Direct replacement for Acroprint time clocks

Upgrade from depleted original cells

When the factory pack no longer holds a full shift charge, this 2000mAh unit restores the rated run time without modification. The jump is worth it if the device shows reduced backup or fails to power on after extended idle periods.

The pack delivers a fixed 9.6V output and cannot be charged by lithium or lead-acid chargers. Overcharge, over-discharge, over-voltage and short-circuit protection are built in. It is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.
