Garmin OEM Replacement Battery Forerunner 405, 405cx and 410 (PD3048 Li-ion)

It took about an hour to replace the battery in my Garmin 410 after watching a few online tutorials, but I did it and it works once more! The battery lasts a long time and seems just as good as new. No complaints at all, very satisfied. For replacing the battery on the 410, you need to have some basic soldering skills; it took me quite a while to get it right. If you don't know how to solder, you can buy a kit here pretty cheaply and practice a bit before you do that change. It's probably worth it for a $400+ watch.If you have any questions, just ask in the comments and I'll try and respond promptly.

I bought this to replace the battery in my 7-year-old Garmin Forerunner 405 hoping to bring it back to life as some of the other reviews reported it did for theirs. When I received it, I noticed it did not have the required markings that the Genuine Garmin battery should have according to Garmin's website. We still decided to try it out. My husband spent over 2 hours soldering the new battery in. After replacing the battery and charging the watch up, I took it right off the charger and went for an 18 mile training run. Toward the end of my 3-hour run, it started alerting me of low battery. Sorry to say I was disappointed for wasting my time and money.

Battery came in a timely manner but just a heads up, you need someone who can specially install a new battery. A watch store cannot install it as you need some soldering done.

The new battery worked like a charm. I installed it following video instructions that I Googled. Soldering the leads to the battery can be a bit tricky if you haven't soldered much lately. Be sure to have flux on hand to make the job easier. Dab a little on the leads attached to the battery to help the solder along. Looking forward to a few more years of running with my revitalized Garmin.

I spent nearly an hour replacing the battery, only to find that the new one was also giving a "low battery" signal. Rather than go through the hassle of replacing it again (Garmin won't do it for you), I threw both the watch and battery away, and replaced it with the Tom Tom Runner, which cost half as much but works much better

It took about 3 weeks for us to receive this product. It was not worth the wait.

Non-traditional replacement process but fairly easy to accomplish with appropriate tools and regained the original performance of the watch. Recommended for those able to tackle the replacement procedure.

Good product delivered on time.
