No action required, the battery is operating
correctly. The Pilot-12 Lite and Pilot-24 Lite
are 12V and 24V backup batteries respectively.
You may hear coil whine (a faint buzzing
sound) in later stages of charging if the battery
is charging on lower voltages or on a lower
wattage.
The Pilot-12 Lite and Pilot-24 Lite heat up
during regular portable usage.
On more demanding configurations such as
those with high pressures, enabled humidifier
and heated tubing, may cause the battery to
heat up past optimal charging temperatures.
Built-in features to maximize cell life will
prevent the battery from charging in this state.
Please allow the battery to cool down for 10-
20min and try charging your battery again.
