![]() ![]() With a standard battery this isn't much of an issue because you can add water back, but with an AGM battery you can't add water back. The difference is when you charge a battery it loses water, and this is especially true with strong standard chargers or if you over charge a battery. The charger applies a pulse to the battery and this breaks the sulfur off the plates and restores it to the electrolyte allowing the electrons to flow freely. Though you technically don't have to have an AGM charger for an AGM battery, it is a good idea to have one ConclusionĪGM and standard batteries both charge in the same way. You spent good money on an AGM battery, so make sure you charge it properly and don't damage it and get a charger designed for it. That is why even though you technically don't have to have an AGM charger for an AGM battery, it is a good idea to have one. The standard charger will charge the battery and if monitored will not cause harm to the AGM battery, especially if used on the lowest setting, but if you are not careful, then it will over charge the battery and lead to the AGM batteries life being cut short. The technical answer is no you don't have too. So, now that you understand the difference between a standard charger and an AGM charger, a lot of people will ask if you have to use an AGM charger for an AGM battery. Do You Have To Use AGM Charger On AGM Battery? These special chargers will normally stop charging once the battery is fully charged, and won't start recharging again till needed, meaning they can be left connected. As it gets closed to being fully charged, then the charge can slow down, so as not to over charge the battery. This means that it has computers that can monitor the level of charge in the battery. That is why they make chargers designed for AGM batteries and are labeled as that.Ī charger labeled for use with AGM batteries is normally more of a battery maintainer. ![]() However, you don't want to under charge the battery either. This is because if you add a low amount of pulse over a longer period of time not as much heat will be made, so the battery won't get as hot.Īlso, if you charge it slowly, then you are less likely to over charge the battery and cause damage. When it comes to charging, that means you should charge an AGM battery low and slow. ![]() Since water can not be added directly back to an AGM battery though, then once the catalyst is gone inside, it is gone, so you should do everything to prevent the need for it. These matts suspend the electrolyte and makes it so the battery does not leak. In an AGM battery there are glass matts that absorb the liquid and AGM stands for Absorbed glass matts. For an AGM battery there is a catalyst such as platinum, that is able to turn the hydrogen atoms that are created when charging back into the water. This means that water that is lost has to get back in a different way. AGM BatteryĪn AGM battery on the other hand though, you can not add water back to it. The reason this water lose isn't a big deal though, is that water can be added back into a standard battery making it so it will function the same. Over charging of a standard battery again does not cause much damage and just causes water to be lost. This is when pulses are still being sent in, but there is no more sulfur to be broke off. A standard battery though the heat goes away with the water that is being lost and normally it doesn't get hot enough for damage to occur.Ĭharging a battery fast though can also lead to over charging. The problem with charging a battery fast though is that it causes a lose of the water inside of the mixture. By charging the battery fast you can start using it again quicker. This is because standard batteries with liquid in them are not hurt by being charged fast. When you recharge a standard battery, the charger normally puts off a strong pulse and charges quickly. In a standard battery the electrons are housed in just the liquid mixture and a part of that mixture is water. This frees the electrons and puts them back into the electrolyte where they are able to move thru the battery again and provide juice to whatever the battery is connected too. When the electrons are stuck to the plates, instead of being able to flow thru the battery, that is when the battery is considered low on charge.īy charging the battery a pulse is sent into the battery and it breaks the sulfur build up off the plates. Over time, the sulfur and the electrons with it stick to the metal plates inside the battery and builds up. The electrolyte is a mixture of sulfur and some other parts. ![]() In a battery you have the electrolyte which is a liquid that holds the electrons. Agm vs Standard Battery Charging What Does Charging Do?įirst though before getting into the specifics of different types of chargers and which to use with what kind of battery we will cover what charging actually does. ![]()
