Types of 12 Volt Storage Battery

Whether you are camping with your family, going off the grid or live full-time in an RV or boat, you depend on a 12 volt battery to meet your power needs. This battery type is the most versatile and efficient power storage solution.

However, choosing the right 12 volt battery for your needs can be confusing. This article will help you understand the different battery types available, including their features, maintenance requirements and cold cranking amps.

Flooded Lead Acid Battery

The flooded lead acid battery is the most commonly used type of lead-acid battery. It has the ability to provide a high surge current and is suitable for starting applications, off-grid renewable energy systems, and heavy-duty machinery applications. It also has a lower cost than other battery types and provides an excellent return on investment. However, it can have a low lifespan due to its evaporating electrolyte solution. Therefore, it is important to regularly check and maintain the battery by topping up the water levels with distilled water.

Flooded batteries contain liquid electrolyte within which the positive and negative electrode plates are immersed. They are also known as wet cell batteries. These batteries produce energy with a series of chemical reactions between metal lead and lead dioxide on the positive plate and metal lead and sulfate on the negative plate.

It is important to note that when handling a flooded battery, you should be careful to avoid exposure to sulfuric acid and take all necessary safety precautions. This includes wearing gloves, eye protection, and a face mask when working with 12v-storage-battery the battery. It is also recommended to use a bicarbonate of soda solution to neutralize any spilled acid. In addition, you should not charge the battery if the specific gravity reading is above 1.002. You can determine if your battery is flooded by gently shaking it and seeing if the liquid inside moves.

Sealed Valve Regulated Lead Acid Battery

Often referred to as SLA or VRLA, sealed lead acid batteries are maintenance free, leak-proof and position insensitive. They have a safety vent to release gas in case of excessive internal pressure build-up. They have a longer design life compared to flooded batteries.

Battery manufacturers use a variety of additives to improve the performance of lead acid batteries. Doping agents such as antimony and tin increase deep cycling, but also cause higher water consumption and the need for regular equalization. Calcium reduces self-discharge, but is not effective for high cycling.

A battery’s separators have a significant impact on the battery’s efficiency and design life. The pore volume, acid absorbency and compression characteristics of the separator determine the rate of gas recombination and oxygen transfer within the battery.

AGM (Absorptive Glass Mat) batteries have a porous, sponge-like material for separators that allows ions to pass through but is not electrically conductive. This makes AGM battery separators extremely durable and enables a larger designed capacity for a given size. This results in a battery that can deliver higher currents for a longer duration and has excellent cycling performance at high depth-of-discharge. Canbat’s AGM batteries have a long history of reliable service in taxi fleets, ambulances and other specialty vehicles. AGM batteries are available in several sizes to fit your application.

Lithium Ion Battery

Lithium ion batteries power the laptops, phones, solar panels and electric cars that have revolutionized our lives over the past couple of decades. They have an excellent energy density that allows them to store a lot of power in a small space.

When the battery is powering a device, the voltage difference created by the electrons flowing from the positive to the negative electrode powers it. The flow of electrons occurs via a conductive ionic liquid electrolyte that separates the two composite electrodes. When the battery is not charging, the current from the external circuit is interrupted and the electrons accumulated in the negative electrode travel back to the positive. This is called discharging.

During recharge, the lithium ions migrate between the electrodes by reversible intercalation into an electrically conducting solid. This insertion happens between the layered graphene structures in the anode. This is reversible and the capacity of the anode is not compromised by multiple charge/discharge cycles.

Extended storage of the battery results in the growth of a thin film of solid lithium metal at the anode surface. This decreases cycling capacity and increases ohmic resistance of the SEI.

Lithium ion batteries have new safety hurdles to overcome that previous Household integrated solar system chemistries did not, including the possibility of fires. This is why they require an advanced battery management system (BMS) and a protective external shell to prevent abuse.

Gel Battery

GEL batteries (also called dry cell batteries) do not contain a liquid electrolyte but instead use a gel-like substance that is similar to petroleum jelly. This thixotropic substance is formed when the battery acid is mixed with silica gel. This is the main difference between this type of battery and the other lead-acid options.

Because of the lack of liquid, gel batteries are completely leak-proof and don’t require any maintenance or clean up. Additionally, there is no risk of sulfuric acid spilling out of the casing which can be dangerous to anyone who comes into contact with it. Gel batteries also have a much higher tolerance for heat than traditional lead-acid batteries and can operate effectively in extreme temperatures.

Gel batteries have a longer lifespan than other types of lead-acid batteries and can withstand a high number of charge cycles. They are also a great choice for powering systems that need to run on a cycle basis, like solar panels and inverters.

The one way safety valves in gel batteries, unlike those in wet cells, reduce excess pressure and gassing during charging. This allows the internal gasses to recombine into water and greatly reduces energy loss. A gel battery is also a good choice for applications that need to be installed in a tight space because it is less likely to spill electrolyte.
