I imagine that old batteries can be charged but can't hold the charge when removed from the charger? Maybe a leak/breakdown insulation that quickly bleeds the charge off??? or the electrolyte has outlived its usefulness?
I think the batteries are going bad. what do you think? They come with a 3-year guarantee so I guess they have outlived themselves.

Frank, That's how the charger works. They have to boot up before taking a reading of your charge. Your batteries are too young to die unless you have damaged them with a fast charge.
