Replacing compact tracker batteries

This section explains the steps to replace the batteries of compact trackers (ATEX/IECEX, non-ATEX).

Pre-requisites​

Ensure you have the correct batteries for your compact tracker. The required batteries are 3x 3.6V AA size bobbin Cell Li-SOCl2 (UL1642 or IEC 60086-4 certified). The recommended battery models are :

  • For non-ATEX products: SAFT (LS14500), EVE (ER14505) or Tadiran (ER14505)
  • For ATEX products: the RAMWAY ER14505 battery (IEC 60079-11 certified)

Step 1: Open the compact tracker casing​

Please perform the battery replacement in a safe zone outside any hazardous area.

Open the compact tracker casing screws which are located as shown in the picture below. The screw driver should be of type CR-V T10 and the screw torque force should be in range (0.51 - 0.53 Nm).

Step 2: Insert the batteries​

After opening the casing, remove the 3 batteries and insert the 3 new batteries with the correct polarity as indicated on the attached label. The 3 batteries are connected in parallel with the same orientation. Do not mixed old and new batteries.

Step 3: Reset the power consumption in firmware and the backend​

Once the new batteries are inserted into the tracker, the device should automatically join the LoRaWAN network. Follow the instructions here to reset the battery status in firmware and ThingPark location backend.

Step 4: Close the casing​

Once the new batteries are replaced and the device is communicating, close the casing ensuring that the label is well folded and the rubber gasket is properly positioned. The torque on the screws should not exceed 1.2Nm.

Note
  • There is safety sticker inside the casing. It should never be removed.
  • The batteries must be replaced outside non-hazardous (non-ATEX) area.
  • The battery models above are not rechargeable and batteries should not be attempted to recharge.
  • All the new batteries should be from the same batch.
  • The old and new batteries should never be mixed.
  • The batteries should not be stored in optimum conditions if not used and might need to be depassivated if unused for few months. The depassivation can be done by connecting a 100 ohm resistor in pulses for a total of 30s.
  • Dispose of the old batteries in an appropriate recycling facility.
