Jeep Compass Auxiliary Battery Replacement

[@delsinmcgrath882]

Brother, you just saved me $1,500 that the autoshop tried to charge me for this. It took me 30 minutes and had virtually no trouble at all. You are awesome!!

The Jeep compass had electrical gremlins. Dash dash warning lights would flash on, wouldn't start after just shutting it off, a true mystery. Changed the main battery, but trouble persisted. Then I discover it has two batteries and found your video. Any easy swap-out and I saved untold hundreds, if not thousand of dollars at the dealership. Thank you! Thank you!

[@judgegazza7793]

Thank you!!! You're a lifesaver. My son in law tried to get the guy at the auto parts store to change his aux battery yesterday, but only ended up worse off than when he started. You had the secrets!!! First the store guy stopped when he didn't have a T5 socket, so you told us we needed one before we got into it! Then when the guy put the battery leads back on, he put the lower positive lead on the neg side with the neg lead. Jeep really should've made that a red wire. Anyway my son in-law is all better again... Thank you!!!

[@Jimmy_Cavallo]

🌟 Is the T5 the socket size that’s needed to swap over the posts from the old to the new battery.?? Somewhere else it was said that it’s a 4 mm

[@Druhue]

Just amazing. I have very limited knowledge on car batteries and with this video I was able to do my own swap within an hour and nothing more than the battery cost. We are super strapped for cash so the importance of your videos cant be understated. Thank you!

[@mrpreparedallthetime1099]

Brother I am a Concrete Finisher. And working in construction I never find myself well I shouldn't say never but I rarely find myself working on cars both my wife and I have warranties and blah blah blah on our vehicles but when the battery died and my wife's car I went and changed it turns out there's two batteries in the car. Brother you made this job so flipping easy for me thank you so very much I will always continue to watch your videos subscribe to your channel and reach out if I need something. Thank you. You rock

[@katrichards3890]

Glad I found this channel. Really clear and concise information. My Compass wouldn’t start yesterday and when I checked the fusesI had to unhook the battery because an error message about the “vehicle is in Park“ would not go off. (It was in Park) It puzzled me because I was not aware my vehicle had two batteries. The door chime would not stop dinging, Set the neighbors dogs off and of course it was 10:30 pm. So it was a fun evening...NOT! For the record, I do not like stop/start system and I’m sure I’m not alone. But I appreciate you sharing your knowledge sir. God bless!

I'm having the same issue. My car won't start, only the lights & radio would come on & when I tried to shut it off it said the same thing to put the car in park but it was in park so now my car won't turn on at all. Did replacing the 2nd battery fix the issue for you?

[@hannabell9753]

@@mari.buen14 I know my aux battery is going bad, my car wouldn’t start today. I’m in tow different compass groups on Facebook and they recommend to go ahead and replace both. My batteries are still factory on an ‘18 so I guess it was about time. I’m worried I don’t have a memory saver and whether I need to replace one or both batteries 😬

Thank you so much. Got stuck at work last night, puzzled why I couldn’t jump start bought me a new aux battery and back on the road. 🙌🏾.

[@basshunter428]

Another reason to be glad I drive a 98 (4.0L) Wrangler and a 96 (2.3L) Ranger! 1 battery, no extra electronic GARBAGE. It's all packaged as a "we're doing this to make things more efficient and help you" scenario, but in reality it's just a bunch of expensive modules, sensors, fuses, connections that can and WILL fail probably sooner than later and how many (needless IMO) start cycles is a starter designed to last? I can tell you that driving and having a starter repeatedly cycling is cutting deeply into the starter's life (if it were without the auto-start feature). Not to mention (I have driven a Cherokee with this exact feature) it is down right annoying! Great vid!

[@jadacamp3638]

The most detailed video I have found. Not only did you explain very clearly, you also told valuable information (nut size/specs). Highly appreciated!

[@mikecup212]

Thank you for the excellent video. I just finished installing this auxiliary battery in my wife’s compass, purchased the battery on Amazon for $104, ESS light is now off, another odd thing, the check engine light was on also, bad thermostat code. But now the check engine light is off also, not sure if it will stay off, time will tell. Thanks for the very detailed instructions, I appreciate it.

This was so helpful, my mechanic didn't even think of the auxiliary battery. I changed it and it fired right up. The dead auxiliary was pulling power from the primary.😅

Hopefully just the aux battery that needs to be replaced here. Sucks having a car with two batteries, they last for a value 4ish years and the warranty is ofc 3 because they know themselves haha

Ive been a mechanic for 25yrs, a good rule of safety is when you disconnect the cables rap them with electric tap, so they don’t hit anything important. It’s especially a good idea with these newer crappier cars. I will say in 25yrs I’ve never used a torque wrench on a battery.

Awesome video Dave! Yes start/stop SUCKS! My wife has the same on her 2018 Dodge Durango which we always have to hit the button to shut off. But both batteries are under the front passenger seat. What a PITA. You make it look easy as usual))) You think they would give you the option in the EVIC display to permanetly disable it if you wanted so theres less wear and tear on the starter. But then again i guess thats more moola for the stealerships. Kudos to Dave!

Thanks for this, very helpful, question, any need to use a power saver to keep settings in the computer while disconnecting both batteries?

I never use one so I don’t see any need for it personally

[@Johnny-Wayfinder]

I work at a Walmart nearby, specifically as a TA Associate and today we had a Jeep Grand Cherokee which we had to replace the main battery of, it was an AGM battery (H5 Group Size I think). Our techs hooked up a memory saver and replaced that battery. But, when they tried to put the vehicle in gear it didn't want to work. So, that meant we had to call a tow truck to haul the jeep to the dealership so they could reset the jeep. We reimbursed the customer, but gosh dang it. Just remember to be careful when replacing the batteries on these things. You might lock up your transmission. And the price that we had to pay the dealer was like $222.58! That's by no means cheap in my book.

[@bills682]

Great video. Question to ask. Can I charge the auxiliary battery while connected and in the Jeep without having to take everything out. Just want to make sure it won't destroy any of these expensive fuses. Thanks

[@Ryzenberg78]

If anyone is curious the auxiliary battery for the start stop system is required. If it dies and you don't replace it, the system will not work obviously, but the starter will kill the main battery from typical/regular use. The starter will work like a regular system utilizing the main battery, but over time it will kill it (typically within weeks).
