| Battery Bank | |||||
| 2018-06-05 | BB-TA | BB-Fab | Removed | The site was shut down and the battery bank with action packer was removed for use at Vaira soil co2. | |
| 2003-02-13 | BB-VR | BB-Fab | Upgrade | Battery Bank Main | Added four batteries removed from Tonzi-Tower. Now a total of eight batteries. |
| 2003-12-19 | BB-VR | BB-Fab | Upgrade | Battery Bank Main | Cleaned battery terminals and added four batteries from the Floor site for a total of 12 at Vaira. |
| 2005-12-13 | BB-VR | BB-Fab | Upgrade | Six old gel cell batteries were removed and will be added to Tonzi Tower. Eight new gel cell batteries installed. The new batteries are Maxrate Premium Plus MT12-350. Valve regulated lead acid battery 12v 93 ah @ 20 hr rate. Bought from Nor-Cal Battery for 5 ea. | |
| 2022-05-10 | BB-VR | BB-Fab | Maintenance | Battery Bank Main | Fixed broken wire between the two banks of solar panels. Disconnected and load tested all the batteries. Two batteries, second from north in each box, tested bad. These were moved to the north most position and left disconnected. The other six tested good and were reconnected. |
| 2012-02-16 | BB-VR_soilco2 | BB-Fab | Installed | none | Initial installation of the VR_soilco2 battery bank. Two pairs of deep cycle batteries were installed for a 24V system. However the solar panels were only wired as 12V and bled the batteries dry. |
| 2012-03-19 | BB-VR_soilco2 | BB-Fab | Removed | The four new batteries for the soil CO2 sensors were completely dead (~2V). The batteries were wired for 24V but the solar panels were wired for 12V. Batteries removed. | |
| 2012-03-21 | BB-VR_soilco2 | BB-Fab | Installed | none | I installed new batteries (borrowed from DWR) for the new soil co2 system. The original batteries were killed because they were wired for 24V and the solar for 12V. |
| 2018-06-05 | BB-VR_soilco2 | BB-Fab | Replaced | The battery bank from Twitchell Alfalfa was installed to replace the original batteries here that had a catastrophic failure | |
| 2020-09-16 | BB-VR_soilco2 | BB-Fab | Maintenance | Battery Bank SoilCO2 | I checked the water in the soil co2 battery bank. The water levels were low exposing the plates but these batteries didn’t take that much water – about a gallon to fill all of them. |
