is it true that your battery gets worn down when you use jumper cables?
something told me that if you help someone else jump their car with cables, it hurts the life of your battery.
is this true? |
RE: is it true that your battery gets worn down when you use jumper cables?
I don't think so. I have the engine running when I jump-start someone, so it's not using the battery so much as using the alternator.
It's safest to jump-start someone with a smaller car than yours. But I've broken that rule many times & usually my batteries last rather long. Several things hurt battery life... - Letting the water level get low (uncovering plates is BAD) - Excessive high-temperature (idling) - Deep discharges (deep enough so it won't start) - Too-rapid charging - Overcharging (like if your voltage-regulator fails) |

Any use of the battery wears it. Jumping another car uses about what it would to start your own car. So the statements is technically correct but insignificant.
I would recommend turning off your car when jumping another car in case the dead car has serious electrical issues (potentially damaging your alternator circuitry) |
RE: is it true that your battery gets worn down when you use jumper cables?
well the concept of the damage mainly comes from the fact that you're creating a fairly-closed circuit between the two cars/batteries, which is NEVER good for a power source...
it's mostly understood to damage the weaker of the two batteries though, and definitely your alternator. i try to jump as little as possible, mostly cuz I don't want to risk anything... they sell those little jumpers for like 20 bucks i think for emergency packs. |

yeah, my brother bought one from a toyota dealership.
it's great!, but extra weight in the car |

I have heard that jumping can hurt alarm systems.
Any truth to that? |

I would never try to jump someone else's car with my car turned off. Likely you will drain your own battery immediately, then you will have 2 dead cars instead of one.
I don't think it will hurt your battery. When i drove my 91 Mustang I jumped people off all the time. of course, that is a much bigger engine and I doubt I ever jumped anyone off that had an engine any larger than mine, but the same concept applies. If your car is running and the alternator is functioning properly, the alternator will be constantly charging your battery. therefore i don't see any reason jumping someone else off would shorten your battery life. I buy batteries that have lifetime warranties anyway. So if it ever goes dead, it is replaced for free. |

Duralast at AutoZone is cheap and they give a lifetime warranty. Optima=waste of money IMO
