Query: Great Phone - it worked well for us for over 2 years

My wife and I bought this phone in 2005 and it has been a great phone and answering machine for us. About 6 months ago the battery started dying on us quite regularly and it finally got to the point where you couldn't talk for more than about 10 minutes before it would die entirely. If we could have found a replacement battery for a decent price, we probably would have just replaced the battery, but it was actually cheaper to replace the entire unit with a similar AT&T handset (that we're also pretty happy with).
