VRLA Battery Supplier

VRLA batteries are also known as SLA or valve-regulated lead acid battery. These maintenance-free batteries are position insensitive and feature a vent to control internal pressure. They are the ideal choice for telecommunication sectors as backup power sources.

These batteries are critical for the operation of DC load equipment in power plants and substations. Their failure can result in major accidents.


VRLA batteries are maintenance-free and leak-proof. They have a safety vent that opens when there is too much internal pressure. This feature protects the battery from exploding, and also helps prevent the battery from overcharging or discharging. They are also position insensitive and can be used in many locations, including controlled environmental vaults and telecommunications cabinets. In addition, they are ideal for use in telecommunications applications because they meet the criteria of Telcordia Technologies requirements document GR-4228.

These batteries are designed to work as backup power supplies for DC load equipment in case of a loss of AC electricity. They are widely used as emergency power supplies in industrial applications, and are one of the most reliable battery types on the market. However, they can suffer from several different aging modes and need to be inspected regularly.

The failure of a VRLA battery in a standby DC power supply system can have serious consequences. The failure of a single battery can cause the opening and closing mechanisms of high-voltage circuit breakers to fail, which can lead to dangerous accidents. This problem can be prevented by properly maintaining the battery.

VRLA batteries have been around for quite some time, but they are not as popular vrla battery supplier as lithium-ion batteries, which offer a host of advantages over the wet cell. Lithium batteries are designed as energy cells, so they can perform up to ten times more discharge cycles than a VRLA battery and can charge four times faster. Moreover, they have a lower initial cost and require less frequent replacements than VRLA batteries.


Battery maintenance services can help extend the life of your back-up power systems. Whether your batteries are the heartbeat of your UPS system, backup for your telecommunications or switchgear, or provide emergency lighting, they are critical to keeping your mission-critical operations up and running during a power outage. But they only work if you maintain them. Several factors can affect battery life, including temperature and charge/discharge cycles. The right preventative maintenance program can keep your batteries in top condition.

Battery maintenance programs can include voltage, ac ripple and internal ohmic testing. These tests can pinpoint the condition of a battery prior to failure, enabling you to replace it before it fails. It’s also important to clean your batteries regularly. They tend to attract dirt and grime, which can shorten their lifespan. Using a damp sponge can help eliminate these deposits.

The difference between flooded and VRLA batteries is their rate of self-discharge. VRLA batteries are sealed lead acid, meaning they contain a small amount of electrolyte inside the cells that is not accessible to the outside atmosphere. This is why they are also referred to as “leak-proof” and “position insensitive.” They also feature a safety pressure relief valve. In contrast, flooded batteries allow oxygen to recombine with hydrogen evolved on the positive plates and escape through the vent, creating water.


A VRLA battery is a type of lead-acid battery that immobilizes the electrolyte, making it spill proof and suitable for confined spaces. It can be used in UPS backups, wheelchairs, and cars, among other applications. These batteries have several safety features, including a one-way pressure relief valve, which vents gas if the rate of hydrogen evolution lead acid car battery manufacturers becomes too high. This makes them safer than traditional flooded lead acid batteries, which emit corrosive fumes during charging and discharging.

AVRLA batteries have a very low charging voltage, so you should use only an appropriate battery charger with them. In addition, you should keep the battery in a cool, dry location to protect it from heat and cold.

You should also monitor the technical parameters of a VRLA battery on a regular basis to check for any changes in their performance. This will help you identify and respond to any issues promptly. In addition, you should regularly test the charge/discharge cycle of your battery to make sure it is functioning properly.

If you notice any signs of damage or deterioration, you should inspect the battery and replace it immediately. It is important to note that VRLA batteries require a different type of maintenance than flooded lead-acid batteries. Therefore, it is essential to have the proper tools and equipment for handling and installing them.


Compared to lead-acid batteries, VRLA batteries have lower initial purchase and maintenance costs. They also have better rechargeable life and operate well in high ambient temperature environments. They are a popular choice for UPS energy backups, especially in areas that require longer runtimes. The COVID-19 pandemic and its resulting lockdown impositions have boosted the demand for backup batteries at hospitals and food companies, which has increased business opportunities for VRLA battery suppliers.

In addition to being leak proof, VRLA batteries do not produce acid mist during charging and discharging that can corrode equipment or pollute the environment. They have a one-way safety pressure relief valve that opens only when the rate of hydrogen evolution becomes too rapid to be safely recombined with oxygen to form water. They also have a special design that allows them to be installed in any position.

However, if you use this type of battery in a telecommunications application, you must ensure that your equipment is located in an airtight and sealed enclosure or hut. In addition, you should only use a VRLA battery with an ohmic measurement type of battery charger. This will prevent overcharging, which can damage the battery permanently. Lithium-ion batteries have been growing in popularity as UPS power backups for data centers, despite their higher initial cost. But the price decrease of these batteries over the past few years has made them more competitive with VRLA batteries.
