If jumping from another vehicle, shut that vehicle off and just use its battery.

One Cardinal Rule: One of the Negative Connectors on the jumper cables is ALWAYS the last one connected and the first one DISCONNECTED when done. This prevents sparks and surges.

Same with Battery Terminals or a Charger... the Negative is always last on and first off.

 

would you happen to know what happens if i jumped my car often tho? it's too late now because i didnt know about this and i jumped my car plenty of times using my durango.

 

You are probably OK. If you have a specific issue or concern, let us know...

 

Why would jumping affect anything? I don't get this topic.

You're just connecting another battery in parallel and starting the car. You're not exceeding the voltage of the system.

 

Potential surges & spikes.

That's why the neg is always the last on & the first off.

 

Why not just replace the battery rather than jump starting it ?

 

Because the battery may be fine; it just may not be getting charged properly due to a failing/failed alternator for example

 

Delete.

 

Why would I delete… if I need some input?

 

I helped a motorist the other day with cables. No ill effects. Be careful. Last on and first off Black as described. Protect fender too. The underhood jump box with ground doo dad makes it easy.

 

I have never had an issue jumpstarting a car but I only use it for emergencies. I always try with the other car off first if the battery I’m jumping is smaller.
This has nothing to do with voltage by the way. 12V systems have to be stable up to 18-19V. The current is what you gets you

 

Okay............ what does your manual say? Mine says it ok and explains it on two pages. I would believe that over "a couple of posts" here.

 

Yes agreed. But it doesn’t hurt to ask. Idk why people are being so negative about this post. I’m just trying to be safe. If you guys think it’s a dumb question then just don’t respond. I’m here to seek help not so get told what topics are dumb

 

My SOP is to use jump starting as a last resort. So far I have not had to have a car jump started in as long as I can remember.

I hate to say it but I am loathe to offer my car to provide a jump start. I don't carry jumper cables.

The risk is the cables can be connected wrong (reversed) or while connected correctly can result in a voltage surge/spike.

If you have to jump start your car once that's bad enough. If you have to jump start it more than once you need to get the reason why it needs to be jump started sorted out.

I can offer my experience with my Hellcat is it did not like to sit unused for any real length of time. It never sat so long to require a jump start but I made it a point to use the car often enough this kept the battery healthy. (Connecting a battery charger/maintainer was not an option.)

If you don't or can't use your car often enough to keep the battery topped up you need a battery charger/maintainer.

 

Thank you for your kind reply. I actually think that it is an alternator issue. I’m going to take it to the dealer to get a diagnostic

 

This is what I've used for the last 7 years. Never had issues. Portable, don't need another car. I carry it in my trunk and recharge it once a year just to keep it at maximum charge.

Mostly everyone here must think I’m dumb or something. I’m literally asking this because the battery is brand new and the car won’t start. You can tell me “oh why jump start instead of getting a new battery” well no shit.. yea I think that’s what everyone would do… but if it’s a bad battery. I took my new batter back to autozone to get it tested because the car ran fine for 2 months and now it won’t crank over. Which is why I have been jumping it. Hence this topic.

 

A battery can fail at any time regardless of age. It can be fine & fail in the next moment. That includes right after Autozone said it is fine.

Might be best to get your HC to the dealer...

 

Cars are a lil different today then in the 70’s

I have never personally had a problem but I no longer jump anyone and if I’m messin w something that has a dead battery I remove cables before I put a charger on it

Do whatever ya want but I know a few people that have created problems

Thank you. This is why I created this topic.

 

Didn’t I reply like 20 posts ago to meter out your battery with the alternator and car on? Jeez. Should be over 14v and you can see if it’s charging.

you going to get it towed to a dealer without checking the alternator?

 

Since it wouldnt start i had to tow it somewhere.. there was no point of towing it to Autozone for them to test the alternator so i towed it straight to the dealership.. it has a recall any way so i rather get both done at once

 

The cars, and manuals, are "usually" pretty good from the factory. Us, and the technicians, mess them up, right? The manuals are written in a very basic way and if that is too technical, maybe just take it to the dealer (my sisters should NEVER attempt anything and just take it to the dealer). I will never believe a post here over the manual since most never read the manual to begin with.

 

Im posting to update you all that thankfully neither the alternator or starter were the issue. I got feedback from the dealership and it looks like who ever installed my lights didnt do a good job. thank you all for your inputs and for trying to help and give me all of your advices.

 

Find an interstate battery location and have them test it (it's free). They do a much more comprehensive test than autozone, and can determine if it's your battery or alternator.

 

thank you! i actually no longer need to do that.. i just got an email from the dealership stating that it was a wire cause the issue
