What Does STD, AGM, and Gel Mean On a Battery Charger

The words STD, AGM, Gel, ENHC, Lithium, Calcium, and more are used in the maximum modern smart battery chargers. These contain more options and features than the older lead-acid battery chargers which are robust, simple, and less good. Modern chargers stand microprocessor-controlled equipment to prolong the operating lifetime of your batteries. 

Before going to the main charging works, users have to set the battery chargers efficiently. Know about the battery condition, type, temperature, or others. After knowing all about it, anyone can set up the modern or advanced battery charger correctly. But it is also important to verify the other preferences of completing the setting process. 

The extensively common smart battery charger options STD, AGM, Gel, and more are below:

STD 

The short answer is STD means standard wet or flooded lead-acid battery. This type of flooded battery is commonly accepted in the auto industry. It provides so much capacity to start the wagon and control loads of the electrical embellishment. Another thing, STD lends the ability to electrical clocks and PC frameworks while your vehicle is not running. 

Due to supplying the additional force, vehicles are capable of decreasing the electrical burden from the charging frame. Besides, this can level out voltage claws or forestall damage to various fractions of the electrical frame. 

AGM

What does AGM mean on a battery charger? It is a frequently asked question of the maximum battery lovers. The specific answer to the AGM means Absorbed Glass Mat lead-acid battery. That means it only has some lead-acid batteries. The AGM batteries contain an exceptional glass separator. 

But, sometimes you find the battery charger that contains AGM settings with “deep-cycle” and “gel” battery settings. It is one kind of problem because Gel batteries and AGM batteries are not the same.

Honestly, they have several and unique charging requirements. This is because while chargers are capable of charging AGM batteries, they are not suitable for non-gel batteries. Even though they damage batteries. Keep in mind that you may not start a car without a battery. 

Gel 

The word Gel means Gel-Cell lead-acid battery. It is a very delicate thing to charge the gel battery. If you make any mistake in charging time, it can ruin the battery. Even though the new one. For most applications, the gel batteries are not good enough although AGM batteries charge very easily and quickly. 

Gel-Cell battery uses silica or sand in turning through the gentle acid inside your battery into a midst liquid. The gel is unstable but its liquid makes it spill-proof. The gel can be burned just because of the high amperage, high discharge, quick charging, or other unexpected situations. 

Keep in mind that the wet/flooded, AGM and Gel-Cell batteries have the same features, chemistry, and requirement voltage. But these lead-acid batteries’ charging voltages are slightly different. 

The most crucial benefit of the modern battery chargers is their 100% capacitor protecting against undercharging and overcharging.

Other common options are also important for advanced battery chargers. Here is a table to focus on the calcium, lithium, float, and cycle. 

Labels Meaning 
Calcium Calcium hints charging mode of calcium-lead alloy plates for the common lead-acid batteries. Calcium lead-acid batteries are available in AGM, wet/flooded, or Gel-Cell. This is because users need to evaluate the battery’s recommended charging mode.
Lithium It indicates the battery charger setting the algorithms lithium batteries, not lead-acid batteries. Because they have several charging algorithms. The algorithm means that the Constant Current or Constant Voltage (CC/CV). 
Float It is another charging mode of batteries that use float or standby applications. 
Cycle If the charging mode focuses on deep cycle applications for the battery, it indicates the cycle. 

Anyway, the Solar PL2320 6V/12V Advanced Battery Charger has fewer specific features, labels, and options than the others. Here, the 6V/12V means the voltage of the charged battery. You may think, can I use a 12v charger for a 6v battery?  We say that is not good for the battery life. Try to avoid this method. 

However, the % charge batteries charge a percentage of the charged lead-acid battery. Besides, GEL, AGM, and STD are the types of batteries. 

You can also see the NOCO GENIUSPRO50 Battery Charger and Maintainer. It features a special battery charge meter that allows seeing the real battery charge.

What’s the Difference Between Standard and AGM on a Battery Charger?

There is no major difference between standard and AGM on a battery charger especially when you think about the charging way. Your AGM or standard battery charger provides a variation to the batteries as well as wipes out the sulfur off the plates. Then, restores it to the electrolyte permitting the electrons in flowing. 

You can find the difference when you’re charging the battery and it will lose the water. It can happen in the most common standard chargers. Sometimes due to the overcharge of any battery. It doesn’t play a major role in the strong standard battery. Because it allows you to include water back. 

But, most of the AGM batteries don’t allow you to include water back. Turning the hydrogen back into the water, AGM has a catalyst. Depending on the catalyst lifetime, the battery can survive. It is better to use the exact AGM battery charger to charge them properly. It also helps to increase the AGM battery life and prevent water loss as well as excess charging. 

Frequently Asked Questions

1. What Happens if You Charge an AGM Battery with a Normal Charger?

If you want to charge your AGM battery with a typical charger, the battery charges slowly and low. It also can happen to the gel cell batteries. The specific AGM battery charger has microprocessors to collect data from your battery. Therefore, it adjusts the voltage and current. 

2. Do AGM Batteries Require a Special Charger?

There is no need for any special charger to charge your AGM batteries. Just collect a quality smart charger like other batteries. That can be a regular ol’ constant voltage charger or similar. The average feeds out strength perhaps 12.7v, sometimes 12.6v.

3. Can a Lead-acid Battery Charger Charge an AGM Battery?

A lead-acid battery charger means an ordinary flooded lead-acid battery charger is well for charging AGM batteries. But, users have to monitor the charging process as needed. Another important thing, you find many GEL, AGM, and Calcium battery chargers that are better than regular lead-acid battery chargers. 

4. How Do You Tell If Your Battery is an STD, AGM, or Gel?

It is pretty simple to find out the battery types. Just see the top of your battery. If it is a Gel-filled lead-acid battery, it says “Gel-Filled” on the label. Any AGM lead-acid battery will say on the top “AGM” or “Absorbed Glass Mat”. You can also get other information on the label such as STD, sealed regulated valve, dry cell, non-spillable, or valve regulated. 

5. Is it a Marine Battery AGM or STD?

Fortunately, a Marine battery can be Flooded, Gel, and Absorbed Glass Mat types of the chemical. Three types of chemicals indicate the battery energy output and categories. 

6. What is the Difference Between STD AGM and Gel Batteries?

STD AGM and Gel batteries are quite similar. Only different of their charging rates. Compared to Gel batteries, AGM batteries are capable of dealing with higher charge and discharge rates. Another thing, STD and AGM lead-acid batteries are not as expensive as Gel batteries. You can’t use the gel battery in hot climates. 

7. Can You Charge a Standard Battery with an AGM Charger?

It is possible to charge a standard battery by using an AGM or gel cell battery charger. But, if the battery is discharged, you have to charge the charger as early as possible. Otherwise, your vehicle can’t start. 

The Bottom Line

Ultimately, AGM, STD, and Gel labels are the signal to the battery chargers. You should check the manufacturer’s guide before going to buy any new charger. It helps to get the particular features and labels that you expected. The inappropriate or wrong battery is not able to control the huge current.

So in short, AGM represents Absorbed Glass Mat lead-acid battery, STD means standard wet or flooded lead-acid battery, and Gel implies Gel-Cell lead-acid battery. At this moment, you learned that What Does STD, AGM, and Gel Mean On a Battery Charger and other relevant info.
