- With a 70AH capacity and 710 cold cranking amps (CCA). Provides reliable performance and long service life, Up to 2 times the cycle life of conventional batteries. If your car's original battery is an AGM type, you must continue using an AGM battery, as your car will not accept a "downgrade" to a flooded battery. Nominal Voltage:12V. Charging Voltage:14.4~15.0V. Acceptable Charging Current:0~21A. Operating Temperature Range: -22°F~158°F.
- Heat / Cold Resistance: The materials used in the construction of AGM batteries (such as glass fiber mats and specialized separators) have better heat resistance. This allows AGM batteries to maintain their performance and capacity even in the hottest climates, They are also more resistant to extreme temperatures, making them ideal for hot or cold regions.
- Low Self-Discharge: AGM batteries have lower self-discharge rates compared to flooded batteries. Self-discharge refers to the loss of capacity that batteries experience over time when not in use. In hot climates, when the battery may need to be stored for extended periods or not frequently used, AGM batteries can better maintain charge, providing higher voltage output and easier engine start-up in any climate.
- Enhanced Safety: AGM batteries have a lower risk of acid leaks and spills compared to flooded batteries. This is because the acid is absorbed and held within the glass fiber mats, reducing the risk of corrosion or damage to surrounding components,this makes AGM batteries more durable and long-lasting, is also two to three times longer than flooded batteries. AGM batteries also have a lower risk of explosion and are safer to handle, making them ideal for high-performance vehicles.

Your Essential Guide to Choosing the Right Car Battery
Buying a new car battery can feel tricky. You need reliability to start your car every time. This guide breaks down what you need to know. We will cover key features, materials, quality factors, and what matters for your daily drive.
Key Features to Look For
Several features determine how well a battery works for your vehicle. Pay close attention to these three main points:
Cold Cranking Amps (CCA)
- CCA measures how much power the battery gives for 30 seconds at 0°F (-18°C).
- This number is very important, especially if you live where winters get cold.
- Check your owner’s manual to find the minimum CCA your car needs. Always aim for that number or higher.
Reserve Capacity (RC)
- RC tells you how long the battery can run essential accessories (like lights) if your alternator stops working.
- It is measured in minutes. Higher RC means more backup time.
Battery Size and Terminal Position
- Batteries come in specific physical sizes (Group Sizes). They must fit correctly in your car’s tray.
- Check where the positive (+) and negative (-) posts are located. Incorrect placement means cables might not reach.
Important Materials and Types
The inside material greatly affects the battery’s life and performance. Most modern car batteries use lead-acid technology, but the internal design varies.
Flooded Lead-Acid (SLA)
- This is the most common and usually the cheapest type.
- These batteries need occasional water top-ups (though many modern ones are “maintenance-free”).
- They work well in standard conditions.
Absorbed Glass Mat (AGM)
- AGM batteries use fiberglass mats to soak up the acid.
- They are sealed, spill-proof, and handle deep discharges better than standard batteries.
- AGM batteries cost more, but they last longer and are great for cars with many electronics or start-stop systems.
Factors That Improve or Reduce Quality
Quality isn’t just about the brand name. Several things affect how long your battery lasts.
Positive Quality Factors
- Thicker Plates: Thicker internal lead plates generally mean a longer lifespan and better resistance to vibration damage.
- Strong Casing: A durable, vibration-resistant plastic case protects the internal components from rough roads.
Negative Quality Factors
- Heat Exposure: High temperatures significantly shorten a battery’s life. Make sure your battery is not sitting directly on a hot engine block without proper shielding.
- Deep Cycling: Letting the battery drain completely (deep cycling) damages it quickly, especially standard batteries. Try not to leave lights on overnight.
User Experience and Use Cases
Your daily driving habits should guide your choice.
The Commuter
If you drive short distances often, your alternator might not fully recharge the battery between short trips. An AGM battery handles these partial charges better, preventing premature failure.
The Weekend Driver
If your car sits unused for weeks at a time, the battery naturally loses charge. A high-quality battery with low self-discharge rates will hold its charge better while parked.
The Cold Weather Warrior
Always prioritize high CCA ratings. A battery that struggles to meet the minimum CCA will strain your starter motor, leading to slow starts or no starts on frosty mornings.
10 Frequently Asked Questions (FAQ) About Car Batteries
Q: How long should a car battery last?
A: Most car batteries last between three to five years. Driving habits and climate play a big role in this lifespan.
Q: Can I use a battery with a lower CCA than recommended?
A: You can, but it is not suggested. If you live in a cold area, a lower CCA battery might fail to start your car during deep freezes.
Q: What does “maintenance-free” mean for a battery?
A: Maintenance-free batteries are sealed. You usually do not need to add distilled water to them during their normal life.
Q: What is the biggest killer of car batteries?
A: Heat is the biggest killer. Extreme heat speeds up the internal corrosion process inside the battery.
Q: Should I buy an AGM or a standard flooded battery?
A: If your car has complex electronics or a start-stop system, choose AGM for better performance. For older, simpler cars, a standard battery works fine.
Q: How can I tell if my battery is dying?
A: Slow engine cranking, dimming headlights when idling, or clicking noises when turning the key are common warning signs.
Q: Do I need to fully charge a new battery before installing it?
A: Yes. Even if it comes partially charged, you should always fully charge a new battery before putting it into your car for the best initial life cycle.
Q: What is the difference between starting power and running power?
A: Starting power is the massive burst needed to turn the engine over (CCA). Running power is the steady, lower draw needed to keep accessories going when the engine is off (RC).
Q: Does temperature affect CCA?
A: Yes. A battery’s output drops as the temperature drops. That is why you need a higher CCA rating for cold climates.
Q: Where should I dispose of my old car battery?
A: Do not throw old batteries in the trash. Most auto parts stores accept old batteries for recycling when you buy a new one.
