Last week they installed new battery in my DS7 e-tense 4x4 under GK8 recall.
New battery has part code 6503794480. It seems like the new one has bigger capacity as old one. When dropped car to the garage, full charge range was about 54 km. After first full charge after replacement it shows 68 km range. Also total energy increased from 11.12 kWh to 12.22 kWh as shown by charger. My feel is that new battery is not charging as hard with recuperation as old one. So for now, not bad for car which has 5 years.
Provide this information (0-100%) after several charges. It’s always different at the beginning.
The old traction battery has a capacity of 13.2 kWh, but about 15% was reserved for hybrid driving.
