When it comes to charging batteries, understanding the compatibility between different types of chargers and batteries is crucial for safety, efficiency, and longevity. One question we frequently receive at HIMAX Electronics is whether a NiMH (Nickel-Metal Hydride) battery charger can safely charge lithium-ion batteries. In this article, we will explore the key differences between these two battery technologies and why mixing chargers could be a dangerous mistake.

 

Understanding NiMH and Lithium-Ion Batteries

Before diving into the charging capabilities, let’s first understand the key differences between NiMH and lithium-ion batteries.

NiMH Batteries:

  • Typically used in everyday devices such as remote controls, flashlights, and toys.
  • Offer moderate energy density and longer cycle life compared to older battery types.
  • Operate at a nominal voltage of 1.2V.

Lithium-Ion Batteries:

  • Commonly used in smartphones, laptops, electric vehicles, and high-performance robotics.
  • Known for their high energy density, lighter weight, and longer lifespan.
  • Lithium-ion batteries, like the ones HIMAX Electronicsspecializes in, typically operate at voltages around 3.7V per cell.
