I am in need of a new battery for my truck. Doing some research I found
for the same price there are 2 batteries of the same series that will
fit . Both are the same price. However one is a size 35 and the other
is a 24F. The 35 is rated for 640 cca and 100 minutes reserve weight of
about 40 pounds. The 24F is rated for 750 cca and 120 minutes reserve
and 45 pounds.

It just seems to me that there would be a price difference especially
as one weighs about 5 pounds more than the other and has a higher
rating.

It is that way for two different brands at two different chanins ,
Autozone and Advance Auto.

But will they both fit? Check the terminal location.

The web pages that list the batteries say they will all fit. The
terminal locations are all on the same side.

Ont thing that puzzles me is one of the batteries weighs more but has
less CCA but a longer reserve.

One would think that if there is almost a 10 pound difference in weight
there would be a difference is price. But all of them are $ 180.

You wrote that the heavier one has higher CCA and reserve.

Lead runs about a dollar a pound but all considered cost may be
overridden by other things like production volume.

If both are suitable for your truck, I would buy the heavier one.

I did a little more looking and found another odd thing. There is a 3rd
battery that fits from the web page. it is a # 27F.

The 27 weighs about 5 lb more than the 24 and 10 lb more than the other
one. It has less CCA but more reserve than the 24. Must be something
in the way it is made.

I will have to take the dementions out to my truck and see if the larger
one will fit.

If lead is a dollar a pound it looks like there should be a difference
in the prices of the 3 batteries, but there is not.

They all have the same 3 year replacement warrenty .

Guess that I will go with the the 27 as it is heavier and I live in the
south where the CCA is not all that important and it is only a 4
cylinder engine.

The USD5-10 cost of that additional Pb is in the noise
for a USD300+ battery. It's more important for the
manufacturer to compete on price - it's not like they're
taking a loss on the battery, just not as much profit.

As for Frank's advice to buy the heavier battery, that's also
iffy - additional weight adversely affects fuel milage of
the vehicle, which costs more in the long run.

Bigger battery should last longer but I would buy the one recommended
for your truck.

I have seen several examples where cost depends on volume. Usually the
larger the volume the lower the cost.

No more than I drive the truck the extra 5 to 10 pounds is not an issue.
I put less than 5,000 per year on the truck. I even started using the
ethanol free in one of the cars and truck because they sit a long time
before fillups.

I want to get the longest life out of a battery as it would cost more in
gas just to go and get one plus the inconvience of doing it.

I've always had good luck with car batteries.
For my old riding mower I had a WalMart battery fail
after just 2-3 years but the TSC battery lasted many years.

Best riding mower battery I had was a John Deere lawn tractor origional
battery. I usually have good luck with car batteries, but did have one
to fail in about 2 years but only cost me a few dollars for a
replacement due to the warrenty.

About 50 years ago I worked at a Sears store changing tires and
batteries. Fellow came in and had a bad battery . It had 2 months left
on the warrenty. He was all smiles because he thought he would get a
new one free. Being prorated he got less than a dollar off on a new
one. No smiles after that.

EverStart-Maxx
24F, 750 CCA, 3 year free replacement warranty.
44.4 lbs, 10.95 x 6 x 9 Inches
$89

It's not listed on the website, but it appears (via some searches) that
the reserve is 130 min.

https://www.walmart.com/ip/EverStart-Maxx-Lead-Acid-Automotive-Battery-Group-Size-24F/28275657

Lots of folks I know swear by the EverStart MAXX line. I just bought one a
few months ago. We'll see how it handles the upcoming winter.

With these two batteries, the difference in size is relatively minute.
Group 24F batteries measure 10.3 x 6.8 x 8.9, whereas the Group 35
batteries measure 9.1 x 6.9 x 8.9. Immediately you can see that the
24F battery is that bit longer than the Group 35 battery. Which is
specified? Will the other actually fit properly?

One is likely more common than the other - The 24F has been a
"standard" for decades, as the reverse terminal (Ford) version of the
original "standard" 24 series battery - The original "small" battery
was the 22 and the original "large" battery was the 27. Looking at a
24F battery with the terminals away from you the positive terminal was
to the left, while a 24 (or 24R) the positive was on the right. The
same distinction holds for the 22 and 27 series batteries.

There is a difference in the "hold downs" between a 24F and a 35 as
well. The 24 used a hold-down that we t over the battery or a clamp
that gripped the l,ong side of the battery IIRC, while the 37 has
notches on ther short end of the battery for hold-downs. I have been
away from everyday contact with car batteriesfor a couple decades so
my recollection may not be 100% - so CHECK!!!
IF the 24F will fit properly, and the hold-downs will hold it
securely without damage, I would install the 24F

If the tray will accept the 27 series it is a more sumstantial

I will go with the 24F and save my .001mpg as the price of gas is going
up.

I looked in the truck and the one in there now is a 24F. It just fits
in the tray. I could put in the 27 but one end or maybe both ends would
hang out over the tray that has about a 1/4 inch lip around it.

The web page said the 27 would fit. It would if I did not mind it
hanging out about an inch on each end of the battery tray.

I always buy the biggest battery that will fit in the hole. There
usually isn't much price difference if any between batteries of the
same series (trade name, warranty etc) no matter what size they are.
The "F" stands for Ford but it really just means which side the plus
and minus terminals are on. Ford isn't the only one to do it
"backward" (or correctly).

My suspicion is the difference between Walmart batteries is just how
long the replacement warranty lasts. I just had a cheap one go 7 years
in my boat (the "one year" $54) and the Maxx 3 year in my wife's
Lincoln went bad in a year. (open cell). Walmart is good about the
warranty tho. I think you could take one in with a bullet hole in it
and they would replace it no questions asked.
The one in my boat probably would start a car but a Yamaha needs the
full voltage for the electronics or it won't go.

If the 24F was original equipment and the tray doesn't fit a 27,
definitely go with the 24F. On some vehicles a 27 tray can be fitted
as an "option" - on some it can't.

Only matters if the cables don't reach the terminals. Had tht happen
many years ago on a car.

CCA is all about surface area. The trade off of increasing the surface
area is a more fragile plate.

Johnson Controls makes most of the car batteries sold in the US. More
often than you'd think, the only differences among the different retail
brands are the labels and the price.

Here's some objective data.

Consumer Reports has a couple rated as Best Buys. The article say they put more emphasis on
longevity than other factors. The north designation means they're good for cold climates.
Everstart Maxx-24FN (north). $90
Everstart Maxx-35N. (north). $90

Many things are made by one or two companies. As you mentioned all that
is different is the label and price. Sometimes one company will make
several items of different qualities. AS the old Sears catalog, good,
better, best.

Looking it up seems that Johnson Controls or a sell off of the company
makes many brands. Then the ones sold at Autozone and Advanced may be
made by several companies.

One never knows what company actually makes things any more. Sort of
like the Jeeps used to be. You had to know almost what hour of the day
the Jeep was made to tell what parts were in it at the time.

It is usually in the fine print on the label. Johnson Controls seems
to be the most prevalent. Union Carbide is the other big US
manufacturer. Other than OEM supplied batteries on new foreign cars,
that is usually what you see.

It is NOT just having the cables reach. The reason for "reversed"
batteries is to keep the live side as far away as possible from
grounded items that could contact the postive and short. (and in many
cases so that if someone takes the live off first there is little
danger of shorting the wrench to ground)
It also helps prevent the battery shorting in a colission as the
grounded terminal is closest to the parts most likely to get pushed to
the battery (inner fender) and the postsa are farthest from the rad
saddle which is also quite likely to get pushed back against the
battery. On some cars even the cross bracing on the bottom of the hood
is designed so it is not over the positive terminal.
"Generally" a battery is installed with the posts at the back with
the ground to the outside - so whether right or left battery mounting
will "require" opposite polarity. If the battery is in long-ways the
positive is to the back and the terminals are towards the center of
the battery (and on SOME dual battery setups on pickup trucks they
specified 2 different batteries - with a 27 on one side and a 27F on
the other - one on either side of the engine bay) There ARE
exceptions to this of course - I've seen cars where the ground was
closest to the engine and the live was closest to the (plastic) inner
fender which allowed the shortest routing of the ground to the engine,
and the shortest live to the starter solenoid and fusebox/batery
junction.

All tnhis to say there is GENERALLY a solid engineering reason for
the battery configuration specified for the vehicle and it is USUALLY
a very good decision to stay with the specified configuration - for
numerous reasons.
