Since my GPS clock Garmin Forerunner 305 after 1.5 -. "Weak battery" reported 2 hours, I was looking for an inexpensive solution to the problem. On the Internet I found a guide to changing the batteries, which made a rather complicated impression. The hardest part was the "cutting" of the clock, since the housing is bonded. Since completely the ordered battery like the original, the real exchange was described more easily than in the manual. Soldering must be, however, can. Finally close with silicone adhesive. Function now far beyond the specified Garmin 10 hours out.
