    HP Probook430 G2 - LA-B171P no battery after water spill - How to check battery ?

    Hello.
    Have this HP Probook430 G2 - LA-B171P that after water spill stop to charging.
    It was 1 year ago. I dont find any corrosion on board, but it was previously in other shop. When i disassenbly it it miracly start to charge as on battery + i have 12.6V and orange charge light.

    But when i remove charger system dies. Voltage on +bat goes straight to 0V. i think it was cut out by battery ic, because when i open battery and charge it, it goes too quickly to 12,6V and after powering 12V 2,5W fan, voltage goes to 9V in 5minutes. So i think the cells is neardeath and its ic cutting voltage to prevent some damage.

    But how to prove it?
    Batmon show me that battery capacity is like new, but without charge. but this batmon reading i have with others bad batteries that after replace charge and work on battery.
