What is a flooded battery? In the factory, batteries are assembled using unformed plates and then filled with diluted sulfuric acid before being charged. This process allows the chemical reaction to take place, making the battery ready for use.
What is a dry battery? Unlike flooded batteries, dry batteries have their positive and negative plates already formed and charged in an acid tank. These dry, pre-charged plates are then placed into the battery case. Once the battery is activated by adding diluted sulfuric acid, it can provide a steady current for various applications.
What makes up a battery? A standard lead-acid battery consists of several key components: a polypropylene (PP) battery case, a cover with a water fill cap, positive and negative plates, separator plates, lead connectors, and diluted sulfuric acid. Each part plays a crucial role in the battery's performance and longevity.
What is reserve capacity? Reserve capacity refers to the amount of time a fully charged battery can supply power at 25 amps while maintaining a voltage of at least 1.75 volts per cell. This is especially important in situations where the vehicle’s charging system fails, such as during a breakdown or engine stall.
What is CCA? CCA stands for Cold Cranking Amps, which measures the battery’s ability to start an engine in cold conditions. According to the Battery Council International (BCI), CCA is defined as the amount of current a new, fully charged battery can deliver for 30 seconds at 0°F (-17.8°C) while maintaining a voltage of at least 1.2 volts per cell.
How to choose the right battery for your car? The best approach is to consult your vehicle’s owner’s manual for the recommended battery size and specifications. If that’s not available, refer to the battery application guide, which provides information on model, year, and required parameters. Always look for the correct group size and minimum CCA rating.
What should you keep in mind when charging a battery? Always handle batteries with care, as they contain corrosive sulfuric acid and can release explosive gases. Here are some essential safety tips:
1. Read the charger’s manual carefully before use.
2. Charge in a well-ventilated area.
3. Ensure all connections are secure.
4. Connect the red cable to the positive terminal and the black cable to the negative terminal.
5. Turn off the charger before connecting it to the battery to avoid sparks.
6. Do not charge damaged or frozen batteries.
7. Avoid overcharging or leaving the battery connected for too long.
How to maintain your battery? Regular maintenance helps extend its life. Clean the terminals and water cap if necessary. A clogged water cap can cause pressure buildup and even explosions. Check the fluid level in each cell and top it up with distilled or deionized water only. Avoid overfilling, as spills can damage your car’s paint and metal parts.
When should you replace your battery? Signs that your battery may need replacement include:
1. Slower cranking when starting the engine.
2. The dashboard warning light stays on after the engine starts.
3. Reduced performance in cold weather or extended cranking times.
4. Dim headlights when the engine is idling.
If you notice any of these signs, it’s wise to perform a load test or consider replacing the battery.
How long does a battery last? The lifespan varies depending on the battery type, driving habits, and climate. On average, a standard lead-acid battery lasts between 18 to 30 months. Frequent short trips, extreme temperatures, and improper charging can shorten its life.
How to prevent your new battery from dying? To keep your battery in good condition:
1. Turn off all lights, radio, and accessories when the engine is off.
2. Check the alternator and belt regularly—worn belts can reduce charging efficiency.
3. Inspect the electrical system for shorts or faults that could drain the battery.
