1. How does a battery work?
 

A battery stores energy in chemical form that can be released on demand as electricity. This electrical power is used by the car??s 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.

 

2. What does "SLI battery" mean and how is the battery constructed?
 

An SLI battery is an automotive battery and stands for Start, Light and Ignition. Two substances dominate a standard SLI battery: lead and sulfuric acid. The positive electrode consists of lead-dioxide, the negative electrode is composed of finely distributed sponge lead. The sulfuric acid forms the electrolyte, ensuring the flow of ionic current between the battery's electrodes. The sulfuric acid's maximum conductivity is obtained at a gravimetric density of 1.28 kg/l. This is a typical acid density. In an SLI battery, positive and negative electrodes are alternately welded to electrode stacks and set into the battery housing. A separator is placed between them to electrically isolate the positive and negative electrodes from each other. Six of these series-connected electrode stacks form a 12V battery.

 

3. What should I consider when buying a SLI battery?
 

a) SIZE: What are the dimensions of your original battery? Please check it by yourself. 

b) POWER: What are the Cold Cranking Amps required to power your vehicle?. 

c) WARRANTY: SLI batteries are backed by a warranty package. Chose what is right for your vehicle's needs. 

 

4. What happens when an SLI battery is charged?
 

As soon as the engine starts running, the battery charging process is initiated by means of the alternator. The result of the recharging process is that the lead sulfate formed during the discharge process will again become lead dioxide, lead and sulfuric acid, thus restoring the necessary chemical energy to be converted into electrical energy in future use. The optimal charging voltage of the car's voltage regulator is 14.2V. If the regulator voltage is set too high, water will be electrolyzed. This lowers the electrolyte level over time. If the regulated voltage is set too low, the battery will not be charged properly, this also shortening its life span. 

5. Why is it important to remove the ground wire first before replacing my battery or cleaning the terminals?
 

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.

6. How can I tell if a battery is fresh? 
 

ou can usually find a date code on the top of the battery container giving you the month and year the battery was shipped out of our factory. 

7. 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 temperature. The rating is the number of amps a new, fully charged battery can deliver at 0oF(-18oC) 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.

8. What are CCA rates? 
 

This is a rating used to describe the discharge load in amperes which a new, fully charged battery at 32oF(0oC) 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.

 

9. 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 80oF(27oC) 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.

10. What can excessive heat 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.

 

11. 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. Check out other troubleshooting tips as below:

 

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 holddown or a lack of holddown 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 

 

12. How do I safely jump start my battery?
 

If the battery won't start your car, you usually refer to it as "dead," even though that's not technically correct. A car battery that's merely discharged - from leaving your headlights on or from a damaged alternator -- can be recharged to its full capacity. But a battery that's at the end of its service life can't be recharged enough to restore it to a useful power level. Then it truly is dead, and must be replaced.

If the battery is discharged but not dead you can jump-start it from another fully charged battery. About 30 minutes of driving should allow the alternator to charge the battery until you can get it to a service station for a full charge. However, if the alternator or another part of the electrical system in your car is damaged it won??t be possible to recharge your battery. 

Battery acid, or electrolyte, is a solution of sulfuric acid and water that can destroy clothing and burn the skin. Use extreme caution when handling electrolyte and keep an acid neutralizing solution? such as baking soda or household ammonia mixed with water? readily available. When handling battery acid:
 

* Always wear proper eye, face and hand protection. 
 

* If the electrolyte is splashed into an eye, immediately force the eye open and flood it with clean, cool water for at least 15 minutes. Get prompt medical attention. 
 

* If electrolyte is taken internally, drink large quantities of water or milk. DO NOT induce vomiting. Call a physician immediately. 
 

* Neutralize with baking soda any electrolyte that spills on a vehicle or in the work area. After neutralizing, rinse contaminated area clean with water. 
 

To prepare electrolyte of a desired specific gravity, always pour the concentrated acid slowly into the water; DO NOT pour water into the acid. Always stir the water while adding small amounts of acid. If noticeable heat develops, allow the solution to cool before continuing to add acid.
 

SAFE BOOSTER CABLE OPERATION
 

* When jump starting a vehicle, always wear proper eye protection and never lean over battery. 

* Inspect both batteries before connecting booster cables. Do not jump start a damaged battery. 

* Be sure vent caps are tight and level. 

* Make certain that the vehicles are not touching and both ignition switches are turned to the OFF position. 

* Refer to the vehicle owners' manual for other specific information. 

 

1. Connect positive (+) booster cable to positive (+) terminal of discharged battery. 

2. Connect other end of positive (+) cable to positive (+) terminal of assisting battery. 

3. Connect negative (-) cable to negative (-) terminal of assisting battery. 

4. MAKE FINAL CONNECTION OF NEGATIVE (-) CABLE TO ENGINE BLOCK OF STALLED VEHICLE, AWAY FROM BATTERY. 

Start vehicle and remove cables in REVERSE order of connections.
