Truss57 Posted January 24, 2022 Share Posted January 24, 2022 (edited) Does anyone know when you order the dual battery option in a 2022 F350 where the 2nd battery is located?? I am ordering the 7.3L engine. Thanks! Edited January 24, 2022 by Truss57 Quote Link to comment Share on other sites More sharing options...
Forderorder Posted January 24, 2022 Share Posted January 24, 2022 Which engine? Here's 6.7: https://www.youtube.com/watch?v=Xw8Y5soC3-o I believe there was a change one of the years as far as the passenger side battery being in front of the air box, but now it's behind the air box. 2 Quote Link to comment Share on other sites More sharing options...
Kory04 Posted January 24, 2022 Share Posted January 24, 2022 (edited) The extra battery is on the left side above the fender, main battery on right side above fender. I have the 7.3 Edited January 24, 2022 by Kory04 1 Quote Link to comment Share on other sites More sharing options...
d232799 Posted January 24, 2022 Share Posted January 24, 2022 Guess its needed with the Plow Package, but no matter what, the 7.3 is AWESOME...you'll love it. 2 Quote Link to comment Share on other sites More sharing options...
Mchom Posted January 28, 2022 Share Posted January 28, 2022 Which battery is primary battery or they both tied together? Just wondering about adding a jumper block at rear, which battery should I connect to Quote Link to comment Share on other sites More sharing options...

I'd say if you don't have an electrical schematic for your truck year, are not very skilled in electrical systems, can make wiring harnesses and know how to integrate into an existing system, install battery tray, add fuse or relay circuits, it will turn out to be a mess. Not to mention your warranty will be voided. Electrical fires have occurred on unmodified trucks so if you had an electrical fire and your insurance company discovered the electrical system was modified, they will most likely deny a claim and you may get nothing. The only real reason for dual batteries is diesel engine starting current draw or loaded trucks that have a ton of accessories, so adding a second battery will be no advantage. If your engine is running, the alternator has all the capacity to keep up with all electrical demand allowable thru configured accessories. First question you should ask is, why do I need more battery capacity? If you really need two batteries, need to buy it already included, entire electrical system is a system design, and the wiring harnesses are probably completely different for trucks with dual batteries vs. single. Sorry for being Debbie Downer but some things should not be modified and in my opinion, adding dual batteries to a new Super Duty would be a bad idea, but I've been proven wrong before so take my advice with a grain of salt. 787Toolman 1 Quote Link to comment Share on other sites More sharing options...

Not always the case! Surge loads can kill alternators, even on "as-configured" or OEM anticipated loads. 1 hour ago, 787Toolman said: First question you should ask is, why do I need more battery capacity? If you really need two batteries, need to buy it already included, entire electrical system is a system design, and the wiring harnesses are probably completely different for trucks with dual batteries vs. single. In my experience, this is simply an additional heavy cable as some trucks even charge from the same terminal. Certain OEM packages may have the second battery tied to a specific draw (IE: Snow Plow prep, camper prep, ect). That is just as simple, with only an additional wire or two needed. Camper use is a very common example of why you would want to install a second battery where one may not exist currently. 1 Quote Link to comment Share on other sites More sharing options...
Misnjak Posted February 16, 2022 Share Posted February 16, 2022 You think it necessary for 2nd battery if just adding some led light bars and fog lights and train horn or not really needed? Quote Link to comment Share on other sites More sharing options...
winkzoot Posted February 16, 2022 Share Posted February 16, 2022 Probably not but when I read the order guide I saw this. So I added it to my build. (7.3 CCSB) NOTE 3: Dual Battery (86M) recommended with 6.2L or 7.3L Gasoline Engines; See Body Builders Layout Book for details Quote Link to comment Share on other sites More sharing options...

787Toolman Posted February 17, 2022 Share Posted February 17, 2022 I know this thread topic was originally asking which side of the truck the secondary battery is located. I'm not certain but I know they can't both be on the same side, instead one is located on each side. I have a 2017 service CD and below are the 4 pages for 2017 F350 with 6.2L gas with one and two batteries and 6.7L diesel with dual batteries and one and two alternators. Doesn't show dual alternators for 2017 for gas engine. Diesel trucks always have dual batteries and one or two alternators, gas trucks can have optional dual batteries but single alternator only. Since this is slightly dated info, the 7.3L gasser might be different and later models could also be different, but this info is the basis for this generation of Super Duty Trucks starting in 2017. I'll look to see if F250 is same as F350, but I assume for now they are exact same. 787Toolman 1 Quote Link to comment Share on other sites More sharing options...
IUEC135ELEVATOR Posted February 17, 2022 Share Posted February 17, 2022 (edited) Dual batteries is a meer novelty for MOST people that buy the option.... with that being said- If you have a high current draw use...cranking amps, massive winch for work, massive inverter where you are powering multiple power tools, power outage situations, off grid camping/dry camp recharging dual 6v or 14v lithiums, 240vac limited use inverter for ...well whatever. (Pun intended...heheheh???) Dual batteries and dual alternators have a great use... If you are not doing any of that..... the Dual batteries and dual alternators really don't have any benefit, except make some people go....ohhhhh ahhhhh??? But...... if you do lose a battery you can still use your truck with your other battery (stipulations) and same with the alternator oh, that one goes one will run the truck(stipulations) Edit: Also if you are planning on having a procharger the second alternator will have to be removed... I will be removing the second alternator on my truck and see if I can machine out bracket oh, and find a spot to remount it..... the machining and belt change is not a problem. I have not looked yet but I fear the worst on just finding a place to mount the second alternator. If there is a spot it probably end up being the most ridiculous bracket design ever??? Although if I machine out 20 extra... I can probably use these brackets to pay for my ProCharger???

Kory04 Posted February 17, 2022 Share Posted February 17, 2022 (edited) I have ran gas trucks with single battery/single alternator for years, operating a 950lbs snow plow without issue, and that is a big power draw. I did not want dual batteries/alternator on my new truck, but it was required when I added the upfitter switches I believe. Funny that the plow/camper package didn't require it but the switches did. I'm tempted to remove the extra alternator and battery, as it seems unnecessary to me. I would have to check again, but I believe the two alternators looked different, so even If I removed one and stored for a while, it may not bolt on to the other bracket when the other alternator quits working someday Edited February 17, 2022 by Kory04 Quote Link to comment Share on other sites More sharing options...
River Wild Posted February 17, 2022 Share Posted February 17, 2022 The upfitter switches is the trigger on a gasser so I will have them too and didn't want it either. Dual batts and alts were not needed in 2017 so might be interesting as to why now. Quote Link to comment Share on other sites More sharing options...
winkzoot Posted February 17, 2022 Share Posted February 17, 2022 On the lariat adding the upfitter switches added the 240 amp alternator but did not add dual batteries on the configuration tool. Quote Link to comment Share on other sites More sharing options...

787Toolman Posted February 20, 2022 Share Posted February 20, 2022 All, I ran across this in 2022 order guide, not dual battery specific per se but kind of related since it's the alternator selection for each model and engine choice along with certain options that dictate which alternator is used, when dual batteries are used. This table may actually provide the clearest understanding of when single or dual alternators result from trim choice, engine choice, option selection including dual batteries and how each is packaged. 787Toolman Quote Link to comment Share on other sites More sharing options...
River Wild Posted February 23, 2022 Share Posted February 23, 2022 I was looking at the order guide the other day and don't see why dual batteries would have been "required". I'm asking my dealer to verify and remove the option. All I know is at the time on the Ford Build site, it kept adding dual batts when I selected the upfitter switches.

Except for the additional things to break down. Quote Link to comment Share on other sites More sharing options...
