Trying to charge an old iPhone (1st or 2nd) it has been dead for longer a year that I can imagine. How long will it take to charge, it has been on the red dead sign for an hour.
It won’t matter one wit how it was used. A 1st or 2nd gen iphone with original battery is just simply worn out. The battery will be 7-10 years old. No lithium battery retains useable charge over that lifetime, used or not, and regardless of how used when it was good.
And no device circuitry protects such an old battery - lithium batteries age and loose capacity from the moment they are assembled. Whether used or not, their lifespan is finite. A 6-7+ year old consumer electronics sized lithium cell is dead - used or not, stored or not and regardless of how used or how stored, they decay.

At that point there's a good chance that the battery is completely gone due to deep discharge. The circuitry should prevent it from getting to that point from use, but if it was drained all the way down to "0%" and then not charged for a year it's probably past the point (via self-discharge) where it will never recover.

I do understand that they age somewhat, but a properly maintained lithium-ion battery can still be useful if it was occasionally used to keep the charge in a certain range. I've got a few 7 year old lithium-ion batteries for a Canon dSLR that still work. Even some devices I have that were somewhat ignored still have working batteries, although it might take time to revive the battery. My 2005 iBook G4 1.42 still works on the original battery. It is somewhat degraded, but to be expected with about 250 cycles, 12+ years, and periods of time where it was put away and not charged. The info says it's around 60% battery health. Not great but still useful.
Hi
Leave for about 3 hours if it,s won't charge then battery is no good.
Cheers

Yes, but the op already said it’s not only an old model, but hasn’t been used in over a year. The odds that the op’s battery in that phone is going to take a charge now are as near to zero as one can get.
It depends on what condition the battery is in. It may charge up soon, or, if the battery is past its useful life, it may never charge.
If it is that old, it is highly unlikely it will ever take a charge again without a new battery
