What Makes Eneloop The Best Rechargeable Battery


The new Panasonic eneloop battery incorporates a highly-durable super-lattice alloy which lessens the deterioration of this important alloy material. This super-lattice alloy increases the electrical capacity of the battery chemistry through lower internal resistance and delivers a long lasting, stable voltage output.

A new strong, thin outer case has also been added to the eneloop battery design in order to improve the internal cell space efficiency. The new case optimizes the balance of the components and when combined with other improvements have led to an increase in the number of times that eneloop batteries can be recharged.
