PANASONIC CAR BATTERY

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 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.

When I am replacing 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.

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 Ampere Hour Capacity?

Ampere Hour Capacity at 5 Hour rate is the amount of electricity that a battery will deliver during 5 hours after the battery is fully charged and electrolyte temperature remain at 25°C until the voltage falls to 10.50 V.

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. Some of the troubleshooting you can do when your car won’t start:

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.
Is Maintenance Free (MF) battery called Dry Cell battery?

No. The "maintenance-free" battery, similar in design to its conventional counterparts that need to refill with distilled water from time to time to maintain the fluid level. It is actually just a heavier-duty version of the same arrangement. Many of the components in the maintenance-free battery have thicker construction. Different, more durable materials are typically used.

For example, the plate grids often contain calcium, cadmium or strontium, to reduce gassing (which causes water loss) and self-discharge. This design is called a lead-calcium battery. The heavier-duty parts ensure that fluid loss is kept to a minimum and that components have a much longer life, making it a closed system.

The advantages of maintenance-free battery are: less preventative maintenance, theoretically longer life, faster recharging, greater overcharge resistance, reduced terminal corrosion and longer shelf life.

WHAT IS ENGINE COOLANT?

An engine coolant is an important fluid for the car. It performs two primary functions in the car which is prevent it from over-heating during hot weather and prevent the car engine failing during extreme cold weather. It’s mainly made up by mixing ethylene glycol and water to the ration 50% of ethylene glycol and 50% of distilled water. Ethylene glycol is odorless, colorless and syrup liquid with a sweet taste. It is also toxic which can cause ingestion to human and animal.

WHAT IS THE FUNCTION OF A RADIATOR?

The radiator is a cooling system to protect against damage and keep the engine operating within the suitable or correct temperature range. The radiator also designed to protect an engine from massive heat and also to lower the temperature with the help of the coolant and cooling air.

COOLANT VS WATER

High Temperatures

  • The coolant can takes more heat than water which means that coolant can protect the car at higher temperature and also longer spans of time.

Cold Temperatures

  • Water will freeze during the winter and it will damage the engine, radiator and water pump. That’s why it needs to drain out during the winter. Unlike the water, coolant doesn’t freeze and yet still work well during cold temperatures.

Corrosion

  • Coolant contains chemical ingredients to prevent corrosion. Water contain such as minerals and additives which can cause severe corrosion.
What does engine coolant do?

Helps to transfer heat from the engine to the radiator to the air.

How often should the engine coolant be flushed?

The cooling system should be flushed out at least once every two years or 40,000 km to prevent the rust.

What causes my car engine to overheat?

The engine overheat may be due to the low oil levels, a leaking head gasket, coolant leaks, faulty water pump and also failing thermostat.

What may be some of the consequences of using the wrong coolant?

Reduced corrosion protection of cooling system components, incompatibility with engine gasket materials, corrosive attack of aluminum components, cylinder wall cavitation and engine block damage in diesel engines and potential water pump issues.

WHAT IS BRAKE FLUID?

Brake fluid is a type of hydraulic fluid and important part of the brake system. Brake systems need to be able to function through all types of conditions. All the brake fluids must meet the standard of Department of Transportation (DOT). They are DOT 3, DOT 4 and DOT 5.1. Each brake fluid type will have formulation or chemical differences and different and wet boiling points. DOT 3, DOT 4 and DOT 5.1 is a polyethylene glycol-based fluid (contrasted with DOT 5, which is silicone based). Brake fluid must maintain a very high boiling point. Exposure to air will cause the fluid to absorb moisture which will lower the boiling point to reduce vapor locking phenomenal. Brake fluid is hygroscopic, which means, it absorbs water over time.

How many types of brake fluids?

DOT 3

Most of the domestic cars and light trucks are using the DOT 3 brake fluid. This poly glycol base product has a dry boiling point (ERBP) 205°C and wet boiling point (Wet ERBP) is 140°C minimum. Dot 3 brake fluid can safely be mixed with DOT 4 and DOT 5.1 brake fluids. The boiling point if this brake fluid is reduced as it absorbs moisture which reduces its performance and making the brake pedal spongy.

DOT 4

This brake fluid is also a poly glycol base product. It is used in larger cars in high-altitude, high-speed braking situations, ABS systems and full-sized trucks. The dry boiling point (ERBP) is 230°C minimum and wet boiling point (Wet ERBP) is 155°C minimum. Same as DOT 3, DOT 4 brake fluid also will absorb moisture out of the atmosphere and damages the vehicle’s paint.

DOT 5

DOT 5 brake fluid is not suitable for ABS systems and mostly used in old, antique and collector cars. This brake fluid is based upon silicone. The dry boiling point (ERBP) is 260°C minimum and wet boiling point is (Wet ERBP) 180°C. This brake fluid cannot mix with DOT 3, DOT 4 and DOT 5.1. This type of brake fluid does not absorb water and will not damage the paint on the vehicle. However, it does absorb air and make the brake pedal feel soft and spongy.

DOT 5.1

This brake fluid also based upon poly glycol. And has a higher boiling point compared to DOT 3 and DOT 4 which is the dry boiling point (ERBP) is 260°C minimum and wet boiling point (Wet ERBP) is 180°C minimum. It is used in heavy-duty vehicles, delivery trucks, towing vehicles and race cars. It can be mixed with DOT 3 and DOT 4 without damaging the brake system. Same as DOT 3 and DOT 4, DOT 5.1 also can damage the vehicle’s paint and absorb moisture out of the atmosphere.

What is the key functions of brake fluid?
  • Acts as hydraulic fluid.
  • Minimizes Vapor Lock.
  • Provides Rubber Protection.
  • Acts as Anti Rust and corrosion agent.
  • Maintains fluidity under different weather.
  • Why change the brake fluid?

    Brake fluid is hydroscopic fluid and it will absorb moisture from the air which degrades its performance. This moisture causes rusting and pitting of internal parts, which leads to unnecessary replacement costs. And also leads to brake failure.

    When should I replace my brake fluid?

    Most vehicle and brake fluid manufacturers recommend the fluid should be changed every 2 years regardless of how many miles a vehicle uses.

    Should I have a brake fluid flush done?

    New brake fluid is both clean and clear. The dirt and contamination can accumulates in the fluid and wear on all of your hydraulic brake parts, particularly your seals and causing a lots of internal damage. The repair cost could be very costly.

    Is power steering fluid same as brake fluid?

    Power steering fluid is completely different from brake fluid and NOT interchangeable. Power steering fluid has high boiling point and low freezing point. And brake fluid has very low compressibility and high boiling point.

How do brake pads work?

The squeezing action of a disk brake pad against a disk brake rotor is made possible by hydraulic brake fluid. Instead of using a cable to manually squeeze the brake pad against the rotor, hydraulic brake fluid is used to supply the squeezing force. Brake fluid lines route the hydraulic brake fluid into each disk brake caliper, where the pressurized brake fluid pushes against the brake pads, causing them to move, or squeeze, against the disk brake rotor.

What is the average life span of brake pads?

Depends on what type of pad (organic or semi-metallic) and driving habits.

Why is my brake making a grinding noise?

Excessive usage of brake pads leads to their wearing down.

How often should brake pads be changed?

Check the pad wear by you by two ways.

  • First is by visually. Check the depth of the pad whether is less than ¼ inch and if yes, please replace it.
  • Second is by ear. When braking, you heard a screeching sound like scraping on metal.
Why used drilled and slotted discs?

Clean, refresh the pad surface, lightened the disc and improved ventilation increases the disc’s ability to shed heat.

Why my brakes feel like ‘spongy’ when I press it?

Air trapped in brake lines due to leaks or replacement of parts.
