My car was left at a car shop with 3% battery left, making the 12v battery uncharged. Now I need to jump-start my car before running it, since the doors won't open due to the 12v battery losing its power. When checked, the SOC and SOH are still at 98%. Even after charging the 12v battery using an external 12v charger, the batery won't store power and will be losing power after 1 or 2 hours.
