What are NiMH batteries?

Nickel Metal Hydride (NiMH) batteries are rechargeable batteries known for their reliability and environmentally friendly characteristics.

NiMH batteries are widely used as an alternative to NiCd batteries, which are restricted in many portable applications due to environmental regulations.

Key advantages of NiMH batteries include:

High energy capacity
No cadmium content
Rechargeable hundreds of times
Minimal memory effect
Stable performance across many applications

NiMH batteries are commonly used in:

Flashlights and headlamps
Security and emergency equipment
Consumer electronics
Industrial applications

Thanks to their strong price-performance ratio, NiMH batteries are a practical and sustainable choice for professional use.

Elfa supplies a wide range of NiMH batteries as well as compatible standard and fast chargers.
