extended absorption followup / random pics

I last watered the batteries on Sept 18th and noticed no appreciable increase in water consumption.  I watered the batts again yesterday, and after six weeks water consumption was normal once again.  And this is after being in full sun in the interim. I am ready to recommend the eternal absorption approach a success for

Pb charging: absorption finishing amps and state of health

tracking  endAmps The Absorption stage of lead-chemistry battery charging is characterized by constant voltage (Vabs) and decreasing current.  The battery takes less and less current as it approaches full charge, and finally plateaus at a low rate.  Current is the red line in this graphic: That leveled off terminal rate in the right third is called endAmps,

in praise of the single Battle Born lithium battery

I have ranted elsewhere that buying too much lithium battery bank is a self-limiting behavior due to prohibitive cost.    I may have been wrong — I have seen lots of people running (or planning to run) multiple Battle Born batteries at $1000 per BB. Holy crap, y’all.  That’s real money.
