Iontra Charge Control technology receives UL CB Safety Certification!

Safety is a key concern for our customers in battery charging and especially for fast charge technologies such as ours. We are excited to announce that the Iontra Charge protocol has successfully achieved safety certification from UL Solutions on two widely used cylindrical rechargeable battery cells from a leading manufacturer:

→ 2500 mAh 18650 cell
→ 3000 mAh 21700 cell

The cells, cycled with Iontra charging, successfully passed both IEC 62133-2:2017 and IEC 62133-2:2017/AMD1:2021. The certified Iontra charge protocols allow charging at a higher 4.4 V peak charging voltage upper limit and a maximum charging current up to 20A peak.

We now enable charge time improvements on these cells by a factor of up to 2.3x over the standard battery specifications and by a factor of up to 1.6x over our customer’s best charge protocols.

With over 7 million hours of cycling data across several battery cell types and chemistries, and validation reports issued by four independent laboratories, Iontra is the leader in next-generation battery charging. We have proven battery charging solutions that dramatically improve the charge speed, cycle life, capacity utilization, cold weather charging, and safety of all rechargeable batteries.

Iontra is aggressively developing products with our customers and partners across a broad spectrum of battery-operated applications.

Iontra and Spectralink to bring ultra-long-lasting enterprise smartphones to market.

Iontra, a leader in advanced battery charging technology, and Spectralink, a pioneer in enterprise communication solutions, today announced a collaboration to bring extended cycle-life battery charging technology to Spectralink’s ruggedized enterprise smartphones.

Iontra’s technology significantly improves battery lifespan, reducing Spectralink’s warranty and service costs, while enhancing the end-user experience and lowering customers’ total cost of ownership. While Spectralink products already support superior battery life that significantly outlasts consumer devices and outpaces competitors, this partnership with Iontra unlocks truly unrivaled battery performance, further expanding the gap versus competition. Iontra has successfully demonstrated that its charging technology extended the Spectralink battery life to over 1800 cycles to 80% capacity (state of health), or three times longer than the current state of the industry.

“Spectralink is an ideal partner for Iontra as we refine our technology for the demanding cell phone market,” said Jeff Granato, CEO at Iontra. “Their ruggedized devices and commitment to quality align perfectly with our vision for extending battery cycle life in applications where this is mission critical.”

“At Spectralink, we are constantly looking for innovative ways to grow our position as an industry leader with exceptionally well-made, sustainable products that keep our customers coming back,” said Andrew Duncan, Vice President of Product and Marketing at Spectralink. “Iontra’s battery charging technology has the potential to be a game-changer for our ruggedized smartphones. By extending battery cycle life, we can ensure our customers maximize their investments and return on our products. We are excited to collaborate with Iontra on this initiative and look forward to showing the industry what is possible.”

Upon successful completion of both development phases, Iontra and Spectralink intend to take Iontra’s technology to market in specific Spectralink products.
