“Low 12V Battery (#)”
1 chirp every
2 seconds
(none)
Charge 12V battery

warmed and/or charged more often.
B01 “Lockout (low 12V battery) (#)”

1 chirp per
minute
(none)
Check condition of 12V battery

battery may prematurely activate this notification, warm
battery and retest when appropriate. Replace battery as
needed.

activated in error if battery
charger is plugged into power source while lifter is
powered up. If so, power down lifter, disconnect charger
from power source, and power up again. If code persists,
check battery condition as directed above.
