Just another “I don’t like your answers, so I’ll keep asking until I get one that I like” post. To the OP, use your jump pack without disconnecting the battery. If the alternator is charging and the battery still goes dead replace the battery. If the alternator isn’t charging replace the alt. this is not rocket science. ---

Slow day. I have no idea what brand I have but it’s in the trunk and never used it. Both of my batteries are new or near new. If one was discharged I would put the battery charger on it and evaluate whether to replace it. But everyone is free to do what they want as long as they aren’t being paid for their actions. Bye. ---

It is not that simple, the vehicles charging system operates at a low voltage, it would take 12 hours for the alternator to recharge the battery. To draw that conclusion in haste results in many unnecessary battery and alternator replacements. ---

> [@Nedved](#): > > If the car battery is dead, can you disconnect it and use your jump starter in its place? Didn’t anyone.understand the question? I think that we all understood. You don’t disconnect the battery to use the jump starter. You put the jump starter on the still-connected cables, and then remove the jump starter once it starts. Why do you think you’d need to disconnect the negative cable to use the jump starter? That’s not how jump starting works no matter what. And additionally… - the battery needs to remain in the circuit to absorb voltage irregularities from the alternator. Can the alternator run the stuff in the car without the battery in the circuit? Sure! Until you fry a computer. - if the battery is “ok” but has just lost charge for some reason, then - if it’s not an emergency - it should go onto a charger. Alternators maintain a battery charge. Asking them to be battery chargers is abuse of the alternator. - if the battery is just “dead” - meaning it won’t accept and/or hold a charge, then you get a new battery. You make sure it is charged, and go on your way. So, to reiterate - I think that everyone “understood the question.” But it’s still a mystery as you why you’d want to try to run a car from a jump pack - except, perhaps, to limp it to a shop or auto parts store. ---

Thanks I’m guessing that was a sedan, not that hatchback? Was that equipped with all the bells and whistles? ---

No matter what? If the battery is shorted? Okay. Let’s say someone has stolen your battery, will your jumpstart battery start and keep the engine running? ---

> [@Nedved](#): > > No matter what? If the battery is shorted? > Okay. Let’s say someone has stolen your battery, will your jumpstart battery start and keep the engine running? Hi Nedved: This is about picking between your worst options. If your current battery is shorted and you leave it installed, then after you jump start the car, your alternator (and battery) could easily overheat, resulting in a fried alternator. If you remove the battery from a running car, as Cigroller noted, there won’t be anything there to absorb the normal voltage spikes that an alternator charging system produces. Without the battery being installed to act as a capacitor to absorb those voltage spikes, you run a very high risk of blowing some electronic circuitry in the car. As Nevada noted, the module on the jump starter cables will internally disconnect after the engine starts. This is to prevent alternator power from damaging the lithium-ion battery. That essentially means your car is running without any battery connected, subjecting you to the risks noted above. I used to run cars without batteries connected back in the 70s. They all ran fine most of the time. I would definitely not do it in today’s cars with the electronics being used. ---

Now you are asking a different question. You original question asked > [@Nedved](#): > > lithium jump starter battery will the car run on that battery and be recharged by the car when it is running? The answer to that question was **no**. Now changed to a “what if” question. Based on Rainflurry’s comment, I give this answer: Maybe. My question to you, why? If battery was stolen, just replace it. But then a new question for you, how did the thieves access the battery compartment? ---

Sounds like trying to split hairs now… If I comment about someone stealing the battery out of a Corvette, it will probably get flagged… lol ---

> [@davesmopar](#): > > If I comment about someone stealing the battery out of a Corvette, it will probably get flagged As well it should! 😀 Adulterated excerpt from the movie Unforgiven: _Corvette Bob:_ The Corvette is akin to royalty. A majesty that precludes the likelihood of adulteration or thievery. If you were to attempt to steal from a Corvette, your hands would shake as though palsied. _Barber:_ Oh I wouldn’t think of stealing from a Corvette sir. _Corvette Bob:_ Well that’s a wise policy, a wise policy. But if you did. I can assure you, if you did, that the sight of such automotive royalty would cause you to dismiss all thoughts of theft and you would stand… how shall I put it? In awe. Now, a run of the mill car… well I mean…why not? 🤣 ---

I got a free used jump pack battery. 12v 18ah. Sla. Been sitting in garage for 2 months. Was 12.7v yesterday. Might be good? I haven’t tried to use it yet. ---

> [@JoeMario](#): > > Without the battery being installed to act as a capacitor to absorb those voltage spikes, you run a very high risk of blowing some electronic circuitry in the car. Not something I approve of, but I observed coworkers doing this several times each week: They start the engine, remove the battery and take it to the parts department for exchange. Several minutes later install the new battery while the engine is still running. This is done so the vehicle owner doesn’t complain that the radio station list and the seat position memory has been erased. One in a thousand chance something will go wrong, I don’t do it, and it seems to scare a lot of people. ---

> [@cigroller](#): > > Out of curiosity, why don’t they just use one of those memory devices? Didn’t have one, didn’t want one, didn’t care… Amazed me that the manager didn’t stop that practice. Half of the vehicles arrive with dead batteries, many others require battery disconnect during repair, so memory reset is common with customer’s vehicles. ---

One in a thousand chance something will go wrong, I don’t do it, and it seems to scare a lot of people. Thanks Nevada for that update. I wonder if charging system spikes are less harsh than they were years ago. Or if the electronics in the vehicles are designed to withstand a given level of those spikes. I agree. It’s not something I would advocate doing. Thanks. ---

> [@Nevada\_545](#): > > Didn’t have one, didn’t want one, didn’t care… I’d expect the main reason is that configuring a memory saver to the battery takes a certain amount of the tech’s time, so the tech will make more money that day by not doing it. Works well as long as the customer doesn’t complain. Which apparently they mostly don’t, so skipping the memory saver a must work well enough for the tech to accept the risk of the possible adverse consequences to the customer’s car .
