# Changing Batteries

To change batteries, perform the following steps:

1. Twist the reader’s end cap, and take it off.

2. Hold the reader in an upright position and the battery slides out of the handle.

   Note: You may need to shake the reader slightly.
   WARNING: The battery used in these devices may present a risk of fire or chemical burn if mistreated. Do not disassemble, heat above 60 ºC (140 ºF), or incinerate. Replace battery with Cognex DMA-HHBATTERY-01 only. Any other battery may present a risk of fire or explosion.

3. Put the replacement battery into the slot with the metal contact pins pushed in first. A small triangle on one side of the battery is indicating the correct placement.

   Tip: A small triangle on one side of the battery is also indicating the correct placement.

4. Put the end cap back on and twist it. Make sure that the triangle aligns with the circle when the cover is locked.

5. If using DMA-CBASE-01, place the battery in the spare battery charger in the direction of the small triangle of the battery.

   Note: On Bluetooth chargers, DMA-IBASE-BT-01 and DMA-IBASE-BT-02 battery charging is not available.

   Note:

   When you are charging the auxiliary battery, the base station’s spare battery status indicator displays either charging in progress (RED) or fully charged (GREEN).

WARNING: Dispose of the used battery promptly. Keep it away from children. Do not disassemble and do not burn it. Use the appropriate separate take-back systems for battery disposal.
