Finally did the "djbahool battery conversion".
The new battery: (3.7V 370mAh 502530 lipo)

Did not make…
Why has Garmin been so conspicuously silent on this?
Well, seems the only big issue for this great device is solved now.
I replaced the original (4x20x28) Li-ion battery to a bigger (5x25x30) Li-polimer battery.
First testdrive was today:
AVG temp: 6 C
…It's been working great for me for the past month, although it's been warmer weather and I haven't gone on rides longer than four hours. Battery indicator (even w/ ConnectIQ battery apps) always reads 80%. Page up/down buttons aren't as crisp as they used to be.
GPS is on. I have tried another reset.
There is no EPO.BIN file in the folder so maybe that is the issue.
I had the same issue. I someone else suggested pulling the board back out and bending up the copper connectors to the GPS antenna and that seemed to work (for now at least)
Thanks for the reply and suggestion.
It worked !!!! My unit is working again. Thank you so much. I am so happy.
No device can really measure capacity. They measure voltage and infer capacity from that. Fully charged would be the same voltage no matter the size of the battery. I'd absolutely remove from charging the moment it shows as fully charged.
It is hard on these batteries to fully charge and fully discharge, just like with a cell phone. If you kept between about 40% and 70% charged you would maximize battery life but not get to use all the capacity. To get the capacity in the least damaging way, fully charge right before use. Remove from charge the moment it is fully charged, or sooner if you don't need all the capacity that day. Long term storage at 50-60% is best.
Try as I might, I could not get the side or bottom buttons to work with my larger battery, and cranking down on the screws didn't seem like a good idea as the board was already making indents into the foil pouch battery, so I ordered a 402530 battery (my 502530 measured 4.84mm at its thickest).
After dealing with Battery and Download issues from 2015-2021, on three different Edge 130’s, I caved. Bought an Element Bolt. Cold - no problem. Heat-no problem. 9hr ride-no problem. Should have bought one years ago.
