NOTE: Only compatible with i Series products.
As a patent product developed by Nitecore, the Nitecore NL2153HPI Li-Ion Rechargeable Battery is a proprietary 21700 rechargeable Li-ion battery featuring dual way output with positive and negative polarities at both ends and a high energy density. It enables a highly efficient output by minimising the loss of power due to internal resistance.
The dual polarities of the 21700 I series battery at both ends have broken the convention of linking the head and the tail of the flashlight in order to minimize its size and weight. The internal resistance is therefore greatly reduced to offering a direct energy conversion to power the device
Microporous barrier protects delicate internal components, coated with durable metallic film to guard against abrasion
Mercury free, lead free and cadmium free, low cost and environmentally friendly. Can be recharged over 500 times.
