8 PREPARING FOR USE
If the charged lithium-ion battery does not or only weakly turns
over the electric starter when temperatures are below 15 °C
(60 °F), then the battery is not faulty, but needs to be warmed up
internally to increase its starting power (current output).
The starting power increases as the battery warms up.
