FIVE SIGNS YOUR CAR BATTERY IS DEAD ( OR ABOUT TO DIE )
your vehicle's battery is like it's heart; without that battery, your vehicle wouldn't have power to start moving or do anything else.so it's important to understand at least a little bit about your battery, and to know the most common signs of a battery that needs to be replaced. ABOUT YOUR BATTERY The typical battery, in vehicle's made in 1952 and later, pump battery, a plastic cube containing sulfuric acid and lead, with two terminals coming out of the top or the side. This short guide should be reliable unless you have an aftermarket battery with special needs, such as a dry cell battery, or a hybrid like a Prius. HERE'S SOME GENERAL WISDOM ABOUT YOUR AVERAGE BATTERY. • Batteries normally have maximum life expectancy of two or three years, even if manufacturers say they will last for five years or more. If anyone sell you a "super long life" battery, keep your your receipt and get a warranty. Especially if you use the battery for a lot of accessories (things other than starting your car) it's unlikely to last as long as promised. • Optimally, you should replace your battery every two and half years or so -before you have problems. • Your battery needs some particular help doing its job starting your car: it needs help from your alternator,your starter, the solenoid, the battery terminals (which need to be clean and free from corrosion) , and its own cables (which need to be intact). Though as I argue below, the problem is very often just an old battery, I'll admit it can be something else. • An old battery, even if it doesn't show any obvious signs of being old, can affect your vehicle in negative ways that will slowly add up to a big repair bill. That's why I recommend replacing your battery before you have problems with it. • Your ordinary battery doesn't do so well in extremely cold weather, which may be why you have to pump the gas, or turn the key back to prime the fuel pump, or do a little dance to get the truck or car started on chilly mornings. MY MESSAGE: CHECK OUT THE BATTERY In my years as a mechanic and technician, one thing I have learned is that an old battery or loose battery cables can cause really big problems that make it appear that something complicated is wrong with your vehicle. Even experienced mechanics and DIY'er are sometimes stumped by a simple problem with a battery last its prime, until they realise they've riled out all other potential problems (and then some!). That's one of those moments you realise you could have saved yourself an hour of diagnostic and repair time, just by checking the battery and it's cables. SIGNS 1: ENGINE CRANKS BUT DOESN'T START If your engine cranks or turns over when you turn key, but it won't start, I say most likely culprit is your battery. it might something else, but 94% of time, its really your battery, even if the car is cranking fairly vigorously. Even if an ammeter (current-measuring device) says the battery is good, it can still be a few folks shy of what your vehicle needs to run efficiently. When you find yourself with a car that won't crank hard enough to start, you'll want to use jumper cables or a jump-starter box to get your vehicle running again. Once your car is running again, disconnect the canle , then let your car run for 30 minutes so that you alternator can charge up battery again. After that hour when you stop at home or a safe place, do a little test. After you turn the engine off, wait at least a minute, then start it again. wait another minutes or two, to make sure that you won't stranded with a dead battery at gas/petrol station or wherever you go next. Now, at the point, most batteries will have charged themselves up from the running of alternator and be fine for a day or two. DO NOT take that time for granted. Use it to hunt down a new battery and replace the old one BEFORE you end up stuck in the middle of nowhere. SIGNS 2: NO CRANK, NO START, NO LIGHTS This situation is pretty straightforward to diagnose, it's an even stronger indication that your battery is at faults, your battery powers all accessories and lights in your car, especially when the alternator is not running. So if your car just seems to be completely void of all signs of life, then your battery is the first thing you should be looking at. And aware that in this situation, where your vehicle doesn't even have the juice to work the lights or turn over the engine, it could be a combination problems involving your alternator was well as your battery. SIGNS 3: ONE DAY IT STARTS FINE, THE NEXT DAY IT WON'T If starting is an intermittent problem for you, it's a sign that either 1) your battery terminals are loose, broken, corroded, or calcified or 2) you have a parasitic draw ( your power is beimg drained by some gizmo that's on when supposed to be off, or by some wire that's touching something it shouldn't). Check out the battery cables first as they are usually the prime suspect and are easier to check yorself .Make sure the cables fit firmly and securely on the battery posts. There should be zero play in them; you shouldn't be able to wiggle them even an inch when they are tight. Also make sure that the cables going to the terminals are not frayed or falling apart;if they are, replace them as soon as possible. Parasitic draws from sources other than the battery cables are fairly common. Suspect a parasitic drawnif the car start right up if you drive it several days in a row, but then fails to start if you let it sit for a day. To investigate parasitic draw issues, see your favorite mechanic, and get ready to have fun with an ammeter or voltmeter, as these are the tools you'll need to check your alternator, accessories lights, fuses, radio, alarm, and all other components that might be draining your battery in secret. SIGNS 4: YOU'VE JUMPED IT A LOT I have a simple hard-and-come rule that I follow when it's comes to having to jump your battery. No matter what reason you having to jump the battery-the battery was old, or maybe the starter, fuel pump, or alternator were bad, or maybe you left your headlights on or your door ajar all night, or you ran out of gas-the rule is this: If you are to jump your vehicle more than three times in a single week, it's time to replace your battery. You could surprised, but even a fairly new battery can turn into a did really quickly if it has been jumped more than three times in a week. Using a jump box or jumper cables is hard on your battery. They work by figuratively "shocking" your battery. Now, you might think I'm crau about replacing the battery after such a low jump count, but hear me out. One of the most common things I see happening in relation to vehicle battery problems, is that the drivers or mechanic will assume that the because the battery wasn't old, or wasn't the specific culprit for the battery draining itself, they don't need to expand time or money getting a new battery. Then, when they try this this and that to diagnose the problem, they keep jumping the battery until finally the alternator and the starter go bad, leaving you with a need of new starter, alternator AND battery. save yourself the headache and replace the battery if you've had to jump the battery more than three times a week. You won't regret it. SIGNS 5:COLD CRACKING IS JARD WORK If you look at your battery, somewhere on it you should find a label starting a number for "cold cranking Amps" Those amps are responsible for giving your engine enough energy to get started the firs time of the day, generally referred to as "cold cranking" thus it's not surprising that an early sign that your battery is running out of life-a sign most people miss is that you are regularly putting extra energy into starting the vehicle. You know what I'm talking about. You get on your car, you tap the gas pedal, you turn the key a few times, and all you get for the first few minutes is lots of weak rotations of engine. After you've all but decided the car is going to make you late for work, suddenly starts up and sustains an idle. Now what I mean by "regularly" is having to do this more than three times a per week. That would be a signs that your battery is giving notice and getting ready to retire. But keep in mind that if it's really cold out, it's fairly normal for your vehicle to hang back and start only with difficulty. Not only is gas hard to vaporize and oil gooey when it's cold, but batteries put out half of their normal power when the temperature is 0°F (and only a third Of their power when it 32°F) so in the cold you may have to be patient. But if your car doesn't go back to a reliable "cold" crank when the weather warms upz you'll want to get a new battery within the next three months. One more possibility worth noting is that your battery was never big enough for your vehicle in the first place. Even a well-seasoned mechanic has gotten the wrong battery for specific vehicle, causing a wild - Goode chase investigation of a mysterious starting problem. Make sure you look up you car online, or ask in an auto part store, to find out what level of cold cranking Amps (CCA) and voltage your car needs to start and run properly. WHEN WILL YOU REPLACE YOUR BATTERY? I'm glad you've taken the time to read all the way through this article and started to considered when you will next replace your battery.
