What You Need to Know 5 Battery Types Explained - Sealed, AGM, Gel

0 Published by admin Nov 30,2020

With all the various sorts of batteries on the market, it are often difficult to settle on the proper type for your application. We recommend that you simply take a couple of moments to seek out out more about the 5 commonest sorts of batteries.

1. Flooded Batteries

This is the normal engine start, tractor, and deep cycle-style battery. The liquid electrolyte is liberal to move within the cell compartment. The user has access to the individual cells and may add water because the battery dries out. Popular uses are engine starting and deep cycle designs.

For this sort of battery the standard absorption voltage range 14.4 to 14.9 volts; typical float voltage range 13.1 to 13.4 volts.

Pros: voltaic cell batteries are typically the simplest choice for backup power applications, utility, and grid energy storage.

Cons: Most of the cons of the flooded battery stem from the very fact that they contain free liquid that needs periodic inspection and maintenance. Flooded batteries also can be inadvertently damaged in forceful movement. Extreme climates can have a greater effect on the battery life thanks to the electrolyte solution inside the battery having the power to evaporate or freeze.

While flooded batteries do require maintenance, if taken care of properly this battery type will last longer than many of their counterparts.

5 Battery Types Explained

2. Sealed Batteries

This term can ask variety of various constructions, including only a small modification to the flooded style. therein case, albeit the user doesn't have access to the cell compartments, the interior structure remains basically an equivalent as a flooded battery. the sole difference is that the manufacturer has ensured that a sufficient amount of acid is within the battery to sustain the reaction under normal use throughout the battery warranty period. Other sorts of lead-acid batteries also are sealed, as explained below. very fashionable uses are engine starting and limited starting/deep cycle applications.

For this sort of battery the standard absorption voltage range 14.2 to 14.7 volts; typical float voltage range 13.1 to 13.4 volts.

Pros: These batteries are mentioned as maintenance-free batteries, and don't require watering service. Since there's no free liquid and minimal gassing, AGM batteries can perform better than flooded batteries in applications where maintenance is difficult to perform.

Cons: Users should lookout when charging this battery as over and undercharging can affect their life and performance. AGM batteries perform most reliably when their use is restricted to the discharge of no quite 50% of battery capacity.

3. VRLA Batteries

This stands for Valve Regulated Lead Acid battery. this is often also a sealed battery. The valve regulating mechanism allows for a secure escape of hydrogen and oxygen gasses during charging.

For this sort of battery the standard absorption voltage range 14.2 to 14.5 volts; typical float voltage range 13.2 to 13.5 volts.

VRLA batteries are common and located in many applications, like medical mobility scooters batteries and toy and alarm batteries.

4. AGM Batteries

The Absorbed Glass Mat construction allows the electrolyte to be suspended in close proximity with the plate's active material. In theory, this enhances both discharge and recharge efficiency. Actually, the AGM batteries are a variant of Sealed VRLA batteries, just a more advanced design. Popular usage includes high-performance engine starting, power sports, deep cycle, solar, and storage batteries.

For this sort of battery the standard absorption voltage range 14.4 to 15.0 volts; typical float voltage range 13.2 to 13.8 volts.

AGM batteries are common and located in many applications like RV batteries, boat batteries, motorcycle batteries, ATV batteries, and UPS & Telecom batteries for generators.

5. GEL Batteries

The Gel Cell Battery is analogous to the AGM battery style because the electrolyte is suspended, but different because technically the AGM battery remains considered to be a voltaic cell . The electrolyte during a gel cell battery features a silica additive that causes it to line up or stiffen. The recharge voltages on this sort of cell are less than the opposite sorts of lead acid battery. this is often probably the foremost sensitive cell in terms of adverse reactions to over-voltage charging. Gel batteries are best utilized in VERY DEEP cycle application and should last a touch longer in weather applications. If the wrong charger is employed on a Gel Cell battery, poor performance and premature failure is for certain . Battery chargers with gel profile will have information either on the unit, or within the manual, about gel compatibility.

For this sort of battery the standard absorption voltage range 14.0 to 14.2 volts; typical float voltage range 13.1 to 13.3 volts.


The better option ultimately depends upon the consumer’s requirements and therefore the intended use. the subsequent things should be considered when deciding which sort of battery to purchase:

● The application the battery

● The environment during which the battery are going to be placed

● How the battery are going to be recharged

● If you need bursts of power or a slow discharge rate

Once you answer the subsequent questions, you’ll be ready to determine which sort of battery would be best for you.

Gel batteries are not as common as AGM batteries, but are often found in deep discharge situations such as wheelchair and medical mobility batteries, trolling motor batteries, and RV deep cycle batteries.
