    I have a 2017 Prius Prime Advance, which I parked at my friend's home since mid Feb 2021, while I went overseas for family emergency. I am returning next week and has asked my friend to start the car. He started the car but nothing happens. He put in his small Li-Ion battery charger tool and said that the dashboard lights up but nothing is displayed. He put in the battery charger tool for 5 minutes or so.

    I am thinking that my friend will probably have to put his charger tool on the 12V Prius batter for at least an hour, so that it gets charged. He also has an SUV and said he has jumper cables and can try through that.

    Do you guys think this is still a battery issue and needs to get recharged by AAA or by SUV or is there something else that got drained.

    I did put in the fuel stabilizer as per the direction into the gas tank, before leaving the car in Feb 2021.

    Anyone with previous such experience of long parking will immensely help.

    You can try charging the 12v battery but it might be too late to revive it. Search the forum. You’re not alone. Next time invest in a maintainer or similar.

    Thanks Schja01.... Will replacing the 12V battery solve this problem. I have read a lots of threads but nothing is clear on the final solution. Some people said that a dead traction battery means nothing will start. So I still am looking for an answer. I will start with charging the 12V.

    Yes, the engine won't start with a dead traction battery, but 5 months is too short a time for it to self-discharge to that point. Even when the battery looks dead from what the driver displays show, there is still energy in the pack.

    Thanks Trollbait, we will try to jump start the 12V and see what happens.
