In the recent past, the world has undergone many technological changes, with people becoming more innovative. This has led to the establishment of more functional and durable products than traditional ones. The AGM (absorbed glass mat) battery is an improved battery designed in the early 80s to replace the flooded lead-acid battery. The AGM battery requires little to no matienence, and it does not spill.
On the other hand, a Flooded lead-acid battery is the kind of battery that has been widely used for over one and a half-century. They are also referred to as the wet cell battery for the liquid electrolyte found inside. The battery has been used for various applications, which has served until an alternative of AGM was found.
Below are some differences between an AGM battery and a lead-acid battery.
Maintenance needs
The lead-acid battery contains an electrolyte inside that emits gasses. Therefore, the battery needs to be in a well-aerated and open area for easy maintenance and emission of gases. On the other hand, the AGM battery is maintenance-free and emits no gases. This makes it best suited for vehicles that use batteries in trunks and beneath the seats.
Durability
The lead-acid battery is prone to vibrations and forceful movements. Therefore, they are delicate and can easily break when exposed to such conditions for a long time. Thus, one must be cautious when mounting them to minimize these effects. On the other hand, AGM is made up of glass mats and battery plates that make the structure unbreakable. Furthermore, they make the battery stronger and resistant to shock and vibration.
Internal resistance and power output
Internal resistance in the battery results in its voltage output. Therefore, the lower the opposition, the higher the output voltage. The AGM batteries have a resistance of as low as two percent, thus having a high power voltage. On the other hand, flooded lead-acid batteries have a resistance of between ten to fifteen percent. This, therefore, gives the AGM an upper hand as more potent than other lead acid batteries.
Charging time
The lower internal resistance in the AGM gives them an increased rate of charging compared to the lead-acid batteries. The AGM is five times faster in charging than the flooded lead-acid batteries. Furthermore, the AGM responds to ample power demands meeting the demand easily than any other lead-acid batteries.
Lifespan and self-discharge
The AGM has a lower self-discharge rate that lasts longer than the flooded lead-acid batteries. The AGM has a lifespan of up to seven years if well maintained, compared to other batteries that last for three to five years. Therefore, the AGMs last longer and will serve you better than any other batteries.
Conclusion
From the differences outlined above, it is evident that the advancement of AGM (absorbed glass mat) battery has come with a lot of benefits as compared to the past when people only used one brand of batteries. Therefore, it is recommended to go for an AGM battery when possible as opposed to lead-acid batteries.
