BATTERIES
Batteries will degrade over time depending on temperature and usage. For best
performance, the batteries should be replaced every 3 years. Use only LiftMaster
part 29-NP712 for replacement batteries. The operator comes with two 7AH
batteries. Two 33AH (A12330SGLPK) with additional battery tray (K10-36183) may
be used in place of the 7AH batteries.
The batteries contain lead and need to be disposed of properly. Batteries do not
perform well in extremely cold temperatures.
NOTE: If your application includes a heater, two 33AH will not fit into the operator
enclosure.
The operator alarm will beep 3 times with a command if the battery is low.
