6. Stationary Battery Committee
What I/We Have Learned
Charge Controller Critical
Prevents Summer Overcharge and Winter OverDischarge
Not All Charge Controllers Have LVDs
Very Critical for Lead-Acid, Especially VRLA
Finish Charge Important in Summer to Clear Sulfation
VRLAs Better than Flooded for PSOC?
Flooded with Antimony (including Selenium) Work OK
Tubular Gel VRLA Best Lead Acid

7. Stationary Battery Committee
OverDischarge
Kills Lead-Acid Batteries
Ni-Cd is Better Option

8. Options for Lengthening Battery Life
Upsize Batteries on Standalone
Turn on Hybrid Grid or Higher Voltage
% DOD for most battery types not
@ same % voltage
drop
