Motorcycle Battery Types: A Definitive Guide

Motorcycle Battery Types: A Definitive Guide

The most exciting part of owning a motorcycle is being able to ride the winds on top of it. So it is not surprising if deciding which battery to buy for your vehicle falls quite low on your list of motorcycle-related priorities. If that is the case, then you have come to the right article.

Motorcycle batteries are mainly of three types. These are conventional wet cell batteries, AGM (absorbed glass mat) batteries, and gel cell batteries.

There are several points of difference and similarities between the three, and this article will lay them all out for you so that you can make a much more informed choice when purchasing a new battery for your beloved two-wheeler.

Brief Overview of the Different Types of Motorcycle Batteries

As has been mentioned before, motorcycle batteries are (mainly) available in three types: wet cell batteries, AGM batteries, and gel cell batteries. This section will be briefly discussing each of these most popular types of motorcycle batteries before comparing and contrasting their several features.

Wet Cell Batteries

These are also known as conventional or lead acid or flooded cell batteries. They are the most common type of motorcycle battery out there. These batteries are easily recognizable due to the rows of stoppers on the top.

Wet Cell Batteries

Wet cell batteries can be refilled using distilled water once they dry out. The liquid form electrolyte inside is also able to move freely, making these conventional batteries very vulnerable to spillage.

Absorbed Glass Mat (AGM) Batteries

This battery type also uses lead-acid. However, in this case, the liquid is trapped inside the battery between sheets of fiberglass. This also means that, if knocked over on its side, the acid will not spill out of the battery.

AGM Batteries

AGM batteries are quickly becoming the new ‘conventional’ motorcycle battery due to their efficiency and the middle ground they stand on between flooded cell batteries and gel cell batteries.

Gel Cell Batteries

Gel cell batteries use the same ingredient of lead-acid in them. However, the acid in gel cell batteries has had silica added to it, which gelatinizes it and effectively turns it spill-proof.

Gel Cell Batteries

A newer technology than the previous two, these batteries will also keep cool during hot weather.

Comparing the Three: Wet Cell vs. AGM vs. Gel Cell Batteries

Now that the three most common motorcycle batteries have been introduced, let us look deeper into their individual features and also see how they are different and similar among themselves.

Form of Lead Acid

All three of these batteries use lead-acid as their driving force. However, each contains the liquid in different forms.

In a wet cell battery, the acid moves freely inside the battery (giving way to easy spillage). As mentioned before, the acid is contained between a series of fiberglass sheets in an AGM (absorbed glass mat) battery, while the same liquid is turned into a gel using silica for gel cell batteries.


The tendency of traditional wet cell batteries to spill their contents (highly explosive and corrosive lead acid) when knocked over makes them quite an unsafe motorcycle battery.

In contrast, the trapped acid in AGM batteries and the gelatinized one in gel cell batteries make it so that chances of corrosion or of a hydrogen explosion are almost eliminated, making these batteries two of the safest lead-acid batteries for motorcycles.

Weight and Size

Though the three are similar in size and even in terms of appearance, because of the differences of their inner workings, their weights do vary.

While the conventional wet cell batteries weigh the most, gel cell batteries are a close second, with AGM batteries usually weighing the least.


Though gel cell and AGM batteries both cost more than wet cell batteries, the former tends to be considerably more expensive than the latter. So if you get a wet cell battery for 40 USD, you could get an AGM battery for around 15 USD more, while a gel cell battery will cost you a bit over 100 USD.


Though there are other types of motorcycle batteries available (such as lithium ion motorcycle batteries), the three batteries discussed above are the most common and widely used. As such, becoming familiar with their individual features is an important aspect of being a motorcycling enthusiast.

Even if you have a great motorcycle battery tender, or the best motorcycle jump starter, or an overall superb motorcycle, a good motorcycle battery is still essential for your riding experience to be consistently efficient and also enjoyable. Hopefully, this article has helped you choose the best one for you.
