For a NEW HidrateSpark PRO (formerly STEEL) bottle, you first must remove the Sensor Puck on the bottom of the bottle to fully charge the battery by turning the bottle upside down and screwing the puck counter clockwise to the body. Then place the puck on a flat surface and attach the magnetic end of the HidrateSpark charging cable to the puck. While charging every other LED on your puck will illuminate and fade in / out (every 10 sec.) green. Once fully charged every other LED on your puck will remain SOLID GREEN. It may take up to a few hours to charge the bottle.
To assemble the puck to the body after charging, turn the bottle upside down and screw in the puck clockwise to the body. Make sure the puck is fully assembled and secured to the body to ensure accurate readings.
DO NOT overload or squeeze the sensor puck as it can damage internal electronics.
Each time upon sensor puck reassembly, we recommend recalibrating your sensor within the app.
NOTE: Please avoid putting the charging cable near metal surfaces when it's not in use. If the cable comes close enough to a metal surface, it may connect to that surface with its magnets and cause damage to the cable
