How to Replace a Battery in an ALTA Industrial Sensor

ALTA Industrial Sensors use a single AA RAMWAY ER14505M 3.6V Industrial AA Lithium Thionyl Chloride, 1500mAh non-rechargeable battery. While these batteries generally offer enough voltage to operate the sensor for years, battery depletion can occur more rapidly due to configurations or environmental conditions. Find steps for replacing this battery in this article if it is depleted.

  1. Power off the sensor by pressing the power button for approximately three seconds until the button LED flashes red.
  2. Remove the sensor top by unscrewing the four top screws (#2 Phillips), then lift the lid up and off the enclosure base.
  3. The battery is shrink-wrapped and wired with a pin connector; grab the wire pair from the battery near the base of the connector and pull straight up and out firmly while pushing down on the foam inside the sensor enclosure.

  4. Place the lid back on the enclosure.
  5. Tighten the four machine screws using a #2 bit to 0.9 Nm / 7.9 in-lbs. Tighten each screw about 75%, then gradually tighten the rest of the way using a cross pattern over three or more loops.
