If a hybrid car's 12-volt battery (which powers the car's accessories) is dead, it may be possible to jump-start the car using a portable jump starter or another 12-volt power source. However, it's important to follow the specific instructions provided by the vehicle manufacturer to avoid damaging the hybrid system.
In most cases, it's best to have a hybrid car towed to a qualified repair facility if the 12-volt battery is dead or if there are any other problems with the car's electrical system.
