A Batteries 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 Batteries also provides energy to light and other element of car .healthy car Batteries will perform the functions it is designed to perform. The load on the Batteries should never be greater than the (13v) power supplied by the alternator.
For choosing a car Batteries you should take into account following point What are the size and dimension of your main car Batteries? 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
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 Batteries when this occurs, it might create an ignition source that could cause the Batteries to explode. It's extremely important to remove the ground source first
You need to make sure they're fresh and damage-free. Make sure that the Batteries 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 Batteries casing for a special label or decal. You'll find the month and year that the Batteries 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.
"CCA" stands for "Cold Cranking Amperes". This is a rating used by the Batteries industry to define the Batteries’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 Batteries Council International defines CCA as "the discharge load in amperes which a new, fully-charged Batteries at 0ºF can deliver for 30 seconds and maintain a voltage of 1.20 volts per cell or higher."
"CA" stands for "Cranking Amps". According to the BCI, this is "the discharge load in amperes which a new, fully-charged Batteries 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 Batteries may be misleading, since it can be up to 30% higher than its CCA rating. The Batteries Council International "CA" stands for "Cranking Amps". According to the BCI, this is "the discharge load in amperes which a new, fully-charged Batteries 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 Batteries may be misleading, since it can be up to 30% higher than its CCA rating. The Batteries Council International requires that a Batteries carrying a statement of its CA performance must also carry a statement of CCA capacity.
Reserve Capacity, (RC) is a Batteries industry rating, In order for starting current to flow, the Batteries voltage must be at or above a minimum voltage level and the electrical circuit must be complete. As current is withdrawn, the Batteries’s voltage lowers. Normally, the engine starts and runs without sustained or repeated cranks
Reserve capacity is the number of minutes a Batteries can maintain a useful voltage under a 25 ampere discharge. The higher the minute rating, the greater the Batteries'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.
Extreme heat causes the corrosion and chemical processes inside the Batteries to accelerate. Both of these processes shorten the life of the Batteries. In addition, high heat causes the Batteries’s fluid to evaporate more rapidly.
If your start Batteries your motor is experiencing slow or interrupted turnover; your instrument panel indicates Batteries discharge for extended periods after the engine is running; your Batteries seems to lose power quickly in cold or extended starts; your headlights dim at idle.
It's easy to jump start your car if you have a dead Batteries. 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.
