Avoid storing a vehicle in temperatures below −13°F (−25°C) for over 7 days. Avoid leaving your vehicle for over 14 days where the Li-ion battery available charge gauge reaches a zero or near zero (state of charge). Allow the vehicle and Li-ion battery to cool down after use before charging. Park/store your vehicle in cool locations out of direct sunlight and away from heat sources. Avoid sustained high battery temperatures (caused, for example, by exposure to very high ambient temperatures or extending highway driving with multiple quick charges). Use the normal charging or trickle charging methods to charge the Li-ion battery and minimize the use of pu...
