Starting power of lithium-ion batteries at low temperatures
503021-01
Lithium-ion batteries are far lighter than lead batteries, have a low self-discharge rate, and have more starting
power at temperatures over 15 °C (60 °F). At low temperatures, however, the starting power of lithium-ion batte-
ries drops to below that of lead batteries.
Multiple starting attempts may be needed. Press the start button for 5 seconds, and wait 30 seconds between
attempts. The pauses are necessary so that the heat created can distribute through the lithium-ion battery and
the lithium-ion battery is not damaged.
If the charged lithium-ion battery is unable to actuate the starter motor or does so only weakly when temperatures
are below 15 °C (60 °F), 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.
