I've erased error code "P0A80" more than 10 times after "Check hybrid system" alerts, is it safe?

    After "check hybrid system" alerts, I've erased error code "P0A80(Replace Hybrid Battery Pack)" for over 10 times using OBDII. The alert "check hybrid system" came up suddenly almost weekly. Can I still erase the code again and again? Will there be any future problems? Should I replace hybrid battery pack as soon as possible?

    Thanks~

    It will be safe until it is not.
    Have I seen electolyte has vented and leave a nasty resisue? Yes.
    Have I seen small fires? Yes.
    Are either of these guaranteed to happen to everyone? No.
    So I guess the question is how lucky do you feel?

    Batteries fail in different ways.
    Internal short leaky electrolyte, corroded terminals, voltage imbalance, low capacity, high resistance, etc

    No one can tell without seeing more info or data how exactly yours has failed.

    Your car is telling you there is a problem. Ignoring it will not fix it. You will need to deal with the battery in some way.

    Hopefully you aren't doing more damage, but you might be.

    Is there anyone nearby with tools that can extract more data about the hybrid battery? (Voltage of modules, internal resistance, etc)

    Or can you work on the batty yourself to open it up an inspect it?
