Battery Replacement HM-20

Where to find them:HM-20 batteries are no longer obtainable via the Solutionbee store, however, they can be purchased online via Amazon, etc.  Please search for "Tadiran TL-5930/f" for replacement batteries.  Make sure to select "/f" batteries as only that version includes the cable and connector that is attached to the battery and which is needed to attach to the HM-20.

How to install them: Please follow the step by step instructions described below to insert batteries in or remove batteries from your HM-20 Smart Hive Monitor device.

1. Prepare the Smart Hive Monitor for battery removal/insertion.

1. Remove the top stainless steel plate of the hive monitor.  Identify the two screws (and washers and nuts) that attach the electronic module to the frame bracket.

1. Remove the two bracket screws. The electronic module will now be free from the scale frame. Identify the four screws that hold the module together.

1. Remove the four module screws. Carefully open the module.

1. If you are replacing a battery, there will already be a battery in the module.  In this case, the battery is connected to the printed circuit board with a lock connector.  Pinch/press the connector to pull the male connector loose from the female connector on the printed circuit board. This operation may take some wiggling of the connector to remove it.

1. If you are simply inserting a battery, there won't be a battery in the module.

1. Place a battery between the two clips on the bottom portion. Make sure that the leads exiting the battery are in the 12 o'clock position.

1. Insert the battery lead male connector into to mating female connector on the printed circuit board.

1. Review your work. The assembly should look like in the following picture:

1. Close the module by lifting and then turning the printed circuit board portion of the module on top of the battery portion of the module. This will avoid the insulation O-ring from falling out of its groove.

1. Reinsert the four electronic module screws.

1. Reattach the electronic module to the scale frame bracket.

1. Reattach the top cover. You are done. Turn the power switch to the on – “I” position.  Try to communicate with the module with a smartphone as per the Installation Guide.
