Normal. Now put it in a museum and get a modern charger.
As long as that old charger works and you are not planning to keep it connected and operating 24/7/365, don't bother replacing with a "modern" charger. That old charger will outlast a dozen of the new "modern" ones plus it WILL work on a FLAT battery.
"Modern" chargers are designed to not charge if battery voltage is below 10V (IE "Flat")..
Got a flat car battery or tractor battery that sat over the winter?
Yep, that is where a modern charger will fall flat on it's face and you have to drag another charged battery to the dead one to trick the "smart" charger into charging.. That, is stupid to say the least..
You will not be able to pull my old school charger out of my dead cold hands.. Not even if you offered me 100 smart chargers.
That Transformer based old school charger is pretty much indestructible, rugged and reliable.
Just has one rule to remember, monitor progress and disconnect when done charging.. Pretty simple and works.
