AGM, GEL and FLOODED Batteries: What is the Difference?

Batteries are an essential part of your everyday life. You rely on them to power everything from your phone, tablet and laptop to the lights in your house. But did you know that there are three different types of battery technology? AGM, GEL and FLOODED batteries can all be used for different purposes depending on what you need it for. In this blog post, we will explore the differences between these technologies so you can make a more informed decision next time you buy a new battery!

The AGM battery is the latest and greatest in lead-acid batteries. The separator consists of fibreglass between plates that create a “physical bond” by way of capillary action with an electrolyte consisting mostly of water, but also sulfuric acid or potassium hydroxide solution along with other additives like oils to make it more viscous so it can work inside any temperature range. This new design creates a spill-proof battery if ever exposed which makes them perfect for both consumers as well those who operate boats or aeroplanes where spills might cause catastrophic damage due to close quarters spaces such as cabins. The AGM battery is a maintenance-free, tight pack that withstands impacts and has low internal resistance. The higher output voltage from the lower resistance can decrease charging time while reducing heat losses to surrounding metal parts. This means they are not only capable of withstanding any hard impact thrown at them but also maintain their efficiency without worry for leaks or corrosion on other materials when being charged because gas recombines back into the liquid inside these batteries instead of leaking out as acid. You’re looking for a steady power supply to keep your equipment up and running. You know that AGM batteries are the way to go because they can do anything from powering emergency lights, on-grid solar systems, off-grid inverters or even just giving you an alternative energy solution should there be any kind of brownouts in the area again. You plug them into their respective sockets and head out with peace of mind knowing your devices won’t turn themselves off due to some unforeseen disaster like last year’s hurricane.

Flooded or “wet cell” batteries are the most commonly used battery on the market today. This is because they can be more easily charged and produce a higher amount of voltage than other types of batteries, such as gel cells. Flooded rechargeable lead-acid car batteries have electrodes that contain pure lead plates immersed in an electrolyte made up mostly water with sulfuric acid added for boosting power capacity and maintaining efficiency during discharge cycles when the electricity starts to flow from one plate to another through external electric circuits, which causes electrons to move inside each electrode’s metal lattice until it reaches its opposite terminal. The vents that release steam, acid and condensation also play a key role in the maintenance of flooded batteries. Flooded battery water must be replenished through these vents on a regular basis to keep them functioning properly.

GEL cell batteries are also sealed, but they have a different type of electrolyte, which is more viscous and gel-like than the liquid in flooded batteries. The GEL battery’s protective sealant contains silica to keep it from drying out or leaking into the environment. This jelly is then used as the perfect electrolyte. It must be taken with great care when dealing with GEL batteries to avoid exposing them to high amperages, which can cause a chemical reaction that will explode and destroy everything in its path! But can a simple GEL battery really be harmed by the intensity of an electrical current? After all, it is not like your average outlet. You might think that at least in this case you’re safe from any lasting damage to your electronic devices- after all, they are typically protected against electricity and there’s no way something as low voltage as what comes out of our outlets could hurt them right? Wrong! The truth is that just because high amperage situations don’t have enough power to cause serious problems on their own does not mean they cannot still do some considerable harm when mixed with other factors. While many types of batteries’ jelly fillings will merely shift around or squish together if subjected to too much electric force.

The main points are that AGM Flooded batteries have a longer life span than Gel or wet cell lead-acid batteries, but can cost more upfront because they don’t need a charging system and there is no water to monitor levels of for maintenance purposes. When it comes to choosing what type of battery you want for your vehicle, there are many factors to consider: price, longevity, weight capacity, etc… But one important thing is whether or not you will use the vehicle often enough where those other considerations won’t matter as much (i.e., if you take out your boat once every few months). If so then an AGM.

Hi, I'm Phil Borges.. thanks for reading.. My wife says I can't shut up about batteries so to save my marriage I've started this blog .. where I'd be ranting about batteries! Please leave a comment if you have any questions, I'm happy to help!
