AGM vs. GEL Batteries -Differences

In Electric by Magnus SellénLeave a Comment

AGM batteries

When trying to decide which battery to choose, it is important to consider AGM batteries in comparison to GEL batteries. Both batteries have something to offer, but there are also big differences.

The more you learn about these options, the easier it will be for you to make the right decision. There are some people who will benefit more from one than the other. In this article, we will take a look at both types of batteries so that you will have the information you need in the future.

Design

Both AGM and GEL batteries have a sealed design and are regulated by a series of valves. This prevents leakage, which can be a real problem with many other types of batteries available on the market.

The pressure valves used in these batteries retain the toxic gases when they are flooded. This ultimately means that no maintenance is required, which is always a good thing. These batteries are both quite durable and suitable for everyday use, and can withstand daily use for long periods of time.

AGM batteries usually consist of a mixture of silicon and battery acid. This creates a thicker substance that cannot leak like conventional battery acid. The semi-solidified substance inside the batteries has holes drilled into it to allow oxygen to flow freely between the positive and negative plates.

GEL batteries have an insulated membrane that keeps the electrolyte in a stationary position at all times. They also have a fiberglass mat membrane, which is normally extremely thin. This allows high output power without the general bulkiness of many other batteries. The acid that protects the plates gives them superior discharge capabilities. The fiberglass in these batteries prevents problems with air pockets that can negatively affect performance.

Cycle Life

One of the more important things to consider when looking at different car batteries is the lifespan that each one has. This varies considerably depending on the manufacturer of the battery and the particular model. If you plan to use a battery as a backup power source, this is not a very important factor. AGM batteries tend to have a longer cycle life, which can result in more power and higher overall consumption.

The slow discharge rates of GEL batteries result in longer charging times. The faster discharge rates of AGM batteries mean that you cannot continue charging for quite as long.

AGM batteries should not be discharged below 50% as they may not be able to return to their original capacity. Undercharging these batteries can have a particularly detrimental effect on their performance, and you must bear this in mind. Overcharging is never good either, but this is not a concern with these batteries.

Capacity

GEL batteries usually have a lower capacity, which means that they need to be recharged more often than their AGM counterparts. While this varies by model, there is a fairly constant difference between the two technologies.

Temperature Performance

If you need a battery that still works well in very cold weather, AGM batteries are recommended. The fact is that GEL batteries do not work nearly as well when the temperature drops below 32 degrees Celsius. This could be a particularly important factor to consider if you live in an area with very cold temperatures.

It is important to remember that AGM batteries can have some performance problems, especially in hot weather. If these batteries are exposed to extreme heat long enough, they will begin to wear out quickly. This shortens their life considerably, which is why it is so important to be aware of the ambient temperature.

Durability/Life Expectancy

GEL batteries

You will find that GEL batteries offer incredible durability and are designed to stand the test of time. These batteries can be discharged up to 90% and still have a solid cycle life. With a GEL battery, you can achieve about 2,500 cycles at only thirty percent, while an AGM battery can achieve about 1,200 cycles. Even at 90% discharge, an average GEL battery still delivers at least 700 cycles.

AGM batteries are designed to resist vibration, which can be a major problem with some other modern batteries. GEL batteries are only able to withstand a moderate amount of vibration before they suffer significant damage.

Cost

Although GEL batteries offer a longer average life than AGM batteries, they also tend to be more expensive. With GEL batteries you definitely get what you pay for, but they are not for the budget-conscious.

Charging

It should be remembered that GEL cell batteries require special chargers. Using the wrong charger can significantly reduce the performance of these batteries over time. AGM batteries are somewhat easier to recharge because you can use a variety of chargers.

Applications

AGM batteries are ideal for a wide range of applications. They are a good choice for those who need a rechargeable energy source in a remote and/or very cold location. These batteries are used in everything from robotics to motor homes.

GEL batteries are excellent for charging electronics because their overall design means they are less likely to cause damage to these devices. If you need a slow and deep discharge, this is the best option you have. They can also be excellent for powering solar panel systems in both commercial and residential applications.

Final Thoughts

Because there are so many differences between AGM and GEL batteries, it is important that you carefully consider your options. You should consider a number of things, including what you want to use the battery for. It is also a good idea to consider the temperatures to which the battery will be exposed. Both types of batteries have a lot to offer for different applications. It is also important to find a reputable brand before you buy anything in particular.
