Soooo.... How does the vehicle know the difference between an AGM vs Lead Acid battery?

body control module senses charge amount needed for electrical load - better charge acceptance as well as better cycling life along with the ability to run at a low state of charge. AGM batteries recombines the gasses, which are produced internally, back into liquid.

Nah, I bought 3 GMs--2 chevys and 1 GMC in the last 10 years---all junk with the AFM and all used oil. Last one was a 2018 and it used oil from day 1. Quart every 200 miles or so and GM wouldn't do anything about it. Fuel mileage sucked. Traded it in with 8000 miles on it for an F150 with 5.0 10 speed and get anywhere from 23-26 MPG on highway ---best any GM got was maybe 20 if I kept it under 70. 53,000 on the Ford and no oil usage either.

Maybe you should put one of those wonderful Triton motors in your 55.

hell no-----this isn't a triton motor---those things are a mechanic's nightmare just changing the plugs.

The way they blow them out half the job is done.

yeah, that too---and usually on cylinders 3 and 4---the hardest to get to. I've installed a few helicoils over the years. Customers didn't like the prices.

Look at Rock Auto, the deka agm seems reasonably priced. Cosco or if you have a Batteries +, check them out.

Batteries, batteries, batteries, man i go through a ton at work. Trucks, backhoes, skid steers, pavers, seems like 3 years is now a good lifespan for any battery now a days. And the 24 Volt batteries for the milling machines, well, i dont know exactly how much they cost, but they sure do look like $500 batteries. i have the guys dating when we install batteries. i would really like to know how long they are lasting us.

Batteries 😁 Friend just told me his new electric GM just froze his batteries…Rig just hit 5000 miles on it. Didn’t like having to call the dealership to send out their flatbed to pick it up. He has decided electric vehicles in Minnesota winters is not a good idea.

I ended up getting a friend's employee discount at Oreilley's. $178

Currently have a 2016 Ford F-150 V8, 92,000 miles going on 7 years with no problems. I've had Ford, Chevrolet and even a Ram. Ford or Chevy both good vehicles. The Ram was OK but gas milage was terrible. Didn't keep it long enough to say anything else.

I have to remember to go to a certain mom and pop parts store. They buy pallets of Deka batteries with cosmetic blemishes. Only heard good news about the prices and the quality.

All of this battery talk made me recall a true story on a 1963 Cadillac I owned for over 25 years. The original owner told me that when the car was 11 years old in 1974 the car was using the original Delco battery installed at the factory. They were so impressed that they wrote Delco to express their satisfaction. Apparently Delco was impressed too as they sent a film crew out to film a television commercial using the car with the original owners. The day after the filming the battery died, apparently filming the commercial with constant starts, rolling the power windows up and down, etc. was just to much for the old battery. I asked the original owner if Delco gave them a new battery and he said no. I said well you certainly put a Delco back in it and he said no, a Sears battery was cheaper. So much for loyalty!! 😂

then quit bitching about the cost of the battery

 

[KRUNK !!!!]

my neighbor and I have been re-jouvinating old batteries......success rate of prolly 85%.......I hate spending the cash for new when most all "dead" batterys can be brought back to life

Buddy of mine had his battery go flat, he tried to recharge it but would not charge, took it back to the store, the store owner had a charger that would override the charging capacity of chargers when they do not sense a voltage, has been fine since.

yup .... ya gotta pass enough AMPS thu the battery plates to dissolve the sulfation .....it takes several "passes"...and cool downs......also the hydrogen boils out of the cells while this happens .....make sure there is PLENTY of ventilation.....then let the battery completely cool down.......charge it as normal....and wh-la.....works like new

Yes, if your battery is really, really dead, a newer type charger might not charge it but an old fashioned charger will at least try to charge it no matter what. Keep one old charger around. I have a little 8 amp charger I got for Christmas 40 years ago that works just fine. (also a 40 amp I got for free)
