I would put the lifespan somewhere closer to 2-3 years if you expect to maintain close to the original charge capacity, with 5 being on the outside or "lucky" realm.
I've NEVER had a lithium battery last longer than 3-4 years without starting to lose charge capacity. Ever. And general testing of lithium battery technology bears this out.
