Igor Vysoc you did not tell us if you removed those boards. If you did, post some pictures of those with your QUESTION. Adding images to an existing question
It is always best to remove and to properly clean everything with some high grade isopropyl alcohol. For a proper cleaning, use this guide. Repairing iPhone Liquid Damage It was written for a Apple iPhone 3G but it is still pertinent to your mouse as well. Truly assess the damage. Look for major corrosion, evaluate the pins in the connectors etc,. Take a look at all connectors as well as cable ends. Once properly cleaned, REPLACE THE BATTERY and reassemble to re-evaluate.

Thanks for suggestions. I did everything: remove all boards completely, cleaned all visible spots that possibly from water. But I have used CRC brand QD Electronic Cleaner. My concern about lithium battery. Its label says 4.2V, but can be charged up to 4.1V only.
Do I need to replace it? Again, regardless how long I am charging - red light (mouse indicator) always present, not green.

Igor Vysoc that voltage is ok. But it is not enough to test the voltage to prove that the battery is okay. If it got wet etc, I would replace it as well.
