Dry Batteries Versus Wet Batteries: Which One is Best for Your UPS System

Why is Choosing the Right UPS System Batteries Important? 

 

During power outages and blackouts, Uninterrupted Power Supply (UPS) backups are crucial in operational efficiency and energy self-reliance. In India especially, one witnesses seasons of frequent power fluctuations, particularly in the monsoon and summer months, making UPS systems an inseparable part of modern industries. 

 

The choice of a correct battery is the most essential component of a UPS, which warrants making an informed decision while choosing UPS system batteries. 

Factors such as maintenance, lifespan, power outputs, and depth of discharge, among others, play a significant role in determining the ideal battery life for your UPS system. 

 

Lead acid batteries or wet batteries are predominantly used as UPS system batteries. However, Absorbed Glass Mats (AGM) or dry batteries are becoming increasingly popular along with lithium-ion batteries. 

 

This blog compares the two batteries to help make an informed decision for various UPS system applications.   

 

The Composition of Wet Batteries Versus Dry Batteries 

 

A wet battery or a lead acid battery comprises of lead plates suspended in a tank of diluted sulphuric acid.   

However, an Absorbed Glass Mat (AGM) or dry battery contains a glass mat separator that wicks the electrolyte between the lead plates. This material's structure allows the absorptive glass mat to absorb the electrolytes and retain them in a "dry" or suspended state instead of being in a free-flowing liquid form.   

 

What are the Maintenance Procedures and Advantages of Wet Batteries? 

 

While lead acid batteries are considered cost-effective and tried and tested UPS system batteries, they also require maintenance procedures, especially in larger UPS systems.   

Considering the nature of the liquid sulphuric acid in these batteries, thorough preventive maintenance is required every quarter.   

 

Ventilation and the position of these batteries are of utmost importance for operator safety. The electrochemical processes that occur within the battery to generate a current produce a gaseous material by-product. These gases must be expelled efficiently through the battery's vents to maintain an optimum internal temperature within the cell. Therefore, the foremost steps in battery maintenance is as follows: 


  1. Free the battery of all dust and debris, particularly around the air vents.   
  2. Lead acid batteries stored for future use must be kept in a cool environment upright to avoid any acid leakage. 
  3. The battery should be checked for any leaks that can compromise the safety of the UPS system. 

   

Once these preliminary steps are complete, the cables can be tightened and cleaned. 

The most significant maintenance procedure typical to wet batteries is topping up of the electrolyte solution. This solution comprises of sulphuric acid diluted with demineralized water. The ratio of the two liquids in the solution must be calculated and filled to precision as per the manufacturer's guidelines.   

 

Despite being bulky and requiring maintenance, these batteries offer many benefits, including higher power outputs, resistance to overcharging, and deeper discharge.   

 

What are the Maintenance Procedures and Advantages of Dry Batteries? 

 

Dry batteries require less maintenance and are more versatile as they can be operated in mobile operations. Their lifespan can be extended with simple practices like cleaning and good ventilation, as they are more prone to overheating due to a starved electrolyte construction. 

Store these batteries away from windows or direct heat sources to maintain optimum temperature in the cell. 

While these batteries are more expensive and need to be discarded once they stop supplying current, they also have numerous benefits that can be applied to specific requirements.   

Dry cells produce energy more efficiently. Although expensive, the less rigorous maintenance saves time and operational efficiency. Moreover, these batteries offer higher operator safety and are less likely to result in accidents.   

 

In conclusion, deciding between wet (lead acid) and dry (AGM) batteries for UPS power supply hinges on key considerations. Though bulky and demanding rigorous maintenance, wet batteries offer higher power outputs and resilience to overcharging. Conversely, dry batteries require less upkeep, cater to mobile operations, and boast efficient energy production. The choice should align with specific application needs, balancing maintenance preferences, operational efficiency, and safety considerations for reliable industrial UPS performance amid power fluctuations and outages.

Understanding Heat-Sealed Batteries: Enhancing Safety, Reliability, and Battery Longevity

By Unik Techno • March 28, 2025
Battery safety is critical in industries relying heavily on robust, dependable power sources such as electric forklifts, golf carts, and industrial machinery. One technology significantly advancing battery safety is heat-sealed battery construction . At UNIK Batteries, we utilise advanced heat-sealing techniques to provide superior safety, reliability, and longer battery life for demanding industrial applications. What Are Heat-Sealed Lead-Acid Batteries? Heat-sealed lead-acid batteries are constructed using a specialised sealing process where battery casings are permanently bonded through heat application. Unlike traditional battery sealing methods using adhesives or mechanical seals, heat sealing creates a highly durable, airtight enclosure, ideal for demanding industrial environments. Key Benefits of UNIK's Heat-Sealed Battery Technology Electrolyte Leakage Prevention Higher resistance levels, which may impact power output. Reduced charging efficiency, resulting in longer charge times. Increased operational strain, potentially leading to faster wear and tear. Here is why winter battery maintenance is essential: Proper care reduces the risk of cell damage due to freezing temperatures. Batteries that are well-maintained offer operational efficiency. Regular maintenance extends the life of your batteries, saving on replacement costs. Taking these steps will keep your i ndustrial forklift battery in peak condition, even when temperatures plummet. Lead Acid & Lithium-ion Battery Care in Cold Weather Maintenance of Lead Acid Batteries Lead acid batteries are more sensitive to cold temperatures because their electrolyte solution can freeze, particularly when the battery is in a low-charge state. For efficient battery care in cold weather, follow these tips: Charge fully after each use as a fully charged lead-acid battery is less likely to freeze. Store batteries in a temperature-controlled environment indoors or in a heated area to protect them from the elements. Inspect the battery for cracks or leaks, as these can worsen in the cold. Lead-acid batteries need adequate water to function correctly, so check and refill water levels routinely. Clean terminals regularly to prevent corrosion and improve conductivity. Lithium-ion Battery Maintenance While lithium-ion batteries fare better than lead acid batteries in colder weather, they still require care to avoid performance drops. Follow these tips for top-notch lithium-ion battery maintenance: When starting your material handling equipment, give your battery some time to warm up just as you would allow your car battery to reach an optimum temperature before driving. Lithium-ion batteries should not be charged at sub-zero temperatures, as this can lead to permanent damage. Lithium-ion batteries are more efficient when they maintain a moderate charge level in winter between 30-80%, to reduce strain on the cells. Following these steps can help ensure that both l ead acid and lithium-ion battery maintenance routines are winter-ready. Winter can be challenging for industrial forklift batteries , but with consistent battery care in cold weather , you can protect your investment and keep your operations running smoothly. By paying attention to winter battery maintenance and adjusting your care strategies for different battery types, you can enhance battery performance and extend its life, no matter how cold it gets. Protect your operations all season long! For more tailored solutions, explore our lithium-ion battery and lead acid battery sections to find the best fit for your material handling operations.
