Hi I need some help. I have a tough solar G-5600A 3160 that I bought almost 10 years ago. Recently whenever I press the light button, instead of the screen light up for few seconds, it lighted up for split seconds and off, then the battery indicator (L, M, H) all start to flash. As I read from the manual it said it's recovery mode that indicated charge required but after few seconds of all the L, M, H flashing, it stops at H and show fully charged. Any idea guys? I changed battery once around two years ago.

Is there any where I can change battery for my g shock other than Marco. They quote and ask me to change the module which I think unnecessary...

Is it? Cause from what I search online forum usually normal watch shop reluctant to do it and ask to refer back to Marco.
