my last ZTR mower without even putting it on a tender during the winter months.
In my ever growing experience with AGM batteries, I've more than made my money back in longevity and lack of one type of maintenance or another.

Now then again, every generation before us successfully endured lead acid batteries, so there's that.

 

He's a dick who knows everything and has never been wrong before.

Except for spelling, or how agm batteries work I guess. Other than that, he's never been wrong before.

 

...or just stay with a flooded cell and avoid the extra bullshit and save $50.

Seems like a big hassle for such little gain.

I'm fine with Walmart flooded cell batteries.

 

On another note, Lt. Dangle, you're responsible for me wasting a lot of time watching old Reno911 clips on YT, that I would have otherwise forever forgotten.

Humor that has forever been taken from us.
