Benz tech here previous gen cla(117) gla(156) super important to do both they have issues when the aux battery and the main battery are going bad the car would shut down during auto stop and not turn back on due to the battery not having enough juice to turn back on usually u would only get a message on the dash for the aux battery and the main is just starting to go out

These newer gasoline vehicles need 2 batteries? That is scam deeper than most could ever comprehend.

[@busterscrugs]

Not all of them, this is just typical Stellantis garbage.

[@ohredd9936]

This is true everyone. You must replace both of them together. And usually they are both platinum batteries.

[@hpmetabolics7558]

Maaaannn, Alex they can keep all this extra💩! Start/stop, soft closing doors, auto parking, lane assist, auto trunk open and close, hybrids...its all going to fail and be damn expensive to fix! I don't want anything newer than 2012!

[@FullMoonChronicles]

This is one of the reasons I've never bought anything newer than 2015.

[@anthonystander8814]

I’d like to add to this! If one battery is bad doesn’t mean replace both in my opinion testing each battery after giving a full charge is the proper way to do it. Been doing mechanical work for years and found that to be the best way. Save money test first!

[@ryans413]

Because both batteries work together so it’s best to replace in pairs. Just like brakes they work together you can’t just replace one side you gotta do the fronts and backs in pairs.

[@christopherrosas2738]

Well this is good to know..... thankfully I don't have a vehicle with an aux battery

[@moeal5469]

Ask them to give you a Motorcycle or ATV battery. It’s cheaper than telling them you need an auxiliary battery. It’s the same battery but they charge you more. When they hear you say Auxiliary battery. 🤑

[@samdelucia5074]

an AGM battery is far different than an atv battery

[@wethobgoblin2740]

This is why any newer mopar vehicle isn’t worth buying unless you got the money to spend on maintenance or the knowledge of doing your own work. I work at a CDJR and it breaks me seeing the charge after having both replaced at a stealership

I bough a 2012 honda civic in my country in 2015 and had around 17 000 km and i has to replace it 2 years ago witch mean it weant for around 13 years before i had to change it and yes it was the original.

[@iceman8361]

Wife got a hybrid Fusion Titanium 2019 it had super low miles on it, sat on the dealer lot over 3 months. Soon as we got it home within 2 days the aux battery went out and it had to be jumped. Took it back to the dealer we bought it from they replaced the aux battery but said the main battery was ok. 2 weeks later the main battery went out also. I went and got the bigger battery from the dealer it was the same price as the smaller battery from the parts store and had a longer warranty. No problems since then! Great tips as usual Alex!!

[@OWK000]

Lead acid batteries sulfate if they sit and then they won't hold as much as of charge. If the battery gets drained all the way and then sits there, the battery can be reduced to not being able to hold a usable charge at all. Even if deemed "dead" if not too old and corroded, sulfation is reversible by long trickle charging that any cheap trickle/maintainer plug in charger will do. It could take weeks, so it isn't very covenient and its a home fix, not a mechanic/dealer fix. Solar with a charge controller will top off lead acid even higher than a plug in trickle.

[@quinnbeauford2059]

😮 This is good to know 😊

[@nsxt290]

I really hate that start/ stop& unnecessary battery costs. You can't win either way . Auxiliary battery.... how about a rear wiper.... more useful than start/ stop

[@LawTzuTao]

Bruh! I had no idea‼️ 🤯

[@Thejdamdropper]

So genuine question, my vehicle has the start stop feature thing but i always just turn it off before i drive anywhere, could i possibly run into these problems even if i dont use it?

[@TheProdigalSon46]

I unfortunately have a 2008 malibu with the 2.4 ecotech engine which I've replaced the alternator, starter, battery AND the ECM, yet I still get a battery light on the dash. Short of removing the shething for the wiring loome to check it for any bad spots, where might my problem be?

[@tmsz28]

Not to step in for Alex, but just some tips. Gotta verify your alternator is actually good, either on the car or bench test. Bad ones make it to the store a lot, esp rebuilt ones. If it is charging, is it on the high end or low end. Low end at idle might trigger the light. Also, peep at the balancer/crank pulley. Sometimes the rubber that holds the outer & inner ring together will deteriorate, which will allow the belt to slip & the alternator won't really spin fast enough

[@TheProdigalSon46]

@tmsz28 I ordered the alternator from Amazon and it was tested and passed. The other thing that happened is that a parts store employee told me to connect a cable from the alternator to the negative post which initially fried my ecm and caused the alternator to smoke. I'm just trying to see if I'm going to have yo spend thousands of dollars to resolve the issue of the alternator not charging my system.

[@jamespalmer4945]

I purchased the bypass to the start/stop system. What does Alex say about that?

[@OWK000]

It funny how there is no amp rating on that battery. Small AGMs of like 6, 7 ah are only around $20-30. The ones about twice that size $40-50. I wonder if it is because of the dedicated post design that they get expensive? (I would find a way around that!). Starter batteries still need to be lead acid because lead acid can take continuous charging, and lithium cannot and that can really mess things up, but I wonder if the auxillary battery can be LifPo4. Probably not if it is subject to the same charging pressures as the starter battery. But being auxillary might have if buffered a bit. If the lithium shuts down the lead acid starter still works. Is it possible?
