What Types Of Batteries Are There?

Batteries are devices capable of storing energy, supplying it, and being recharged several times during their useful life. (The device capable of storing energy for its water supply, when it is not rechargeable, is normally called a battery)

The concept of batteries that we normally handle can be defined as a “device formed by several cells capable of storing electrical energy for later use”, and as a term, it is applicable to any accumulator or set of several accumulators of electricity.

What are batteries used for?

Batteries are a source of DC voltage and are used to ensure the operation of critical electrical equipment or that do not have access to the electrical network. This makes them useful for a multitude of situations, some of the most common battery applications are:

  • Backup of computers and computer equipment, especially data and financial information through SAIs
  • Electric generation plants and substations for protection and control of disconnectors and relays
  • Telephone systems to support telephone service, especially emergency services
  • Industrial applications for protection and control
  • Portable data systems, etc …

What are batteries made of?

Basically, batteries are made up of cells, which in turn are made up of two electrodes (an anode and a cathode) made of different metals and immersed in an electrolyte solution (acid or alkaline) that will allow the chemical reactions that will release or store the Energy. Each of these cells, in their different compositions, has a capacity and by joining several cells, different battery capacities are achieved.

Are all battery the same?

Batteries

No, not at all, we can find many types of batteries, and although all of them have the basic function of storing electricity to supply it when needed, due to their different compositions and internal configurations we can find battery much more suitable than others for according to what uses.

It is important to know which battery is suitable for the use that we are going to give it since otherwise we can waste the particular characteristics of the product or exhaust the useful life of our battery in a few days due to improper use, remember that even outside The battery is similar or even if they share general specifications such as voltage and amperage, they will not give you the expected result if you do not choose the correct type of battery.

What types of cycles are there?

There are three primary types of battery discharge cycles, small, moderate, and deep. The small cycle occurs when only a small percentage of the total battery capacity is discharged and Following the same line of thought, the moderate and deep cycles (deep) are where the battery is discharged to a greater percentage of the total capacity. of the battery respectively.

How long do batteries last?

The answer to this question varies a lot and is directly related to the use that is given to it, its maintenance, recharge method, temperature, and other factors. Cases of the dead battery can be seen in just a few weeks due to severe overload effects, batteries damaged in less than a year even without being used, by being left in a hot garage without being charged, or battery that lasts less than half of the time. that they should due to improper use or charging. To maximize your battery life, the first thing to do is choose the right battery.

How do I know which battery is the right one?

Taking into account the use that is going to give it, and to make a general distinction, they could be separated into stationary batteries, cyclic batteries, and starter batteries:

  • Stationary batteries: GP series batteries are suitable for this use, for example as a UPS / UPS battery, battery for lighting systems, for alarms, for electronics, for solar energy applications, etc. In short, applications that are not battery intensive with deep discharges that would quickly deplete battery life.
  • Cyclic batteries: The EVX series provides us with cyclic or deep cycle batteries, these are the batteries suitable for the entire range of medium-sized electric vehicles, we are talking about wheelchairs, golf carts, mini electric motorcycles, quads, even some caravans, boats, or cars. These types of batteries are designed to be discharged up to 80% one time after another, something that would quickly deplete a stationary battery (cyclists have much thicker plates than stationary ones) but with a smaller surface area than SLIs and therefore, less instantaneous power like starter batteries require. It is important to understand that unlike batteries considered starter or SLI (Starting Light Ignition),
  • Starter batteries: They are commonly used to start or start engines. Starters or motor starters normally need a large amount of current in a very short time. Starter batteries have a large number of thin plates for maximum surface area. The plates are composed of a Lead “sponge”, similar in appearance to a very fine sponge. This allows a large surface area of ​​contact with the electrolyte, which is used for deep cycle, will quickly burn up to the bottom of the cells. Automotive batteries would fail after 30-150 deep cycles, whereas with normal or proper use 2-5% discharge starter could last for thousands of cycles … (These are not suitable for Caravans or Motorhomes). We do not currently sell these types of batteries.

What types of batteries are there?

According to its manufacture, VRLA is a type of lead-acid, and within these, the AGM since they are the batteries that you can buy in-store, to avoid confusion you can find several categories named for their main use, such as “batteries for UPS “(to use as a stationary battery) or” batteries for electric vehicles “(to use as a cyclic battery).

VRLA, what is that?

Lead Acid Batteries with Valve Regulated VRLA (Valve Regulated Lead Acid): The Lead Acid Battery with Valve Regulated (VRLA) is a backup battery used in portable equipment, SAIS (uninterruptible power supply), factory automation equipment, small lighting devices, alarm systems, electric carts, rechargeable vehicles, etc …


  The point is that every battery generates gasification during its normal operation, and if this is abundant, the pressure is created inside, therefore, it is not appropriate to completely seal a battery, and therefore, VRLA batteries have rubber caps that seal each cell.

 These plugs in case of excessive gassing will open releasing the internal pressure. That is, the caps for safety, regulate the eventual gas outlet. Because of this, AGMs, which carry these sealing caps, are also called Valvo Regulated Lead Acid (VRLA) batteries. With AGM, we can achieve all the advantages of GELs without acquiring any of their disadvantages.

  This type of battery is so widespread because AGM VRLA battery offers high performance, making the value for money very good. In addition to this advantage, the sealed construction eliminates the need to fill the battery with water, making it suitable for a multitude of applications where other batteries could be a problem.

What is the difference between GEL and AGM batteries?

Batteries

The 2 are a type of batteries called “dry”. Internally there is no electrolyte (acid) in a liquid state. That is, the electrolyte is immobilized in some way. During their normal operation, these sealed batteries do not emit gases to the outside, therefore there is no danger of corrosion in the vicinity of the battery. They receive one of the 2 definitions because technically there are two ways to immobilize the electrolyte:

  1. Transforming electrolyte into gelatin (GEL batteries): A silicone compound is added to the electrolyte, causing the liquid to turn into a solid mass like gelatin. If this battery breaks, there is no possibility of liquid leakage. This type of battery is worse in terms of performance, costs and lifespan.
  2. Using a glass fiber separator with great absorption capacity, in English AGM (Absorbed Glass Mat) to “separate” the positive plates from the negative ones. Absorbent fiberglass based spacers are used. When assembling the battery and adding the liquid electrolyte, it is absorbed by the AGM fiber which acts like a sponge. Like the gel battery, AGM batteries in case of breakage will not leak liquid, this technology is more modern than the so-called “gel” and also has the advantage that the battery can be installed lying down.

What are the advantages of AGM Batteries compared to Gel Batteries?

  • Since all the electrolyte is in the glass spacers, it cannot be spilled, even if the battery breaks. This means that since they offer no transportation hazards. Also, since they do not contain any liquid that can freeze and expand, they are practically immune to the risk of freezing.
  • The charging voltages are the same as for any conventional battery; there is no need for any special modifications and there are no incompatibility issues with chargers.
  • AGM batteries exhibit very low self-discharge – typically 1% to 3% discharge per month. This means that they can be stored for much longer periods without being charged.

What applications do AGM batteries have?

AGM batteries have various uses such as: Batteries for UPS, Emergency Lighting Equipment, Telephone Stations, Video-filming equipment, Child trolleys, mini-motorcycles, Electric Wheelchairs, Renewable Energy, Robotics, Car Golf, Medical Equipment, etc., and depending on their internal composition (anode and cathode materials, electrolyte composition, number of plates, etc.), some are more suitable than others for different applications, you can find different sections dedicated to each battery series available in our online store.

Is the battery charger important?

Of course, when recharging the batteries, the amount of current delivered by the charger must be taken care of, it must always be done according to the instructions of the battery manufacturer.

 If the current is excessive, abundant gassing is generated inside the battery and this can cause expansion (“swelling” and deformation) of the case and the battery becomes unusable. If the charger does not function properly for your battery, it will rapidly degrade it and lose its capabilities.
 

It is generally recommended to start charging with a current range equivalent in value to 1/10 of the battery capacity. For example, if it is a 12 volt 7 Ah battery (as used in emergency lighting equipment or most UPS), it is recommended to start the recharge with a current of 0.7 amps (provided that the manufacturer does not indicate otherwise). Slower reload rates are more efficient. 

A battery rated at 180Ah (amp-hours) in a 6 hour period can also be rated as 220Ah in a 20 hour period, and 260Ah in 48 hours. Much of this loss in efficiency is due to increased internal resistance at higher ampere ranges (internal resistance is not a constant) and is something like “the more you push.

  Always using the correct charger and following the proper methods to charge batteries is one of the keys to improving their life. Never allow a battery to overcharge or get hot. If the battery becomes hot to the touch on the outside, immediately unplug the charger and allow the battery to cool before continuing.

What is the internal resistance of a battery?

Part (or most) of the energy losses when charging or discharging batteries is due to their internal resistance. This lost energy is actually dissipated and converted to heat, which explains why batteries get hot when they are being charged. The lower the internal resistance … the much better, the battery can be considered more efficient.
