Linktop EverPower™ Battery Longevity Technology

Redefining Long-Term Battery Performance for the Future of Smart Rings

Solving the Battery Aging Challenge Beyond the Battery Cell

Battery endurance has always been one of the most critical challenges in the smart ring industry.

Many smart rings can deliver impressive battery performance when they are new, achieving seven days or more of usage time. However, after several months of real-world use, some products experience noticeable battery degradation, with operating time gradually reduced to only one or two days, or even just several hours.

At Linktop, we recognized that this challenge is not simply a battery cell issue. The real challenge lies in how the battery is integrated, supported, and protected inside an ultra-compact wearable device.

Through thousands of experiments, reliability tests, and manufacturing optimizations, Linktop developed EverPower™ Battery Longevity Technology — an advanced battery reliability solution designed specifically for smart rings.

Beyond the Battery Cell: Creating the Ideal Operating Environment

Linktop engineers identified that extending battery lifespan requires more than improving the battery cell itself.

True battery longevity requires creating a better operating environment for the battery — one that reduces mechanical stress, accommodates natural expansion and contraction, and allows the battery to maintain stable performance throughout its lifetime.

Inside a smart ring, every millimeter matters. Due to the extremely limited internal space, the battery must operate under strict mechanical constraints. During long-term use, batteries naturally expand and contract as part of their normal electrochemical process.

Traditional rigid fixation methods can create continuous mechanical stress on the battery, accelerating aging and reducing long-term performance.

To overcome this challenge, Linktop redesigned the battery integration approach from the manufacturing process level.

Flexible Bonding Technology Creates Space for Battery “Breathing”

EverPower™ introduces an advanced elastic bonding technology that replaces conventional rigid attachment methods with a more flexible and stress-relieving solution.

This specially engineered bonding approach provides the battery with controlled flexibility, allowing it to naturally expand and contract during operation while reducing unnecessary mechanical pressure.

By creating additional “breathing space” for the battery, EverPower™ helps minimize internal stress and improves long-term stability.

Key benefits include:

• Reduced mechanical stress during long-term operation
• Improved battery stability and reliability
• More consistent endurance performance over time
• Extended product lifespan

Engineered for Years of Reliable Smart Ring Experience

A premium smart ring should not only perform well on the first day — it should continue delivering reliable performance after months and years of everyday use.

EverPower™ represents Linktop’s commitment to solving one of the most challenging problems in smart wearable technology: maintaining long-term battery performance in an ultra-small form factor.

Through advanced engineering, material innovation, and manufacturing expertise, Linktop enables smart rings to deliver a more reliable and sustainable user experience.
