How To Identify Agm Battery? Best For Consumer

Absorbed glass gel and mat (AGM) are commonly used in ships. Both types are considered safer than regular lead flooded cell batteries that contain sulfuric acid in each cell, which can leak acid if the outer casing is damaged, or the sea is rough. Gel and AGM batteries do not leak, even if the case gets poorly cracked. An AGM battery can be charged in the same way that a regular lead-acid battery can, but a gel battery requires a different charging method. Overcharging can cause the battery to overheat, which can damage the cells. It is essential for you to know what type of battery you have. You can read our Best AGM Battery Buying Guide to buy an AGM Battery.


  1. Check the label on the side or top of the marine battery to identify if it is a gel or AGM battery. All batteries their chemical composition and will have the words Gel or AGM on the label, possibly in more than one place.
  2. Check the charging instructions on the battery label, or refer to the instruction manual, if one came with your battery. The label or package insert will indicate that a gel battery needs to be recharged with a specially designed charger, or one with variable charge parameters. A gel battery must be charged at a lower rate than an AGM battery.
  3. Lift or weigh your marine battery. A gel battery is heavier than an AGM battery, due to its chemical composition. This can be difficult if you only have one battery so if you can not read the label on the battery, take it to a battery store and compare the weight of a gel and the AGM battery. While you are in the store, you can check prices. An AGM battery is cheaper than a gel battery, so if you have made a note of how much you have paid for your battery, you can compare the prices of a gel and the AGM battery.

Admittedly, an AGM battery costs less than a Gel battery, but it can be better if you choose the one that best suits the installation and the situation. More precisely, it is better to opt for an AGM DISCOVER battery if one can determine in advance that there is from time to time risk of deep discharge. Indeed, this range of battery will withstand this problem without a problem, but it is only necessary that the discharge time is short.

What is to be avoided in this type of situation is to choose a standard stationary AGM battery as its recharge is poor. It is also preferable not to opt for an AGM battery that has a floating life of fewer than six years, which often accompany solar kits since they have a very high risk of deterioration in a short period. Solar energy storage. The idea is to buy the one with a floating life of at least ten years. It should be noted that, apart from the AGM range of DISCOVER waterproof batteries, there are also many who choose to use a cyclic AGM battery for a photovoltaic system, such as the “Yuasa” range or the “NPC” range, which are less expensive. then the first range.
