Iontra Receives UL CB Safety Certification

Thought Leadership

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.
