Why use Eveready's Rechargeable batteries

The original Rechargeable batteries were manufactured with Nickel-cadmium (Ni-Cd) construction. Cadmium is harmful to the environment and this led to further research resulting in the manufacturing of the Nickel-metal hydride (Ni-MH) battery.


The success of nickel-metal hydride has been driven by high energy density and the use of environmentally friendly metals. The modern nickel-metal hydride battery offers up to 40% higher energy density compared to the standard nickel-cadmium.

Eveready strongly believes in protecting the environment, as evident in our environmental awards and policies.   The Eveready Rechargeable battery is of the Ni-MH construction and is therefore environmentally friendly. Not withstanding this serious advantage above the Ni-Cd construction, there are some other pro’s & con’s of using the Ni-MH Vs the Ni-Cd. Here are but a few:

Advantages:

  • Performance – Ni-MH will out perform the standard Ni-Cd battery in high drain applications.
  • Capacity – The amount of energy stored within a Ni-MH battery is 30-40% higher than standard Nickel-Cadmium. The individual capacities are up to 2500mAh for AA & 900mAh for AAA. In case of a digital camera, this allows you to take more photos.
  • Memory effect – Ni-MH batteries can be charged or "topped-up” at any time, while Ni-Cd batteries must be fully discharged before charging. There is no Memory effect with Ni-MH batteries.
  • Value - Value for money due to usage of more than 500 charges – discharge cycles

Disadvantages:

  • Relatively short storage – Maximum three years. Cool temperature and a partial charge slow aging. Performance degrades if stored at elevated temperatures.
  • Limited discharge current – although nickel-metal-hydride is capable of delivering high discharge currents, heavy load reduces the battery's cycle life.
  • Charging – Requires slightly longer charge times than nickel-cadmium & Trickle charge settings are critical because the battery cannot absorb overcharge.
  • High maintenance – Should be exercised (charge-discharge cycle) once in every 3 months.
  • Emergency devices – Not suitable for Emergency flashlights & smoke detectors.
