However, charging the AGM batteries requires a special charger. This is because these batteries are more stable and have to be charged slowly. The AGM battery chargers come with built-in technologies to detect the battery level and optimize the charging accordingly to prevent overcharging. Besides, the AGM battery charger can help in restoring dead batteries and maintaining them for a long life. The key lies in choosing the perfect AGM battery charger to suit your charging needs. Below are the primary features you need to check to end up with the perfect AGM battery charger for your batteries,
Voltage Compatibility: The output voltage of the AGM battery charger should suit the voltage of your battery. Most batteries operate at 6V and 12V while few of them operate at 24V. Some battery chargers support dual voltage levels so that you can charge batteries of different voltages. Ampere Rating: Higher the ampere rating of battery chargers, the faster will be the charging process. The least ampere rating of AGM battery chargers is 0.5 amps. However, some models have an ampere rating of 20 amps. But, anything with an ampere rating of more than 2 amps will do. Charging Modes: The AGM battery chargers have different charging modes including float mode, soft start mode, and reconditioning mode. The charging modes get activated automatically based on the battery condition and helps in delivering optimal charge to the battery. Always, prefer the charger with most charging modes for maximum charging optimization.
Apart from these, there are several other secondary features you need to be aware of before making your decision. If you don’t want to complicate this by digging deeper, you can check out the Best AGM Battery Chargers 2023 to choose one from the list.
