If not charged correctly, they may not operate efficiently, leading to shorter usage times and performance degradation. -
Heat Buildup:
Heat buildup can result from using an inappropriate charger that delivers a high charge rate. AGM batteries are sensitive to temperature, and excessive heat generated during charging can cause internal damage. According to a study by the Electric Power Research Institute (EPRI), excessive heat can hinder electrolyte performance and even result in thermal runaway, a situation where the battery temperature increases uncontrollably. -
Reduced Battery Lifespan:
Repeated use of a traditional charger might lead to a reduced lifespan for an AGM battery. Studies show that improper charging practices can cut the lifespan of a battery by as much as 50%. An AGM battery that has been consistently overcharged or undercharged may fail prematurely. -
Risk of Battery Failure:
The cumulative effects of overcharging, insufficient charging, and heat buildup can lead to catastrophic battery failure. This risk not only compromises device functionality but can also result in leaks or explosions. The National Fire Protection Association has documented incidents where improper charging led to severe battery failures, underscoring the importance of using chargers designed for AGM batteries.
In summary, using a traditional charger on an AGM battery can lead to various issues, including overcharging, insufficient charging, heat buildup, reduced lifespan, and potential battery failure.
