Absorbed Glass Mat Batteries- Absorbed Glass Mat batteries AGM are now a very popular battery

Absorbed Glass Mat Batteries

Many people think that GEL and Absorbed Glass Mat Batteries are the same

Many people buying new golf batteries or mobility batteries. Therefore, believe that the two types of battery are the same. They are very similar.Hence, they are a deep cycle with a low discharge. Because they do not spill they are classed as sealed.Therefore, may be mounted in any position.For this reason, are safe to use in a confined area. Naturally, and may be carried safely.

Absorbed Glass Mat batteries. Are filled with a type of fibreglass material.As expected, that is fitted inside the battery and then soaked with the electrolyte between the batteries plates. Therefore, this makes the battery leak proof.In other words, if the battery casing is broken.Accordingly, then no acid will leak out. This type of battery is also the most popular here in

the UK (in my opinion this is due to the price difference) these are usually much cheaper batteries, in particular with the golfing fraternity.

Absorbed Glass Mat Batteries

GEL batteries have filled a type of silica gel mixed with the electrolyte making a thick jelly that allows the electrons to flow through the plates. Once again as in the other kind, they do not leak when the casing is broken.

One of the most common reasons. Thus, for people using the Absorbed Glass Mat Batteries. Is it can give out a high burst of amps if required to do so. Of course,they can also be charged with a standard battery charger. So, and an alternator if necessary.Also, they have a longer life expectancy.Especially, if these batteries are not fully discharged between discharges. In my opinion, this is a mistake that people make, they fully discharge their batteries too often causing premature failure, I think that people should keep a backup battery as a spare so as to not allow their batteries to become too discharged.

 GEL batteries as stated before cost more than Absorbed Glass Mat Batteries

But offer better-working conditions.Especially, in hotter climates. Although, this does not affect us here in the UK. The big problem with gel batteries is that they must be charged correctly. Hence, or failure will follow. If you have a GEL charger then stick to a GEL battery.For this reason, they are designed especially for these types of battery. GEL  should not be charged with an alternator. Unless appropriate adjustments are made. Another battery that is starting to appear in the marketplace. Naturally, is the Lithium-Ion battery.So, watch out for this one.
To conclude. We think that Absorbed Glass Mat. Now has the upper hand and unless you only have an own charger on your golf buggy or mobility scooter you would be better off buying AGM.

AGM Batteries-Versus Traditional Batteries-VSP News: Kolman’s Korner, Episode 69 –

AGM Batteries

Trojan AGM batteries are being promoted to upgrade the power needs for more powerful cars and trucks.

Brad Bisaillon, director of strategic accounts, North America and Europe, for the Trojan Battery Company, discusses the differences between AGM Batteries and traditional batteries.


A good battery video to watch for the Trojan battery fans amongst,us and this includes me.


Trojan batteries versus traditional batteries

AGM batteries are once again becoming more popular in the car and transport industry, because of the constant strain that on board computers and other electronics have to absorb on the modern vehicles of today.

This is most evident on the start-stop technology that we use in today’s cars. This system requires many more starting cycles that can only be handled by a start-stop AGM battery. These batteries come to us in the Varta brand, one of the companies that are owned by Johnson controls who are the world’s number one battery manufacturer.

Deep cycle AGM batteries are made with thicker plates and a stronger grid system. They are also practically dry compared to a normal free flow lead acid battery, that are fitted into the regular gasoline engine car, that are primarily used to start the car and also for the cars lighting. The plates are much thinner and perforated with small holes; this gives the battery more power up front to start the car’s engine and is known as CCA (cold cracking amps).

The AGM Batteries have much thicker plates and is virtually dry and is completely sealed. The plates are covered with glass matting that absorbs the acid, making the battery virtually dry and able to take a much larger charge and discharge. This was found to be the best option for the new start-stop technology.

There are now other makes of cars such as the Jeep models that come with an Optima AGM battery that does the same job of supplying a good CCA for starting purposes and also keeping the cars computer system and many on-board electronics fully serviced, by the fact that the battery has a deep cycle capability.

This also applies to the trucking industry. Trojan are informing truck fleet users, the benefits of fitting Trojan batteries to their trucks, replacing the normal lead acid batteries that are fitted as original equipment.

The Trojan  are one of the best quality batteries in the world and are manufactured to alloy very deep cycles, without damaging the battery. The necessity to upgrade the battery comes with the fact that these vehicles use much more power with high demand at certain times, making it necessary to fit a deep cycle battery. The drivers sleeper cab is very often fitted with cooking facilities and even a TV like a mini RV vehicle, and so requires an AGM battery such as the Trojan Deep Cycle Batteries.

Golf cart batteries-Deep Cycle

Golf cart batteries are also deep-cycle and are the most suitable for use in electric car conversions, where you do not have the access to state-of-the art technology, like electric car manufacturers have.

Deep cycle batteries can be depleted to 80% of their charge before they need to be topped up.

( Marine batteries, are sometimes called ‘deep-cycle’ and sometimes used for electric vehicles, but are not recommended because they are not true deep-cycle, more like ‘mid-cycle’ and have too short a life.).

Electric car batteries work the opposite way.

Batteries are used in gas car engines as well as electric cars. Electric car batteries are deep-cycle ones. Shallow-cycle means that if you leave the lights on overnight, 5% of the battery will be depleted and it will go flat. You’ll have to find some kind person with a jump lead to give you back enough charge to get you going again.

Golf cart batteries-Deep Cycle

Batteries are used in gas car engines as well as electric cars. Gas cars use shallow-cycle batteries. Electric cart batteries are deep-cycle ones. Deep cycle batteries are used in solar panels, so that when the sun does shine, you can get most of that power over a long period. Other types of deep-cycle batteries are those used in heavy-duty machinery, like forklifts.

Electric car batteries work the opposite way. They are made of stronger, metal electrolyte plates. They are ‘deep-cycle’, because they need to provide a lot of power over a long period before recharging is possible. A gas-car battery is made up of light foil electrolyte plates. This small battery is only needed to power the ignition, lights and other accessories. As a result AGM deep cycle batteries are still king.

Johnson Controls AGM-Brings AGM Battery Technology to North America

Post Updated 2nd Jan 2014

Johnson Controls AGM;AGM batteries are made from the addition of “Absorbed Glass Matting” to the lead acid.

Johnson Controls AGM

This battery technology is used widely in Europe for Mobility vehicles and golf buggy applications These batteries are sealed and do not leak, giving the batteries a safer environment if they are involved in an accident. They are now been used in the new “Stop Start” technology coming into the market in Europe, on cars such as BMW. When the car stops say at a red light then the engine stops when the accelerator is pressed to start the car the engine restarts.Another advantage with the Johnson Controls AGM batteries is that they can be discharged to a lower state and will still retain the power required to re-start a car combustion engine. These batteries will be coming more popular in the next few years, and you can see more about this subject in the excellent article bellow.

AftermarketNews.com (AMN)Johnson Controls Brings AGM Batteries Technology to North America.

“America Aftermarket News.com (AMN) Johnson Controls AGM, Brings AGM Battery Technology to North America According to Mike Carr, vice president and general manager North…”There are several benefits in opting for AGM batteries over conventional batteries, including longer life in demanding applications (such as today’s vehicles with an ever-increasing level of electronic content), as well as being completely spill-proof and maintenance free. The AGM batteries can last up to two times as long as conventional batteries, according to Lisa Franklin, director AGM product and market development”… the author of this post is Amy Antenora.
