Why eneloop batteries?

What is it that makes this rechargeable battery special?

Rechargeable!

eneloop can be charged 2100 times, before it needs to be replaced.

1 eneloop = 2100 alkaline batteries. Think of the cost savings alone.  Then think of how many alkaline batteries are sitting in a Landfill near you!.

eneloops are recyclable after there useful life.
Read below for the full story.

eneloop battery is delivered pre-charged to the store and is ready for immediate use following purchase. There is no need to charge-before-use.

Once the application has used all or some of the energy, eneloop can be charged like a conventional rechargeable battery, 2100 times, before it needs replacing.

Helping the environment

  • eneloop is rechargeable/reusable 2100 times
  • eneloop is recyclable. Just call 1-800-Recycle

Retains Capacity… Even After 12 Months

Once charged, eneloop retains its charged capacity even after 6 or 12 months of storage
(80% of Charged Capacity retained after 6 months, 70% Capacity after 12 months).

eneloop is pre charged and is ready for immediate use after purchase, straight from the pack. Just like Primary Batteries. There is no need to charge-before-use.

Comparison of remaining capacity over time

eneloop lasts longer in comparison with dry cell batteries

Key advantages of Ni-MH batteries are still inherent in eneloop:g
for example, superior performance in digital cameras (four times more shots than with alkaline) and the excellent stability even at low temperatures, for example while skiing.

And eneloop can be charged with virtually all modern chargers for Ni-MH batteries.
