Maintenance Tips For SLA Battery s

SLA battery s

The S-Series is one of the leading general-duty sealed lead-acid batteries on the market today. Using an absorbent glass mat (AGM) design to suspend the electrolyte, this battery offers maintenance-free performance and leak-proof performance. Exponential Power offers several additional models as well.

Typical applications

SLA batteries work by reversing the process of charging a standard battery, converting electrical energy from the charger to chemical energy in the battery. The alternator in a vehicle or the charger used for other applications can charge a battery in this manner. Regardless of how a battery is charged, it is always important to keep the terminals clean and free of contamination.

SLA batteries are widely used in a variety of industries. They can be used for backup systems in alarm control panels, fire suppression systems, access control systems, CCTV, electric fences, biometric systems, and many more. They can also be used in medical applications that require high quality and safety. They can power medical devices like defibrillators and pumps, as well as incubators and ventilators.

In addition to their emergency lighting applications, SLA batteries are also commonly used in ATVs and motorcycles. They also provide backup power for cellular repeater towers. In addition to being widely used, SLA batteries come in a variety of sizes and voltages. If you’re looking for a battery that will keep you going in case of a power outage, consider SLA or VRLA batteries.

Another common use of SLA batteries is in cars, where their high capacity is useful for cranking the car’s engine. Unlike standard batteries, SLA batteries don’t suffer from the memory effect, which occurs in flooded and NiMH batteries. Memory effect occurs when batteries are repeatedly charged before all the energy is drained. This can shorten the battery’s life and decrease its operating time.

Another type of SLA battery is the AGM battery. It has a special glass mat that wicks the electrolyte between the battery plates. It is valve-regulated and sealed. Because the gel is absorbed by the battery’s plates, it’s not as susceptible to overcharging. Unlike AGM batteries, gel cells have a limited capacity and are not suitable for automobile applications.

Charge voltage limit

To maximize battery life, the charge voltage limit for an SLA battery should not be exceeded. The maximum voltage an SLA battery can handle varies by state of charge. This means that a battery with a higher charge voltage should SLA battery s be recharged more often. However, a battery with a lower charge voltage should be recharged less often.

In order to maximize battery performance, the recommended voltage limit for an SLA battery should be set according to the specifications of the manufacturer. If the recommended voltage threshold is not followed, sulfation will gradually degrade the battery’s capacity. Typically, the pressure relief valve for a Hawker SLA is set at 345 kPa (50 psi), which is higher than that for a conventional low-pressure lead acid battery.

Overcharging a SLA battery may result in a high temperature buildup that destroys the battery. If the voltage is too low, the current will stop before the battery reaches its maximum capacity, and lead sulfate will remain on the electrodes, reducing battery capacity.

While the charge voltage limit for an SLA battery is not usually higher than 13.5 volts, the maximum charge voltage for a fully discharged battery should be at least 14.3 VDC. If you can achieve this, the voltage limit will be much lower. A higher voltage will be better for the battery, but you should not overcharge it.

When charging an SLA battery, you should follow a multi-stage charge cycle with an adjustable voltage limit. This will allow the battery to receive the correct amount of charge. A multi-stage charger will apply a constant-current charge, a topping charge, and a float charge. The constant-current charge stage will charge the battery to 70 percent, and the slow-topping charge will finish the remaining 30 percent. This is necessary for the health of the SLA battery. The slow-topping charge is essential to compensate for the self-discharge of the battery.


Gassing SLA battery s are designed to operate under certain conditions. While there are some advantages to this design, it may not be suitable for all circumstances. Some situations may be out of the scope of an SLA battery, such as confined space applications. In such cases, it may be better to choose a wet cell battery. These batteries have low costs per kWh and can be mounted in any position.

While the battery is not designed to release gass on a regular basis, it can develop gasses due to excessive overcharging. This is caused by a sudden increase in the pressure inside the battery and boiling of the electrolyte. This gas will then vent out of the battery through a safety valve.

The battery should be charged to about 80% before undergoing gassing. Charge it for a few hours and then take specific gravity readings every hour to check for correct levels. Make sure that the level of electrolyte is about 1/8” below the bottom of the fill well. You should also make sure that the vent caps are tightly in place. Batteries often attract dust, so it is best to keep them covered.

AGM batteries are generally safer for the environment and for your safety. As long as you store the battery in a ventilated area, it is safe to use. However, the batteries should never be placed near open flames. And be sure to use a charger that is designed for them. Another alternative is to use valve-regulated lead acid batteries, which are also known as gel batteries. The gel batteries have a silica additive in the electrolyte.

The gassing process in a lead-acid battery takes place during the first part of the charging process. Lead sulfate reacts with hydrogen ions and oxygen in the electrolyte. If the voltage is low, this lead sulfate will start to accumulate. This leads to a loss of capacity and reduced life of the battery.

Self-discharge rate

When it comes to lead acid batteries, the self-discharge rate is one of the most important characteristics to consider. This discharge rate is primarily determined by the amount of lead that is present in the battery. It is also influenced by factors like temperature and charging regimes.

SLA batteries have an average self-discharge rate of 3% per month, but the rate can be higher if the temperature is too high or too cold. The most effective way to prevent self-discharge is to charge the battery every three months and store it in a cool, dry place.

A good ROC indicates that a battery was manufactured with good quality materials and that manufacturing processes were controlled. A poor ROC can indicate multiple manufacturing defects and deficiencies within the battery. The self-discharge rate of such a battery can be three to four times higher than the battery’s original capacity. You cannot stop the self-discharge rate of a battery, but you can minimize its effect by avoiding high temperatures and direct sunlight.

The internal design of a battery is crucial for determining its lifespan and performance. A battery should be specifically matched to its intended application in order to provide the longest possible life. In automotive applications, for example, a car battery is intended to provide thousands of rapid starting discharges. Moreover, a car battery is only able to sustain slow long discharges for a few times before irreparable damage occurs. In contrast, SLA batteries have been designed to last for many years in multipurpose, high-rate, temperature-variation, and standby-only applications.

The charge current limits of a SLA battery are listed in the specifications sheet. These limitations vary with each battery. In general, a battery’s C-5 charge level is the safest level for most SLA batteries. It is important to remember that discharge changes SLA battery s the chemical composition of the battery plates, which is vital for its life.


If you own an SLA battery, you should follow certain maintenance steps to keep it in good shape. For starters, it is crucial to charge it regularly. Overcharging can damage the battery, causing it to lose its charge. You should also clean the terminals to prevent corrosion. To do so, you can use a wire terminal brush or a solution of water and baking soda.

Next, you should clean the top and post connections of the battery. If there are any leaks in these areas, you should replace them or repair them. In addition, ensure that all battery cables are secure. Frayed or broken cables are extremely dangerous, so be sure to replace or repair them. You should also tighten the connections and cables to the correct specification. You should also wear protective gear when performing these activities.

In addition, remember that temperature is a major factor when it comes to the life of SLA batteries. The battery’s capacity and lifespan will depend on its operating temperature, the number of cycles, and how often the battery is charged and discharged. Maintaining your SLA battery will ensure that you get the most out of its life.

SLA batteries require routine maintenance to ensure safety. It is important to keep the electrolyte in good condition. The battery should be checked daily and refilled with fresh electrolyte every three years. Clean the battery terminal connections regularly to ensure good current flow. Also, check the exterior of your battery for corrosion and any other contaminates that may cause further discharge.

In addition to cleaning, you should regularly monitor the water level in your SLA battery. Remember that it can freeze up if its capacity drops below 40%. Fortunately, you can prevent this problem by using a special battery watering system.
