new battery, now plug light on

what had been a faithful battery (purchased in 98 from the punch out indicators on it ) died suddenly with no signs of getting progressivley weaker. It was working fine and then yesterday just would not turn the car over even with jumper cables to another car.
I bought a new battery. Now the glow plug light now blinks after start up.
Could I have had an existing glow plug problem before that only became evident with a fresh battery? I am confident I didn't get the posts backwards.
The engine spins faster before starting for sure but it wasnt hard to start before either.

Previous battery 750cca, new battery 850 cca
1979 300sd

Did you expect a postcard from your battery relling you that it was going to fail? That's the way most batteries die; quickly like yours did, probably from an internal short.

The GP indicator is telling you that there is a GP with an open circuit but it doesn't tell you which one. Do a search and you will find out how to do a resistance check to find the bad one. Then replace it. I suggest you buy 2 and carry a spare in glove box.
