maintain voltage longer in storage. However, the environment the batteries reside in for the 10 years can
deplete the power.
We suggest name brand Alkaline batteries for
indoor displays
.
A minimum voltage of 1.48V for each battery is necessary for proper performance.
Use batteries dated at least six years in advance of the current year. Batteries dated earlier than six
years from now may still work, but may be unstable in performance.
Good name brand batteries make less noise, which reduces the chance of RF (radio frequency)
interference from the battery compartment.
