best Battery Chargers for AGM batteries

Buying Guide


After going through our best battery chargers for AGM batteries, you are probably now wondering which one is suitable for you. You will have to consider several factors before purchasing the right AGM battery charger. We will discuss these factors below to make the selection process easier.

1. Charger type

There are three different types of chargers used to boost the all-round performance levels of AGM batteries.

Each type work in specific ways to ensure your AGM battery functions properly. The three types of AGM battery chargers are conventional chargers, maintainer chargers, and restorer chargers.

Conventional chargers

This set of chargers do the obvious: they boost the power levels and help to restore sulfuric levels of AGM batteries. They are the most popular of the three types of battery chargers in the market.

The reasons are their affordability and their compatibility with any type of vehicle batteries, even motorbikes. Within the shortest possible time, you get your vehicle battery powered up, and you are ready to move around.

They are capable of restoring dead batteries back to life and have them functioning at optimum performance levels.

Maintainer chargers

As the name implies, these chargers just help to maintain the battery charge when it is still connected. It does this without charging the battery fully.

Maintainer chargers are designed for people who do not want their batteries to die as they work.

It is important to note that an AGM battery that is not functioning properly and gradually losing power will lose its charge after some time.

Restorer chargers

This category of chargers is the most expensive of the three types. Restorer chargers help to get rid of all accumulated sediments on the AGM cells, which prevent the battery from getting charged or working as is expected.

This type of charger is found mostly in heavy-duty automobile workshops and some mechanic shops.

In summary, be sure to know the exact kind of battery charger you need to power your battery type.

2. Quality

You want to go for a battery charger manufactured by a well-known company. Do extensive research on the battery charger you want to buy before spending money.

Quality battery chargers should have top scores for durability. Quality also ensures the battery charger is safe for use.

Another way to ensure quality is the product warranty. The companies that offer product warranty stand by their products.

3. Price

If you are just looking for a standard battery charger for your AGM battery, then there is no need to go overboard and spend money on battery chargers used by industrial automobile firms.

Why should you spend over $200 on a battery charger when you can get a good one for $100?

If the affordable one is manufactured by a company with a questionable reputation for the quality of their products, you should avoid it.

4. Safety measures

Battery chargers cannot work without utilizing electricity, and this is quite dangerous. The best battery chargers for AGM batteries are equipped with safety features and protect both the charger and the battery as well.

An example is the automatic discharge function that prevents overcharging the AGM battery. This features also help to prolong the lifespan of your AGM battery and have it performing at optimum levels.

5. Average charging time

An AGM battery charges fully with a battery charger from 2 to 10 hours. The average charging time of a battery charger determines the capability to fully charging a battery in the shortest possible time.

Expensive battery chargers have very high charging capabilities.

6. Discharge rate

This factor is very important in choosing a battery charger. Each battery charger comes with its discharge rating, signified in ampere-hours.

The amount of current provided by a battery in an hour is known as the Ampere hours. For instance, an AGM battery with a discharge rating of 100 aH, should be able to sufficiently deliver 100 Amperes of electric current in an hour.

FAQs - Frequently Asked Questions

1. What is the meaning of AGM?

AGM stands for an absorbed glass mat. It is a class of lead-acid battery that is designed to be spill-proof, with the sulfuric acid easily soaked up by the fiberglass mat on the inside.

AGM batteries have high conductivity levels because of their low internal resistance.


2. Which is better- AGM or Lead-acid battery? 

AGM batteries are a class under lead-acid batteries but are better when compared to the typical sealed lead-acid batteries.

This is evident in their maintenance-free design, safety measures, better power rating, longer life cycle, and shelf life. 


3. How long does it take to charge an AGM battery fully? 

Determining the exact amount of time to charge an AGM battery is not that easy. One thing is sure, though - it takes a longer amount of time to recharge an AGM battery with a lower charge.

With that said, recharging should not exceed 12 hours. You need to monitor the battery temperature while charging it. Stop charging it when the temperature is more than 125℉.


4. Can a regular battery charger be used to charge an AGM battery?

Using a regular charger to charge AGM batteries can result in damage due to overheating. This is because AGM batteries have been designed to charge slowly and with low charge.

One needs to use the right AGM battery charger to get an AGM battery fully charged while preventing damage to the AGM cells due to overcharging.


5. What is the life span of an AGM battery?

An AGM battery should typically last between three to five years. This is because their chemical composition makes them last for a good number of years.

If an AGM battery is maintained properly, it can last as long as eight years. 


6. What is the specific voltage to charge a battery?

Ideally, you can charge your batteries at a voltage ranging from 13.8 to 15. However, it pretty much depends on the features of the battery charger. 


Our top pick

Getting the best battery charger for AGM batteries is a matter of choice. However, you need to consider a number of factors, understand the working of a battery charger, and how safe it is to use.
