Choosing a VRLA Battery Supplier
VRLA batteries (Valve Regulated Lead Acid) are closed lead-acid batteries that do not emit acid mist during charging and discharging. They are also referred to as maintenance free batteries, although they do require correct handling and management.
The electrolyte fluid used in these batteries contains water and sulfuric acid. It is immobilized in either a gel or Absorptive Glass Mat (AGM).
Battery Life
In a battery, electrolyte fluid allows electrons to move from one plate to another when they’re charged. The chemical reactions in the battery are what produce electricity and power potential, which is measured in amps. The higher the amps, the more powerful the battery is. Lithium ion batteries can offer four times the amount of energy, but they are also more expensive than lead-acid VRLA batteries.
The battery life of a VRLA battery is affected by several factors, including ambient temperature, cycle frequency, and charging attributes. For example, if the battery is subjected to high temperatures, it may overcharge, leading to reduced battery life.
Another factor is how long the battery has been in service. Batteries that have been in service for over 10 years will often need to be replaced. It’s important to test batteries regularly, and this can be done with ohmic testing equipment.
The type of battery used also plays a role in battery life expectancy. vrla battery supplier General purpose batteries are versatile and can be used in a variety of household mechanisms, such as sump pumps, alarms, riding toys, and UPS battery backups. However, they don’t have deep cycling capabilities. For those looking for a longer-term power source, gel batteries or AGM batteries are good options. They are ideal for cyclic applications that depend on batteries for daily power, such as solar systems or UPS backups.
Temperature Resistance
A battery is made of a positive lead plate and negative lead plate that are submerged in an electrolyte fluid that allows electrons to move between the plates. This reaction produces electricity that is stored in the battery for later use. The electrolyte fluid in a VRLA battery contains water mixed with sulfuric acid. This solution acts as a medium that carries the chemical reactions in the battery, which can produce electric currents for a variety of uses.
VRLA batteries are often used as backup power sources for telecommunications and UPS systems. These types of batteries require high reliability under harsh environmental conditions. These batteries have improved alloy and grid designs that offer resistance to corrosion and reduced float current under high ambient temperature conditions. They also have a vent system that releases and reseals at safe pressure levels to prevent thermal runaway.
While the design of a VRLA battery is ideal for cold environments, extreme heat can significantly reduce its amp capacity. The increased heat will cause the internal battery temperature to rise faster than it can be vented, which causes shedding of active material from the positive plate and reduces the battery’s overall performance. This is known as thermal runaway and can lead to a fire or battery explosion. These hazards are minimized by using a VRLA battery with a venting system that is safe and easy to operate.
Maintenance Free
The maintenance free nature of a vrla battery means you will not have to worry about the corrosive electrolyte that is present in flooded lead acid batteries. This means they are safer to use and can be mounted in any position. They also have a longer service life and can withstand harsh conditions. Additionally, they will not leak or burst.
There are two types of vrla batteries: gel and AGM. Gel batteries have silica added to the electrolyte, which prevents evaporation. AGM batteries have a special sponge-like matrix that absorbs the electrolyte. Both types of vrla batteries offer spill proof designs, making them safe to transport and store.
Another benefit of a vrla battery is that they are rechargeable. They can be charged with a battery charger lead acid car battery manufacturers and will hold their charge over long periods of time. This is especially important for off-grid applications where the battery may not be charged regularly.
The Optima YellowTop model is an AGM maintenance free battery that features spiral electrodes to ensure superior power and long life cycles. It offers 760 CCA abilities and 2 hours of reserve capacity for a total capacity of 70Ah (20h). This battery is constructed with heavy-duty materials to provide superior vibration resistance. It is an ideal choice for pickup trucks and SUVs that will drive on rough terrain. It can be used with vehicle electronics, and it comes with a 36-month warranty.
Safety
As with all lead-acid batteries, proper handling and safety protocols are necessary. Keeping staff trained and following these guidelines minimizes any risks associated with the battery. This includes taking care when removing, installing and performing maintenance on the VRLA battery. Those working with the battery should also be prepared to handle any hydrogen gas emitted during charging. This gas is flammable and can be explosive in a confined space.
Handling a VRLA battery involves the usual risk associated with lead and sulphuric acid, including burns to skin and eyes. It is recommended to wear rubber gloves, face masks and goggles. Ensure there is an adequate supply of water on hand to wash off any spilled electrolyte. In the event that sulphuric acid comes in contact with skin or mucus membranes, flush the area immediately and seek medical attention as required.
Since these batteries contain lead and dilute sulfuric acid, they must only be handled by qualified personnel. This includes those who are familiar with the battery type, installation and operating manual. Those working with the battery should remove any personal metal items such as watches and rings. It is also recommended to wear full eye protection and rubber gloves during battery work.
Batteries should be stored in a temperature and humidity controlled room with appropriate ventilation. This helps them dissipate heat, and prevents a build up of gasses within the cells which can cause internal damage. Those working with the battery should also have a neutralizing agent such as baking soda on hand to rinse off any exposed acid if it occurs.
