Yes, I have photos of the battery.
Batteries do not work, have deteriorated.
I gave in for repair, replacement cells.
Now there's another question.
Gave to repair the charger.
Before the repair, when the battery is installed, the light blinked very often (Mode: Replace Battery).
After the repair, they replaced the transistor to the more powerful (700V).
Now, when installing the battery, the light blinks twice (Mode: Problems in the electrical network).
Interestingly, that will show after installing new batteries.
But, it will be after 4 days (replacement cells).
