Correct battery for 2017 with tow package?

Hello everyone. And yet again I go to the most knowledgeable folks having to do with my 2017 tacoma with tow package. It is my understanding that up to 2015, a 27F battery accompanied the tacoma with a tow package. I now have determined that the 2016+ tacomas with tow package now have the 24F battery. Why is this? Can the 24F battery handle the tow package and needed power? Why did toyota stop the use of the 27F and start using the 24F? It seems to me that this is a downgrade. Is it up to me, the customer to determine if I want the extra power and thus pay, out of pocket, the purchase of a 24F at this point? Or is the 24F adequate to handle the tow package without worrying about purchasing a 27F? I thank you all in advance for your most excellent advise and knowledge.

 

Go big or go home! Group 31

 

Its just power reserve, why do you need more power reserve while towing?

24F basically has more crank and less power time

27F basically has less crank and more power time

Seems moot to me in your case, I'll take the smaller battery for weight savings

 

For stock configuration a 24F is fine but you can always go bigger if you want.

 

If I had to guess, i would think they did it for weight and to simplify the assembly line, If you want to use a 27F in these trucks then you just need the Battery Tray from a 2nd Gen with tow package

 

Why? What does a Grp 31 offer you?

 

More power but seriously, more cold cranking amps, more reserve. Down side is cost and weight.

 

CCA's, CA's and RC I understand as I worked for Interstate Battery for years. CCA's apply ONLY to cold climates and RC applies to operating the accessories while engine is off. More CCA's means nadda in most instances except really cold climates. If a vehicle requires say, 400 CA's or 500 CCA's depending upon worst climate encountered, the engine will only draw that amount. If one has 800 Amps available, that excess is just that, excess. Yer right by saying downsize is cost & weight. If Taco owners want a really cool "mod", then the best battery upgrade would be to go to an AGM. Group 31's are for guys with little pecker syndrome. Everything about an AGM is far superior than simply going with a bigger Group size.
I would venture to say 90% of vehicle owners don't check the water levels ever in their wet cell batteries and that is without a doubt the single worst thing to neglect. Summer heat increases the reaction that occurs within the battery cells and oxygen and hydrogen are released via the vents. Oxygen and hydrogen is water. When water levels go down, acid concentration goes up and battery dies a rapid death and usually rears its ugly head during the early days of cold weather when CCA's are required. If anyone has put a sealed battery in their Taco, aside from an AGM, so they don't lose water, then they need not be on this forum as sealed batteries are usually fail prematurely (after neglected wet cell type) and they are intended for sale to soccer mom's or guys driving minivans.
I will dismount the soapbox now! Thank you for your time and I look forward to the trolls.

 

I did not realize the stock battery was not maintenance free. It seems like years (many, many) since I've seen a battery that did not say something to the effect of 'maintenance free', ' do not add water', or such (industrial equipment and motorcycle excepted, but even motorcycle is mainly AGM). I guess that is what I get for shopping for batteries at wally world.

 

'Group 31's are for guys with little pecker syndrome.'

I don't have either...but that was funny as hell!

 

34,000 miles on me third gen with about 5,000 of those miles in front of my camp trailer. And no, I don't miss the Group 27 in my 2007.

Why would towing require you to have a bigger battery? I don't know about you but when I tow something my engine is running and my alternator provides all the power I need.

 

Huh? What's the relationship between the 3rd gen and the '07 and Group 27 and Group 31 batteries and where does towing fit in?

 

1. "Where does towing fit in?" The post is about towing packages: "Correct battery for 2017 tacoma with tow package"

2. "What's the relationship between the 3rd gen and the '07 and Group 27 and Group 31?" 2nd gen tow package had a Group 27. The 3rd gen towing package has a Group 24. I don't understand your question, "relationship' to a Group 31" so can't help you out there.

I guess my whole frustration with this thread is the fact that some folks seem to think a bigger battery is a better or "badder" battery. Once the vehicle is started and running at >1500 RPM's, the alternator takes over and the battery just sits and adds weight. My 07 had a Grp 27 and now my '17 Limited with tow package, has a Grp 24F and both have towed my boat up and down the Great Smokey Mountains without issue. Why anyone would think bigger is better is someone I would have liked to have sold batteries to!

 

While your truck is running may be true, but a lot of members get bigger and better batteries for running electonics while truck is off, winching and they can go hundreds of discharge cycles unlike cheaper batteries.

Plus many more expensive batteries are sealed and great for mounting in any direction and off road use. If you’re towing something, you usually have a lot of other toys to power, as well.

Personally, I like a small Honda generator which will run 2000 watts several hours on a gallon of gas.

 

I agree. I'm sure somebody at Toyota was scratching his head over the larger batteries in the 2nd gen tow package and asked, "why?", and nobody could come up with a good answer.

People will argue anything. Either are fine.

 

unless you are winching or use lots of power with the engine off, get an AGM in whatever size your truck came with and call it good.

 

doesn't a "tow package" come with a larger than stock alternator? and if so, would that determine battery size?
