A few months ago a used Leikr watch was donated to me . The battery only lasted a bit over two hours. So i decided to modify the watch so new battery would fit. With the new battery i switched on watch and kept it with me with backlight on for 6.5 hours and only one stripe of powermeter was gone.
Removed cover and placed new battery
Cut out part of cover with lasercutter, but carefully with sharp knife wil work to. Printed new part for the backcover on my 3D printer that fits into the cutout part. This was needed to fit the 800mah battery that is slightly higher.
the proof of the extended battery life , as i said 6.5 hours ligt on and gps with map.
How did you snapped it opened? What was the original battery capacity? I might try this at home. Looks easy and I have a 3D printer to do it as well. I wonder if we can find a ring that will make the watch waterproof again.
PDM, what code/dimensions had the original battery? (I wonder whether the 330 mAh battery can be swapped against a one with a higher capacity but the same size, that is without modifications of the back.) Thanks.
pdm- I purchased the extended battery you referenced, and installed it into my Leikr. Now I need a modified backplate like the one you made. Is there any way I could pay you to make one for me? I don't have access to any of the tools required.
