Nissan LEAF 2023 Owners Manual
6.3.1. Li-ion battery available charge gauge
- (1)Low battery charge warning light illuminates in yellow when the available Li-ion battery charge is getting low.
- (2)This figure shows the current state of charge (%) of the Li-ion battery.
- (3)The gauge indicates the approximate remaining Li-ion battery charge available to run the vehicle.
Charge the Li-ion battery before the blue bar of the gauge (1) disappears.
When the low battery charge warning light 
illuminates in yellow, charge as soon as it is convenient, preferably before the blue bar of the gauge (1) disappears. When the blue bar disappears and the low battery charge light illuminates in yellow, there is a very small reserve of Li-ion battery charge remaining.
The length of the blue bar of the gauge is determined by the available charge and the amount of charge the Li-ion battery is capable of storing at the current temperature.
Temperature affects the amount of charge the Li-ion battery is capable of storing. The Li-ion battery is capable of storing less power when the Li-ion battery temperature is cold. The Li-ion battery is capable of storing more power when the Li-ion battery is warm. The length of the blue bar of the gauge can change based on the amount of power the Li-ion battery is capable of storing. For example, when the Li-ion battery becomes colder, a longer blue bar is shown because the available charge is a greater percentage of the Li-ion battery's capability of storing power. When the Li-ion battery becomes warmer, a shorter blue bar is shown because the remaining energy is a lower percentage of the Li-ion battery's capability of storing power.
