Looking to buy an affordable and practical external power source for jump-starting a battery. Any recommendations, guys? [pleading face]

The original battery in your Haima S5 from 2016, manual transmission, has been in use for six years. After being parked for half a month, you jump-started it with a power bank and have been driving it 50 kilometers daily for a week, but it still remains in a discharged state. If the car can't start after being off for more than an hour, it might be time to replace the battery.

Has anyone experienced a dead battery causing the anti-theft system to lock, and jump-starting didn't help?
