Thanks for the writeup
I have an "intelligent" charger (Accumate) that copes with sulphated batteries, it tries to charge at 12 volt - if no joy then short bursts at 18 volt - then bursts at 24 volt before deciding it's kaput (the idea is right even if I've got the voltages wrong )
The other I use is an old analog charger, it often managesto get a dead battery back to life as it's go no intelligence, it just trickles the power in. Often it's enough to register on the modern charger.
I've got RC charger and had thought of using that but not needed to resort to that - yet.
The tip about leaving it connected to a decent battery is new to me - thanks for the info
