A battery check today can keep the tow truck away, says the Car Care Council, as it advises vehicle owners to have their battery tested and replaced if necessary this fall to avoid being stranded this winter.
Sooner or later all batteries have to be replaced, and excessive heat and overcharging are the two main reasons for shortened battery life.
Be sure the electrical system is charging at the correct rate; overcharging can damage a battery as quickly as undercharging.
If your battery is the type that needs to be topped off, check it regularly, especially in hot weather.
Always replace a battery with one that’s rated at least as high as the one originally specified. It can be one of the most annoying things to deal with, a car battery that goes dead at random times - you never know when it will leave you stranded.
Short-Term Driving:  Driving your car on short trips too often can contribute to a battery with a poor charge. Excessive Current Draw: There are devices in your car that will draw a small amount of current to stay on, things like your clock circuit and other items.

When properly programmed, the PCM knows when the throttle plate is fully closed and fully open. And you can pick up a battery powered jumper pack at any auto parts store or WalMart for under $50. This procedure keeps the PCM fully powered up and prevents it from losing all it “adaptive memory.” So you can start the engine and go without the PCM having to relearn all the values. A car battery is vital in supplying constant electricity flow into all electrical components in an automobile.
In the market today, there are two types of batteries on sale, namely wet cell and the dry cell.
Before proceeding to pop the hood, ensure that you have all the necessary tools to perform the job not forgetting correct battery size for your car type.


Ensure that there is no gas source, open spark or flame near you before proceeding to dismantle the car battery negative terminal first.
This simple DIY (do it yourself) tip on how to change car battery saves you tones of hassle at the workshop plus it is light on your wallet too. Heat causes battery fluid to evaporate, thus damaging the internal structure of the battery. A loose battery can be knocked around while driving, causing the life of the battery to be shortened dramatically.
Just like an AA cell, it has a positive terminal, a negative terminal and electrons flow from one terminal to the other. This is because the most taxing use of the battery in your vehicle is the initial engine starting phase (10-20 seconds) and when short trips are the norm, you never give it enough time to get fully charged. If it malfunctions and provides a charge that's too high or too low, then you can have a problem.
Normally this sort of thing won't kill your battery however, if you have an excessive current draw due to a wiring short circuit or some other kind of fault, then your battery may lose its charge before you get a chance to drive your car again. But if you disconnect the old battery without providing supplemental power to the PCM, it can “forget” those settings. You’ll need a jumper pack or an AC-DC power converter, and you’ll need a special OBDII cable. You’ll find in-depth information, technical service bulletins, code definitions and step-by-step tests, and easy-to-understand wiring diagrams, along with descriptions of how the systems work. The wet cell requires top up of sulfuric acid in order for it to perform normally and has a lifespan of three to five years, whereas the dry cell type is maintenance free.
A malfunctioning component in the charging system, usually the voltage regulator, allows too high of a charging rate, leading to slow death for a battery. Further, as corrosion accumulates on battery terminals it becomes an insulator, inhibiting current flow.
The primary function of a car battery is to start the engine by powering the starter motor and provide electric power to run the engine.
Some vehicles will relearn them on their own after a battery change, but others require a scan tool relearn procedure.


Dismantle the battery holder which usually sits on top to enable you to lift the battery out from the engine bay.
Colder temperatures increase the thickness of the engine oil, making the engine harder to turn over and the battery work harder, leading to harder starting.
If there are encrusted deposits on the battery, carefully clean the terminals with a wire brush dipped in baking soda and water. If you do need to disconnect the battery, remove the negative terminal first, then the positive. Frankly, in most cases you want a professional mechanic to troubleshoot this sort of thing, but here's a few things that will help you understand the situation. In addition to its primary function, it also provides electric power to the lights, horn, heater, and all the other electronic gadgets in the car. It's a build-up of lead sulfate crystals which can shorten the life of the battery and lengthen the amount of time needed to charge it. It’s wired into the PCM and the PCM controls a stepper or servo motor on the throttle body. So install a new car battery y using “old school” methods can actually cost you a tow and a minimum shop fee to put your vehicle through a relearn. An alternator is then used to restore lost charges in a battery when the engine is operational. If your battery is heavily sulfated and you don't drive your car a lot, as we discussed before, the battery may never get fully charged.
Ensure that the correct terminal is in place before proceeding to install the battery holder and tighten all nuts and bolts. The car should be able to come to life in one crank assuming all other engine parts are in good condition. And you need access to the latest technical service bulletins so you don’t waste time and money replacing parts that may misbehave due to a manufacturer’s software glitch.
