How Fast Can an AGM Battery Be Charged?
An AGM battery can be charged fairly quickly, providing you have the proper equipment. Chargers with a temperature sensor are ideal for this type of battery, as they help protect it from being overcharged. By following the proper charging procedure, you can ensure that your AGM battery is ready to go when you need it.
Nine times out of ten, when someone mentions the word “battery,” the first thing that comes to mind is a car battery. But there are many different types of batteries, each with advantages and disadvantages. One such type is an AGM battery. AGM batteries are becoming more and more popular due to their high performance and long-life cycles. But one question that often comes up is: what is the AGM battery charge time? Keep reading to find out!
Do AGM batteries charge faster than lead-acid?
How fast can an AGM battery be charged? This is a question that many people have, and the answer may surprise you. Thanks to their construction, AGM batteries can be charged much more quickly than other types of batteries. We’ll explain how AGM batteries are charged and why they can be replenished quickly. We’ll also provide tips for charging your AGM battery as quickly as possible.
An AGM battery can be charged faster than a flooded lead-acid battery, but they generally have lower charge acceptance [more details below] when compared to an FLA. The primary reason that the recharge rate of an AGM is different from that of an FLA is in part due to the positive plate composition in each type of battery. AGM batteries typically use a 99.9% lead dioxide (PbO2) to cadmium sulfide (CdS) positive plate mixture, while FLA batteries use a lead-antimony oxide (PbSO4) to spongy lead (Pb) positive plate mixture. The different plate mixtures create different voltages during charging and discharging, which affects the speed at which each type of battery can be charged or discharged.
Can you charge a lead-acid battery with an AGM charger?
Most AGM batteries are maintenance-free, which means they can be used right out of the box without any special charging. However, if you’re looking for a long-life span and reliable performance from your battery, it will need to be properly charged before use. To do this safely, you should follow these steps:
- Make sure that there is no power coming into the battery terminals.
- Connect an external charger to both terminals on the top of the battery with jumper cables or alligator clips at least 6 inches in length
- Set voltage regulator on the charger between 14 volts DC and 16 volts DC
- Charge until current begins dropping off
- Disconnect the charger
- Leave connected 6 hours before using
