Frequently Asked Questions (FAQs)
1. What is the main disadvantage of an AGM battery?
One main disadvantage of AGM batteries is their higher manufacturing costs, making them more expensive. They are also sensitive to overcharging and high voltages, requiring full charging between uses. This can make them unsuitable for certain applications where returning them to a full charge is difficult.
2. What happens if you charge an AGM battery with a normal charger?
AGM batteries require a slower and more stable charge compared to flooded batteries. If you charge an AGM battery with a standard battery charger, it can result in under or overcharging the battery. It is essential to use a charger specifically designed for AGM batteries to ensure proper and safe charging.
3. Do AGM batteries need a special charger?
Yes, AGM batteries require a special charger. They have lower internal resistance, allowing them to absorb higher currents. Regular battery chargers may not be suitable as they are designed for batteries with higher internal resistance. Using a charger specifically designed for AGM batteries ensures optimal charging and performance.
4. Can you jumpstart an AGM battery?
Yes, AGM batteries can be jumpstarted. There are jump starters specifically designed for AGM batteries that provide the necessary power and durability. Whether it's a flooded battery or an AGM battery, these jump starters can effectively jumpstart them.
5. Can I trickle charge an AGM battery?
Trickle charging an AGM battery is possible and recommended during off months. However, it is important to keep the battery within the safe temperature range of 32 to 104 degrees Fahrenheit. Using a trickle charger helps maintain the battery's charge and ensures its longevity.
6. Will any trickle charger work on an AGM battery?
While AGM batteries do not require a special charger, using a quality "smart" charger is beneficial. Regular constant voltage chargers operate at around 12.7 volts, which is suitable for AGM batteries. However, using a charger specifically designed for AGM batteries ensures optimal and efficient charging.
