Much has been said and written about car batteries and how to jump start a car with a dead one. The truth is, a lot of this info is either incomplete or wrong.
Sooner or later you will find oneself in a car having a dead battery. So please continue reading.
Here I will provide you with the right and up to dated method to jump-start a car safely. Obviously this is if you are stranded abroad. When you are at home the best thing to accomplish is use a charger, not a booster or cables. To start with I don't recommend jumping cables towards the motorist, second the most effective options are to employ a booster or just call (an expert mobile service) or make vehicle to an expert shop. If the battery is over the age of 3 years roughly, it could be bad. In the event you must use jumper cables then here' will show the proper way to do it. See the whole article because the info is over the same.
First good info about batteries.
I repair many vehicles with bad batteries. The reasons the battery went bad could be many, so after jumping an automobile you should seek specialist help. Here I will show you what can create a battery go bad, what to do to prevent it and activities in an emergency situation.
Why a battery goes bad:
o Bad alternator.
o Bad or loose serpentine belt or off or missing serpentine belt because of another bad component. o Excessive heat or cold.
o Age.
o Defective Part from factory. (Rare).
o Leaving the vehicle sitting a long time or driving the vehicle in short trips not
allowing battery to recharge.
o An excessive amount of drain, just like the battery is just too small for that demand. Or maybe
there are add-ons like monster stereo systems etc.
o Parasitic drain. Or simply leaving the lights something like that on.
o Dirty connector/terminals.
o Vibration. When there isn't any hold down.
o With all the wrong fluid to replenish it, like tap water instead of distilled water.
o Bad computer. The voltage regulator can there be in some cars.
o Physical damage. Car wreck, being dropped.
Taking care of your battery.
The best way to prevent battery failures is as simple as doing regular maintenance around the vehicle. When regular maintenance is done the battery should be one of the primary items checked. They need to clean terminals, fill up the fluid if possible using only sanitized water, do some tests onto it, and of course test the charging system etc. Every batteries will come across their maker ultimately. They can "die�hard" or die soft however they all die. The typical life of most batteries is all about 3 years, contrary to popular belief. Some top quality batteries lasts a bit longer. We have noticed a decline around the life of batteries lately. So if your battery is about that age, have it checked or simply change it to possess peace of mind specially in case you are making a long trip.
How to proceed if your battery is dead.
To pull up quickly when a battery is dead, first thing comes to mind usually is always to "jump" the car. Well I don't recommend this. To begin with this is a potentially dangerous action. (Achieving this can cause an outburst and injure you or actually kill you (items of plastic going off at very high speed can cut your throat), blind you, or deafen you). A very important thing will be to call someone to come and look at the car or go on it to a shop (there is a chance the alternator might be bad, so replacing or boosting battery may not solve your trouble). If you happen to have cables in your car then you have to find another car to enhance you. This is dangerous too, because in doing so you can damage very costly parts in both your and also the assistant vehicle. There is a change of connecting the cables wrong if you are not familiar with the process, if this happens it is possible to disable any of the two cars involved once and for all and incur in more expensive repairs. The best way to do this if you decide to boost the car has been a portable booster. Some possess a switch that may prevent you from causing sparks. A variety models have a device that will polarize the device automatically. So that it will be impossible for connecting it the wrong way. Some could be connected right in the lighter port, but this takes more hours because you have to let the booster charge the bad battery for some time, if you try to begin the car immediately you could blow the inline fuse or burn the cable.
Also once you get your car running, if you disconnect the assistant car and leave the car running to recharge your low battery this makes serious harm to the alternator. The alternator isn't designed to charge batteries that are too low or at zero volts but to maintain them charged. The proper way to do this is when using a portable booster to go away it connected to the car and so the alternator will charge both slowly rather than stress it self. The alternator has the ability to sense battery state of charge and also the system voltage demand. It's going to charge accordingly. If the battery is quite low it will charge continuously, hence straining it self and overheating. After Thirty minutes or so after that you can disconnect the booster and keep driving the automobile for some more hours to charge battery fully. Better yet just drive the vehicle to the nearest service place or call a mobile service when you are getting home. If you're driving at night or your automobile has day driving lights this will take a little longer. Obviously after having any problem with a low battery and getting the car running, the intelligent action to take is get a favorite tech to check on you system completely to get peace of mind.
Yet another thing that you need to know is this, sometimes there is a battery installed also it fails soon after (one or two days) why? Well there are different reasons, the battery could be defective (unusual), or there's an intermittent trouble with the charging system or a device that is putting a small drain when you turn the car off. New cars have numerous computers plus they use a little bit of energy following the car is switched off, but it is a really small amount plus it should not drain the battery in less than A few months approximately. Whether or not this does happens because one of the computers could be staying awake too long or has an intermittent short. Should this happen to you, do not get upset thinking they sold you a bad battery, or the mechanic is incompetent. The carr needs to be diagnosed again to determine what happened.
The proper way to jump-start a car.
This is the way I recommend to execute a battery jump with cables. This takes a little longer than what most publications recommend, but will be the safe method of doing it. I'm a professional mechanic with 28 many years of experience.
Before you even think about having your jumping cables out you ought to:
?First of all it won't hurt to see your owners manual, there you'll find lots of info pertaining the procedure. Like the location where the battery is "hidden" etc.
?Make certain both cars are close enough for cables to achieve with out cars touching.
?Inspect battery for warning signs of damage. A broken battery case isn't a good sign. Do not jump if case is cracked or else you see fluid leaking.
?Set the emergency brake on both cars and turn off both ignitions and some other accessories besides the flasher mentionened above previously.
?Keep one or more of the vehicles flashers on and every other safety device like flares etc displayed.
?Battery terminals ought to be free of dirt or corrosion. Use a minimum of water plus a wire brush to wash them.
?Ensure both cars are of the same voltage and polarity. Some cars are grounded in the positive rather than the negative although rare. Most cars in the road have 12 volts batteries. With the advent of hybrid vehicles I am going to strongly recommend you simply calling a specialist. Hybrid cars have quite high voltage batteries. 12 volts batteries won't harm you if you touch both terminals but hybrid use greater voltage. Also avoid connecting the cables backwards; very bad things can occur if you do.
?Wear a minimum of eye protection that features a face protector. Gloves will probably be nice too. Do not allow battery fluid to touch you, your clothes or perhaps the paint job.
?In snowy weather ensure the electrolyte is not frozen. (Make use of a flashlight etc to inspect, not a lighter).
?Use caution not to touch any moving area of the engine like belts, fans, etc while performing the task either using the cables or your clothes or jewelry etc.
?Now the cable part, (see illustration by the end of article) prior to deciding to connect some of the terminals make sure they are not touching one another to avoid any sparks. Batteries give off very explosive gasses that can kill you if they ignite. Also if the cables get hot be aware that they could be too thin or even the engine might be dragging for whatever reason. The starter is also bad (grounding it self). May also be you've cranked the car too much time. Check to make sure the clamps are attached properly. Let tem cool off a bit.
?Contrary like dome lights think about it after the cables are connected, the cables are connected correctly.
?The very first terminal to become connected as recommended is the positive one out of the donor's car then on the disabled car (both in the battery if at all possible).
?Then you connect the negative cable in the battery terminal from the donor's car and ensure you can access the engine at the disabled car for connecting the cable there.
?Once the cars finally starts, keep a minimum of the headlamps to aid in keeping any voltage spikes from damaging the delicate circuits inside the many modules on today's cars.
?(+) Is the positive terminal (usually red). (-) May be the negative terminal (usually black). This cable goes to the car chassis as well as the engine block in the battery.
?Disconnecting sequence will be the reversal of the connecting sequence
?Smoking just isn't recommended any time you are working near cars.
Much more about this.
Never attach batteries inside a series circuit way, you're going to get twice the voltage and blow a lot of things including computers. This may certainly damage your electrical system understandably.
Some cars with antitheft systems will activate it whenever the battery is low or disconnected. Again browse the owners manual for info on this and how to reset them. Every manufacturer use different systems.
When jumping an automobile you have to first charge the battery with the "donor" car not less than 5 minutes or even more if possible, then try, with all the cables disconnected to start out the car. When the car doesn't crank or cranks slowly then recharge more with donor car, then with cables connected attempt to crank the disabled car.
When selecting a set of jumper cables make sure you get a good quality set. The thicker the cable the better. Saving money here will prove an extremely bad choice. Cheap cables can overheat and in some cases burn or perhaps don't work if you use them (cheap construction around the clamps). Also don't get the shortest or the longest. The center will be best.
Never crank an automobile more than the recommended lapse within the owner's manual (usually a maximum of 10 seconds) in order to avoid damaging the starter. In the event the car cranks for very long periods with out starting then you may have more serious problems than simply electrical ones. Always wait a while before trying again in order to avoid damaging your starter or damaging the donor's battery.
If whenever you connect the final cable at the disabled car the thing is a lot of sparks make certain there isn't anything on, or perhaps the cables are connected properly (polarity), otherwise some sparks are normal since the disabled car's battery might be very low or just dead.
There are several top-of the line cables which include a foolproof device against connecting them wrong.
Every time the battery goes too low it gets weak. Not the same as deep cycle batteries on boats or RV's, car batteries aren't designed for this and definately will after a few discharges just quit altogether
Batteries was once better known as "accumulators" and you may guess why don't you? Yes they store electricity as well as the alternator's job would be to keep it charged not to charge it from 0 volt, that's the job of a charger.
An electric battery won't get damaged if kept in the concrete floor as opposed to on top of a piece of wood. Just how batteries are constructed today prevents this.
You don't have to go and spend a lot of money for a battery on the dealer, as well as towing costs. Any battery that meets the specification of your vehicle is going to do well if maintained properly. The trick here is to get the right battery, meaning the right capacity. Never use one that has lower than what is required. A little bigger is way better.
Some batteries have a little window with a green or black indicator to tell you if the battery is nice. Well this indicator is not very accurate for this, since it only measures the state of charge of only one of the battery's 6 cells. Another cell could be bad and also you could get a "green" indicator even tough the battery has only about 10 volts, which is not enough to correctly start a car. Some of the devices in your car might still work tough. The car will crank very slowly.
If by any chance acid gets in your eyes, do all you can to get it out pronto. The greater it stays there the higher the chance for cornea damage.
If you think a bad connection around the jumper cables, do not wiggle the connector while connected. Disconnect one on the disabled car first then wiggle the suspect ones then reconnect the rest. Remember you need to avoid making sparks. After with all the jumper cables wash all of them with water when possible and store them inside the bag they came in. This will avoid damage to your trunk in the acid that gets stuck towards the terminals. Always focus on a well-ventilated area.
The alternator. The heart of the system.
In case your alternator is bad, it was the cause of the dead battery to begin with; so jumping the battery won't enable you to get too far. Really should be fact you might not be able to drive a good mile more. You might end up in a neighborhood where you don't know anyone that will be too wiling to assist you.
If the battery or alternator or charging light was on prior to the battery died, then it's still on when you jump the vehicle then the charging system might have a problem. It will be a good idea to contact a professional. An alternator could possibly be malfunctioning even if you don't see a red light within your dash suggesting so.
If you're knowledgeable and wish to test your charging system having a voltmeter, consider this, some carmakers have systems that won't charge when the battery can be found to be full. This is accomplished to prevent overcharging also to increase miles per gallon (The drag on the engine is less) This also helps the longevity of the alternator.
Alternators usually are not designed to "charge" batteries (specially newer cars, they normally are weak in this area). Their job would be to keep a completely charged battery like that. When a battery goes down for any reason, the alternator has to work overtime to create it back to normal. The use of day driving lights is one of the reasons many alternators fail prematurely, the alternator works harder compared to a regular system. However they do offer an excellent safety measure. Also accessories not installed at the factory like monster stereos may also put a severe demand on the stock system not designed for such loads. There are some high amp alternators readily available for these cases. Also the use of multiple batteries helps. Consult a professional in this field for assistance.
Never disconnect a running car battery terminal to "test" the charging system. This is done long ago before cars started using computers. But today doing this will damage extremely expensive components. Therefore it may create sparks which could cause a surge. Believe me, many individuals still utilize this method to test the alternator, yes even people that "think" they know, like some airplane mechanics.
Starting a car with the cables connected and letting it run could damage systems in both car. Things like computers etc. I've fixed many vehicles with bad alternators and computers for this reason. That is why I would recommend charging the bad battery by letting the good car charge the bad one for around 10 minutes. Then you can disconnect the cables and begin the car with out damaging anything. There's a theory that running two cars using the cables connected can damage the alternators. I will up date this article with some details of this.
Push starting; it might not get you past an acceptable limit either.
An additional way to get a car running is by push starting it. This isn't recommended either. First, injury to the drive train can be done, (Expensive) particularly when done often. Second, as I mentioned before, when the car doesn't run since the battery is dead, the alternator will continue to work too hard to charge battery when you get it started. In the event the problem is the alternator, the automobile won't run too far at all since the battery is not getting any charge so it will be depleted soon. Push start should be done only in extreme emergency situations. As mentioned, be intelligent and call a professional.
I hope the info here was of help you. Remember no one is perfect. If you think there's a mistake or wish to add something for this article, you should contact me directly.
Thinking about the low cost of replacing battery with a new one and after reading this information I will be pretty sure you will decide not to risk performing a jump instead of replacing the battery. Unless of course, you're a professional and/or may have learned what I wrote here.
Today's cars are incredibly complex machines; it is best to leave what to the experts in terms of dealing with them. You will actually reduce expenses money (as well as your own life) this way by avoiding costly mistakes.
