Time to replace the car battery.


Remember the battery helps your car to start whenever you want to use your car
and it provides power to the car accessories and electronic parts. Furthermore, some of the electronic parts use power from
the battery whether the car is on or off. The consistent supply is only dependable if the battery is in good health.
Just like you have other car, components checked and replaced if the need be, do not overlook the battery. Regular test
will let you know when you need to install a new one. Once again, make sure you go for something that will not disappoint you.
If you are not sure where to start looking, then you can try reading some reviews first. Let us face it; you will eventually
have to replace your car battery. That means you should learn and benefit from the information shared online and make a sound
decision. Car batteries vary in price and can range from height to location. Most of the batteries will disappoint especially after the 
first 3 to 4 years. Although reviews are biased on the brand depending on other facts, you will be able to settle for a battery.

Battery frequantly asked question

 Does battery perform its functions?
A battery is a device that converts chemical energy into electrical energy. Batteries have two electrodes the positive electrodes and negative electrodes. The voltage runs through a chemical called an electrolyte. The electrical energy used by the car system. The car battery also provides energy to light and other element of car .healthy car battery will perform the functions it is designed to perform. The load on the battery should never be greater than the (13v) power supplied by the alternator.
Choosing a car battery?
For choosing a car battery you should take into account following point What are the size and dimension of your main car battery? What are the cold Cranking Amps needs to power the particular Vehicle? Each Automobile batteries has its warranty period choose what suites best for your car
When you are changing battery or cleaning the terminals, is it crucial to remove the ground wire first?
First of all you should check the type of grounding system the vehicle has. . If you remove the positive connector first in a negative ground system, you risk the chance of creating a spark. That could happen if the metal tool you're using to remove the positive terminal connector comes in contact with any piece of metal on the car. If you are working near the battery when this occurs, it might create an ignition source that could cause the battery to explode. It's extremely important to remove the ground source first
How can you know that your battery is brand new?
You need to make sure they're fresh and damage-free. Make sure that the battery you buy is produced by a known and respected manufacturer, and that it's fully charged and ready to start your car. Look on the side of a battery casing for a special label or decal. You'll find the month and year that the battery was shipped from the manufacturer's plant. The letters 'A' through 'M' represent months of the year. For example, 'A' is January and 'M' is December. The letter 'I' is not used. The numbers 1 through 9 denotes the year of manufacture. Therefore, if the sticker on your batter reads L4, you know that it was manufactured in November 2004.
What does CCA mean?
"CCA" stands for "Cold Cranking Amperes". This is a rating used by the battery industry to define the battery’s ability to start (crank) an engine under low- temperature conditions. Cranking an engine requires a large amount of current for a short time span. The Battery Council International defines CCA as "the discharge load in amperes which a new, fully-charged battery at 0ºF can deliver for 30 seconds and maintain a voltage of 1.20 volts per cell or higher."
What does "CA" stand for?
"CA" stands for "Cranking Amps". According to the BCI, this is "the discharge load in amperes which a new, fully-charged battery at 32ºF can continuously deliver for 30 seconds while maintaining a terminal voltage equal to or higher than 1.20 volts per cell." The CA rating of a battery may be misleading, since it can be up to 30% higher than its CCA rating. The Battery Council International requires that a battery carrying a statement of its CA performance must also carry a statement of CCA capacity. 
How important is reserve capacity?
Reserve Capacity, (RC) is a battery industry rating, In order for starting current to flow, the battery voltage must be at or above a minimum voltage level and the electrical circuit must be complete. As current is withdrawn, the battery’s voltage lowers. Normally, the engine starts and runs without sustained or repeated cranks
Reserve capacity is the number of minutes a battery can maintain a useful voltage under a 25 ampere discharge. The higher the minute rating, the greater the battery's ability to run lights, pumps, inverters, and electronics for a longer period before recharging is necessary. The 25 Amp. Reserve Capacity Rating is more realistic than Amp-Hour or CCA as a measurement of capacity for deep cycle service.
What can excessive heat do to a battery?
Extreme heat causes the corrosion and chemical processes inside the battery to accelerate. Both of these processes shorten the life of the battery. In addition, high heat causes the battery’s fluid to evaporate more rapidly.
When my car won't start, how do I know for sure if my battery really needs to be replaced?
If your start battery your motor is experiencing slow or interrupted turnover; your instrument panel indicates battery discharge for extended periods after the engine is running; your battery seems to lose power quickly in cold or extended starts; your headlights dim at idle.
How do I safely jumpstart my battery?
It's easy to jump start your car if you have a dead battery. Batteries go dead for all sorts of reasons, but usually it's our fault. This is a good thing, because that means a simple jump-start will get you back on the road with no permanent damage. What You'll Need Another car, running , Jumper cables , Safety glasses , Wire brush (optional for cleaning connections)
You'll need to park the running car next to the dead car in such a way that the jumper cables can reach both batteries. If you aren't sure where the batteries are under each hood, take a peek before you park.
