#Battery vampire drain.
“1% every day!”
We all know that Li-Ion battery do not like to be fully charged or fully discharged and perform best at around 40 - 60% SOC. Every battery has a normal discharge rate even when is not used, but knowing that I still did not expect to find my car traction battery completely drained today.
The car lost while parked for 10 days around 10% battery capacity and 3,6 Ah.
Li-Ion cells do not like low voltage < 3.5V. A totally drain battery could permanently destroy the cells so, be very careful if you do not plan to drive for more then a week or an even longer period of time and charge the battery before that.
“Charge the car to 60 - 70% (11 bars) every month !”
