Rec No.	Date	Loc From	Title	Loc To	Notes
6117	2022-11-30	Hill Slough Battery Bank	Maintenance	Hill Slough Battery Bank	Removed 3 older, flooded deep cycle batteries. Added 4 new-ish Duracell flooded, deep cycle batteries with 04/22 tags. We purchased these batteries to run the BA advection experiment April-Oct 2022.
6118	2022-07-13	Hill Slough Battery Bank	Maintenance	Hill Slough Battery Bank	We’ve been losing data overnight since mid-June, which is suspicious because the days are long and sunny. 2 batteries tested bad, 2 tested good, and 1 tested good but closer to weak. I removed the bad batteries from the system and wired up the 3 good ones. The good ones all needed water, about 3-4L each. We refilled them with DI water. I cleaned and sprayed all of the terminals.
5902	2022-04-20	Hill Slough Battery Bank	Maintenance	Hill Slough Battery Bank	There has been some power losses a couple weeks ago but okay for the last two weeks. All the screw terminals seemed tight. One of the battery terminals had some corrosion - all the terminals should be cleaned and sealed before winter.
5901	2021-03-11	Sherman Wetland-Temp1 Battery Bank	Installed	Hill Slough Battery Bank	We put the battery box from SW on the west side of the platform and installed the five group 31 flooded batteries from the SW temporary tower. The solar controller sn 11400080 and breakers from the SW temporary site were also installed in the battery box. The wiring is not optimal and should be cleaned up. Also because the drill battery died we could not mount the solar controller or bolt the battery box to the platform.
