How can I replace the battery?

How can I replace the battery? The battery on my watch has become very unreliable lately. (Forerunner 405) It will die within 2 hours from the time I take it off the charger. How will I replace the battery myself, so I don't have to pay $70 and ship my watch to Garmin? Thanks for any help!

It is a soldered in battery - 3 milliA battery. This will requiring removing the back panel and unsoldering the old battery and resoldering in the new battery. I found a website that sells the battery for around 20 Euros (right under $30).

It is very difficult to replace the battery without damaging the seal ring.

You can get the batteries that have the right solder tabs on ebay. I tried one of the generic ones and they it only lasted for 4 hours even though they claimed extended run time. I ended up replacing it with the genuine Garmin battery from Route JD and it runs like new... more than 8:30.
