Building on high quality and reliability, the L4 Pro features the innovative  Refresh Function at its core, offering a comprehensive battery health management solution. You can enjoy the performance of a fresh battery every day!

Refresh Your Ni-MH Batteries, Extend Their Life

Over time, you may notice that your Ni-MH batteries don’t last long as well as they used to. This is often attributed to the “memory effect,” where incomplete discharges lead to reduced battery capacity. However, a lesser-known but equally important factor is the reversible issues that can develop during battery use. For example, insoluble crystals or passivation layers can form on the electrodes, reducing their activity and limiting battery performance. Additionally, the electrolyte may become unevenly distributed, further affecting the battery’s overall efficiency.  Simply recharging the battery won’t solve this issue – a full discharge is needed to help restore the battery’s maximum capacity. That’s where the Refresh Function of the L4 Pro comes in.

The L4 Pro shifts the focus from just charging to battery health maintenance. By eliminating the memory effect and addressing these reversible issues,, it helps them retain their full capacity, extends their lifespan, and reduces waste. This not only saves you money in the long run but also makes it an environmentally friendly choice.  

• Discharge Mode – Ideal for quick maintenance of newer batteries, this mode performs a single discharge-charge cycle.

• Refresh Mode – Designed for older or frequently used batteries, this mode intelligently determines the discharge-charge cycles based on the battery condition.

Advanced Charging Technology You Can Trust

In addition to the Refresh Function, the L4 Pro inherits our signature intelligent charging technology, ensuring safe and efficient charging for your batteries.

• Mixed Charging Compatibility – Charge 1 to 4 AA/AAA Ni-MH or 1.5V Li-ion batteries simultaneously, regardless of brand and capacity.

• Smart Detection – Auto-detects the battery type and selects the optimal charging mode for maximum efficiency and safety.

• Fuller and Cooler Charging – Utilizes 5 full-charge detection methods to achieve real fully charged, while our unique CVSA tech reduces battery temperature, helping to extend battery life.

The Best Charger for AA/AAA Ni-MH Batteries

The L4 Pro is an essential tool for anyone who relies on Ni–MH batteries for their devices, such as:
