Battery recharging in solar keyboard doesn't work after water damage
I bought myself a wireless solar keyboard which worked perfectly until I poured some drink into it.
I dissasembled it and washed it in distilled water and isopropyl alcohol. Upon battery replacement, the keyboard worked well until the battery became flat.
In the photos is non-rechargeable batter cr2032, however the rechargeable had same results.
I am getting appropriate voltage from the solar cells but the rechargeable LED-indicator doesn't light up upon pressing the button and the battery eventually runs flat.
I am no pro in circuit board repairs, any suggestions will be appreciated.
