Backup power for elevators and lifts requires reliability, safety, and consistent performance. When the mains power fails, the right battery system ensures that passengers remain safe and critical lift functions continue smoothly.

At Valen Power, we specialise in designing dependable energy storage solutions for essential applications, including elevators and lifts. In this guide, our experts break down the differences between VRLA (Valve Regulated Lead Acid) and Lithium Iron Phosphate (LiFePO4) batteries to help you choose the right technology for your system.

Understanding AGM Battery Technology

Absorbent Glass Mat (AGM) batteries are a type of VRLA battery that use a fine fiberglass mat to absorb the electrolyte. Unlike traditional wet cell batteries, AGM batteries keep the acid immobilised within the separator, allowing for a spill-proof and maintenance-free design.

AGM batteries are engineered to deliver short bursts of high power, which makes them ideal for standby applications such as elevator backup systems. When a power outage occurs, AGM batteries respond instantly, ensuring uninterrupted lift operation until the main power is restored.

Key Advantages of AGM Batteries for Elevators and Lifts

• Fast discharge capability for emergency backup

• Reliable performance in standby conditions

• Maintenance-free operation and sealed design

• Proven technology trusted by many lift manufacturers

Valen AGM Battery Options

Valen Power offers two advanced AGM battery ranges suitable for elevator and lift applications:

Valen Topin AGM Batteries

The Valen Topin 12 TP 12 range is a standard VRLA rechargeable battery designed for dependable standby use. These batteries are safe, cost-effective, and easy to install.

However, for lifts with heavy or frequent power draw, the Valen X-CEL range is often a better fit.

Valen X-CEL AGM Batteries

The Valen X-CEL Advanced 12 VX 14 batteries take AGM performance to the next level. With pure lead plates and tin-enhanced paste, these batteries resist sulphation and maintain longer service life.

Since sulphation is a common cause of early battery failure in standby applications, X-CEL’s design ensures durability even when the battery remains idle for extended periods.

For long-term reliability and reduced maintenance, Valen X-CEL is the preferred choice for elevator and lift backup power.

Lithium Phosphate Battery Technology

For buildings where lifts are heavily used or subject to frequent power fluctuations, Lithium Iron Phosphate (LiFePO4) batteries can provide superior performance and longer cycle life.

Lithium batteries come equipped with an integrated Battery Management System (BMS), which continuously monitors and protects the battery cells. This ensures optimal performance, longer lifespan, and improved safety under demanding operating conditions.

Benefits of Lithium Batteries in Lift Applications

• High energy density with reduced footprint

• Long cycle life and deep discharge capability

• Intelligent battery management and monitoring

• Lightweight construction, ideal for compact lift systems

Although Lithium batteries differ significantly from VRLA systems, they can be configured to suit specific elevator setups, particularly in remote or space-restricted environments.

Which Battery Type Should You Choose?

The right battery for your elevator or lift depends on usage frequency, power draw, space availability, and environmental conditions.

• For standard standby applications, AGM VRLA batteries remain the most cost-effective and reliable option.

• For high-demand or cyclic use, Lithium batteries deliver superior performance, longevity, and system intelligence.

At Valen Power, our team can help you assess your requirements and specify the ideal solution to match your lift system.
