Notes on Car Battery Repair and Maintenance

Battery is an indispensable component on every car. It acts as a reserve power source, providing energy for the vehicle's operations when the engine is not started or when the generator is not working.

The battery is also the place to store electricity, supporting the operation of auxiliary equipment such as air conditioners, radios, and lighting systems. When the battery has problems or is damaged, how should it be repaired and maintained? Below are 5 Notes when repairing and maintaining car batteries. If you are also interested in this issue, do not hurry to skip the article below.

Pay attention to battery capacity

The first factor that you need to consider when repairing and maintaining your battery is its capacity, but you need to rely on old batteries to choose the right capacity.

Boot current parameters

Next, the factor that you need to consider is the starting current measurement, especially for diesel vehicles. New strong starting current can impact the ignition system to provide enough power to the engine.

Battery size

The selection of battery size is also a very important factor. No matter how high the battery capacity, the size that is not suitable for cars cannot be used. Therefore, you should be careful in choosing the size of the battery.

Choice of battery brand

When repairing and maintaining batteries, in case you need to replace new batteries, you need to pay attention to the brand of the product. When you know the brand of the battery has the right origin, or not. You will also be assured of the quality and product life.

Exchange old batteries for new ones

When you want to replace a new battery for your car, you can ask the dealer how to change the old one for a new one. Because for the most part, all facilities that maintain and repair batteries for cars will collect used batteries. Exchanging old batteries will save you money.

Some other notes

4 other notes to consider:

• You should not wear jewelry while near the battery because if you have short-circuit problems, high current flowing through can cause you serious burns.
• When removing the battery, cathode - very cool must always be removed first.
• When charging your car battery, you should leave it in a well ventilated place to limit explosion.
• Do not leave igniting sources of ignition or cigarettes near the battery while it is charging to avoid fire and explosion of electrolyte solution around.

FAQ – Frequently Asked Questions

1. Why do batteries fail and what are the signs that the battery needs to be replaced?

Battery can be damaged for many reasons such as:

• Lifespan: Batteries have an average lifespan of 3-5 years, after which performance will gradually decrease.
• Overcharging or deep discharging: Frequent overcharging or deep discharging will reduce the life of the battery.
• Electrical Problems: Electrical problems such as short circuits, overvoltage can damage the plates inside the battery.
• Environmental conditions: Temperatures that are too high or too low, high humidity also affect the battery life.

Signs that your battery needs to be replaced:

• Hard starting: Engine cranks slowly or won't start.
• Dim, weak headlights: Headlight light is weaker than normal.
• Unusual noise: When starting, there is a rattling noise coming from the battery area.
• Low Voltage: When measuring the battery voltage with a multimeter, the value is lower than the manufacturer's specified level.

2. How to check battery status?

There are many ways to check battery status:

• Visual inspection: Check for external signs such as bulging battery shell, electrolyte leakage, corroded terminals.
• Test with meter: Measure battery voltage at idle and when starting the engine.
• Using an electrolyte density meter: Measure the electrolyte density in each cell of the battery.
• Using a scanner: Some specialized scanners can accurately check the internal condition of the battery.

3. What is the average life of a battery?

The average life of a battery depends on many factors such as:

• Battery Type: AGM and GEL batteries typically have a longer life than wet batteries.
• Conditions of use: If used under harsh conditions, the service life will be reduced.
• Maintenance: Proper maintenance will help prolong the life of your battery.

On average, a car battery has a lifespan of 3-5 years.

4. What is the effect of temperature on the battery?

Temperature has a great influence on the battery:

• High temperature: Reduces battery life, increases self-discharge rate, dries out electrolyte.
• Low temperature: Reduces battery starting ability, increases internal resistance.

5. How much does it cost to maintain and replace the battery?

Battery maintenance and replacement costs depend on many factors such as:

• Battery type: AGM and GEL batteries are more expensive than wet batteries.
• Brand: Famous brands usually have higher prices.
• Capacity: The larger the capacity, the higher the price.
• Installation effort: Each type of vehicle has a different structure, the installation effort is also different.

6. What are the methods of charging batteries?

There are several methods of charging batteries:

• Normal charging: Charge with small current, long charging time, suitable for new batteries.
• Fast charging: Charge with large current, short charging time, not suitable for all types of batteries.
• Automatic charging: The charger automatically adjusts the charging current to suit each charging stage.

Note:

• Do not overcharge or deeply discharge the battery.
• Should use a dedicated charger to charge the battery.
• Do not leave the battery near heat sources or in damp places.
