How does a battery work؟
A batteries stores energy in chemical form that can be released on demand as electricity. This electrical power is used by the cars ignition system for cranking the engine. The car`s battery also may power the lights and other accessories. Should the alternator belt fail, the battery might also need to power the vehicle`s entire electrical system for a short period of time.
What should I consider when buying a battery؟
SIZE: What are the dimensions of your original battery? POWER: What are the Cold Cranking Amps required to power your vehicle? WARRANTY: Automotive batteries are backed by a warranty package. Chose what is right for your vehicle`s needs.
g my battery or cleaning the terminals, why is it important to remove the ground wire first؟
Before you start, always 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 I tell if a battery is fresh؟
You can usually find a small decal on the side of the battery container giving you the month and year the battery was shipped out of the plant. The letter corresponds with the month, starting with "A" for January, "B" for February, and so on. The number represents the year with "9" standing for 1999, "0" for 2000, and so on. A9, would be January, 1999. C0 would be March, 2000.( The letter "I" is skipped so the letter "M" would be December.)
What does CCA mean؟
Cold Cranking Amps is a rating used in the battery industry to define a battery`s ability to start an engine in cold temperatures. The rating is the number of amps a new, fully charged battery can deliver at 0° Farenheit for 30 seconds, while maintaining a voltage of at least 7.2 volts, for a 12 volt battery. The higher the CCA rating, the greater the starting power of the battery.
What are MCA or CA rates؟
This is a rating used to describe the discharge load in amperes which a new, fullycharged battery at 32 degrees F (0C), can continuously deliver for 30 seconds and maintain a terminal voltage equal or greater than 1.2 volts per cell. It is sometimes referred to as Marine Cranking Amps or Cranking Amps.
What is reserve capacity؟
Reserve Capacity, (RC) is a battery industry rating, defining a battery`s ability to power a vehicle with an inoperative alternator or fan belt. The rating is the number of minutes a battery at 80 degrees F can be discharged at 25 amps and maintain a voltage of 10.5 volts for a 12 volt battery. The higher the reserve rating, the longer your vehicle can operate should your alternator or fan belt fail.
What can excessive heat do to a battery؟
Hot temperatures will deteriorate a battery`s life quicker by evaporating the water from the electrolyte, and corroding and weakening the positive grids.
When my car won`t start, how do I know for sure if my battery really needs to be replaced؟
Many other problems can keep a car from starting, so you need to do some troubleshooting. Stores that sell batteries will often do battery testing free of charge, so that is a good first step.
How do I safely jump start my battery؟
When your car won`t start, you might jump to the conclusion that you have a dead battery. You should realize something else could be the culprit.
- Do you have a bad starter or solenoid?
Is your alternator bad?Your battery could also be discharged, which simply means it needs recharging. Check around to see what may be causing the battery to discharge.
- Has your car been sitting for a long time? If so, the battery may discharge by itself.
- Are there drains on your battery when your car is turned off? Check accessories including cell phones, radar detectors, GPS, TV, or computers. Even car alarms can impact your battery.
- Have you left your headlights, dome light, glove box light, or trunk light on for a long period of time? That can cause an excessive drain on your battery.
- Is it extremely hot or extremely cold? Both high and low temperatures can take their toll on the battery`s charge.
- Is there an electrical short anywhere in the vehicle?
- Have you modified your vehicle with air conditioning, power boosters, advertising signs, or additional radios?
The problem could also rest in something around your battery.
- Are your terminals or battery clamp corroded? If so, your battery won`'t charge properly.
- Is there a loose ground wire giving you an intermittent connection?
- Do you have a cross-threaded bolt on your side terminal? That could cause a loose connection.
- Is there a loose or worn belt? That can make your battery work too hard.
- Is your voltage regulator functioning? If not, your battery could overcharge or undercharge. You should also check your battery for related problems.
- Is your battery installed correctly? An improper hold down or a lack of hold down can cause excessive vibration and internal damage to the battery.
Do you have the right battery size? If your battery is too small for your vehicle, it may not function correctly
