Batteries 3,9 or 12 volts

 

 

The majority of LiftMaster Security+ 2.0 remote controls operate using 3-volt lithium batteries. These batteries are available in two different models: the CR2016 and the CR2032.

While older residential remote controls may have required 12-volt batteries, these are now less common and are typically used for remotes designed for commercial door openers.

Exterior keypads and some remote controls that are not manufactured by LiftMaster, Chamberlain, or sears typically operate using nine-volt batteries.

 

The best place to buy these batteries are stores like cvs, staples and Walgreens
