Nope, 17.5 hours is what it says on my information packet; and the lights go out when they're done charging and they went out @ about 17 hours last time so it's right. Other chargers w/ batteries were like $15+ for their kits, the Kodak kit w/ four AAs was $9.xx before taxes at Wal-Mart, so the charging time doesn't bother me at all.
