[Elecraft] Lead-acid battery question

[k3hx at juno.com]

I use a change-out (every 3 years) automotive battery and the
Harbor Freight 42292 float charger on a venerable 3KW Onan
generator.  Good service, as the generator never fails to start even after many years. 
The box claims the 42292 will deal with flooded cell or sealed
lead-acid batteries.  My experience with this charger is limited
to flooded, automotive and "RV" deep-cycle batteries.

Our radio club's (NHARC.ORG) trustee keeps a trio of AGM deep cycle batteries happy between field days with the Battery Tender
system as mentioned by another poster.  

72,

Tim
