after I drive the car I put the battery tender on. is it normal if it takes awhile for the battery to be fullycharged

How long does it take?Also can depend on your battery health and type of tender.Mine takes about 15 minutes using a CTEK 3300 on a Sears Diehard Platinum.

sometimes it takes an hr! Sometimes less. I was getting hard starts when the car sits fuel pressure checks out. I left the tender on all week and the car fired right up!! If I leave the tender on only for a day it wont fire right up? The battery is fairly new but I dont know how long the car was sitting at the dealer for

Battery tenders/Trickle chargers (1.5-2 amp charge) will take up to 34hrs to fully charge a battery.

315-550CCA=14.5-18.5 hrs @2 amps
550-1000CCA=18.5-34 hrs @2 amps

315-550CCA=3.5-4.5 hrs @8 amps
550-1000CCA=4.5-8.75 hrs @8 amps

315-550CCA=3-3.25 hrs @10 amps
550-1000CCA=3.25-7 hrs @10 amps

I would charge the battery all the way and have it tested. sounds like its bad even if its newer. also if it is a serviceable battery add distilled water to top it off.

Well ever since I have been using my battery tender my hard starts have disappeared! Car had a new battery in it already.. but keeping it fully charged has solved my problem!! :-)
