Replacement Battery for Arcon E-pack S

The Estry nickel-metal hydride cell delivers 3.6 volts and 2500mAh capacity in a 60.35 by 54.6 by 22.2mm pack weighing 132.0g. It is built to match the original specifications for the E-pack S device. Certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Upgrading from a Depleted Original Pack

When the factory-fitted battery no longer holds a useful charge, this unit restores the rated 9.0Wh energy capacity. The jump is worth it if the device still meets your functional needs but runtime has fallen below acceptable levels. Protection circuits guard against overcharge, over-discharge, over-voltage and short-circuit events.

Sustained Load Behaviour

Under continuous draw the Ni-MH chemistry maintains a stable voltage curve without the sharp drop-off seen in short bursts. The integrated safety circuitry limits current extremes during prolonged operation. The one-year battery-pack rating reflects expected cycle life under normal duty rather than peak benchmark conditions.
