You can rely on lithium-ion batteries to provide uninterrupted communication services during power outages. They help maintain network stability and often include safety systems for real-time updates.

VRLA Battery Basics

Valve-Regulated Lead-Acid (VRLA) batteries have served as a reliable backup power source for decades. You find them in many outdoor and underground telecom facilities. VRLA batteries use a sealed design that prevents leaks and reduces maintenance. The safety valve inside the battery releases gas if the pressure gets too high, which keeps the battery safe during operation.

VRLA batteries use an immobilized electrolyte, either in a glass mat or gel form. This design lets you install them in different positions without worrying about spills. The batteries work by converting chemical energy into electrical energy through reactions between lead plates and sulfuric acid. The oxygen recombination cycle inside the battery helps minimize gas loss and lowers the need for maintenance.

• Common uses for VRLA batteries include:

  • Telecommunications facilities

  • Backup power for optical communication terminals

  • Information facilities

  • Outdoor and underground environments

You often see VRLA batteries housed in an Outdoor Battery Cabinet to protect them from dust, water, and temperature changes.

Pros and Cons for Outdoor Use

Lithium-ion Advantages and Drawbacks

You gain several important benefits when you choose lithium-ion batteries for outdoor base station backup. These batteries stand out for their long lifespan, high energy density, and low maintenance needs. The table below highlights some of the main advantages:

You also benefit from their ability to operate in a wide temperature range, from -20°C to 70°C. Their discharge performance remains stable even at higher temperatures, which helps you save energy and maintain consistent backup power.

Note: Lithium-ion batteries work well in an Outdoor Battery Cabinet, where temperature control and protection from the elements help maximize their performance.

However, you should consider some drawbacks. Lithium-ion batteries are sensitive to temperature extremes. They perform best around 20°C (68°F). In very cold climates, you may see reduced performance and increased energy use for heating. Charging in freezing conditions can be risky, possibly causing internal damage. Extreme temperatures can disrupt chemical processes, leading to lower power output and shorter battery life.

VRLA Advantages and Drawbacks

VRLA batteries offer you reliable and cost-effective backup power for telecom networks. You do not need to check electrolyte levels or add water, which reduces labor costs and the risk of mistakes. This makes VRLA batteries especially useful for remote sites where regular maintenance is difficult. Their sealed design prevents leaks and allows flexible installation.

You may pay more upfront for VRLA batteries, but their long service life and minimal maintenance often lead to savings over time. They fit well in outdoor environments, especially when housed in an Outdoor Battery Cabinet that shields them from dust, water, and temperature swings.

On the downside, VRLA batteries are heavier and bulkier than lithium-ion options. They also have a shorter lifespan and lower energy density. You may need to replace them more often, which can increase long-term costs and maintenance needs.

Key Comparison Factors

Cycle Life and Durability

You want your backup system to last as long as possible. Cycle life measures how many times you can charge and discharge a battery before its capacity drops below a usable level. Lithium-ion batteries stand out for their impressive cycle life. You can expect them to deliver between 3,000 and 5,000 cycles under typical outdoor conditions. VRLA batteries, on the other hand, usually provide only 300 to 500 cycles. Some gel-type VRLA batteries may reach up to 5,000 cycles, but most AGM or flooded types fall short.

• Lithium-ion batteries: 3,000–5,000+ cycles

• VRLA batteries: 300–500 cycles (AGM/flooded), 500–5,000 cycles (gel)

This difference means you replace lithium-ion batteries far less often. You save time and money on maintenance and avoid frequent disruptions. Durability also depends on how well you protect your batteries. Using an Outdoor Battery Cabinet helps shield both types from environmental stress, extending their lifespan.

Energy Density and Size

Energy density tells you how much power a battery stores for its size and weight. Lithium-ion batteries pack more energy into a smaller space. You need less room for installation, and you can use lighter cabinets. VRLA batteries have lower energy density, so you need larger cabinets and more floor space.

For equivalent energy storage, lithium-ion batteries occupy less than half the size and weigh less than a quarter of VRLA batteries. You can install more backup power in a compact Outdoor Battery Cabinet, making site planning easier and reducing installation costs.

Efficiency and Charge Rate

Efficiency and charge rate affect how quickly your backup system recovers after a power outage. Lithium-ion batteries charge about four times faster than VRLA batteries. You can reach full capacity in just 2–4 hours. VRLA batteries often need 8–16 hours to recharge fully. Faster charging means your base station returns to full readiness sooner, improving network reliability.

• Lithium-ion batteries: 2–4 hours to full charge

• VRLA batteries: 8–16 hours to full charge

Temperature also impacts efficiency. At -22°F, battery capacity drops by 50%. At 32°F, you lose about 20%. High temperatures can increase capacity slightly but may shorten battery life. Lithium-ion batteries risk thermal runaway in extreme heat, while VRLA batteries may suffer from electrolyte evaporation and grid corrosion. You can reduce these risks by installing batteries in an Outdoor Battery Cabinet with proper cooling and ventilation.

Cost and Value

Cost is a major factor when you choose a backup solution. VRLA batteries cost less upfront, but their total cost of ownership rises over time. You need to replace them every 3–5 years, which adds up. Lithium-ion batteries cost more initially, but they last up to 10 years without replacement. Over a decade, lithium-ion systems can cost nearly 53% less than VRLA systems.

You get a better return on investment with lithium-ion batteries. You avoid frequent replacements and reduce maintenance expenses. This long-term value makes lithium-ion batteries a smart choice for outdoor base station backup, especially when housed in a reliable Outdoor Battery Cabinet.

Maintenance and Safety

Maintenance requirements differ between battery types. VRLA batteries need regular cleaning of terminals, temperature control, and careful charging to avoid overcharging or undercharging. You must use proper ventilation to prevent hydrogen gas buildup. Personal protective equipment like goggles and acid-resistant gloves is important when handling these batteries.

• VRLA batteries: Clean terminals, control temperature, use proper charger, ventilate to avoid hydrogen gas buildup, wear PPE.

• Lithium-ion batteries: Use a Battery Management System (BMS) to monitor cells, rely on built-in safety features like fuses and overload protection, and benefit from thermal dissipation measures.

Safety incidents can occur with both types. Lithium-ion batteries may experience thermal runaway if exposed to high temperatures or overcharging. VRLA batteries can accumulate hydrogen gas, which is flammable. You can minimize risks by installing batteries in a well-ventilated Outdoor Battery Cabinet with monitoring systems.
