In Lab RCA: Battery didn't got charged even when connected to the charger.
Sensor replaced on 06/07, went down again on 06/09, data analysis shows the following:
Signal Strength looks good, battery is trending down rapidly and not charging
07/11 On Site Analysis:
battery was visibly puffed up. ended up replacing battery and solar panel.
Battery was dead also but it charged in the lab.
Sensor data has repeatedly been noisy. On site visit on 11/09 did not reveal any visible sign of what might be causing the noise. Nothing was obstructing the sensor and there was no grass or spiderwebs inside the pipe. Need to observe and understand this issue further.
sensor removed on 02/15

Fixes/Action: In conclusion, sensor appears to have gone down due to the battery dying completely and being unable to retain charge from solar panel. The reason behind this seems to be the battery just being out in the field for about two years and going through its natural battery life cycle. Need to track about how long after being out in the field, batteries stop being functional to try to get ahead of sensors going down due to faulty old batteries.
