The DEKA / East Penn Automotive Computer Memory Saver prevents your electronic memory loss when replacing your battery, by means of plugging the adapter into the cigarette lighter, then connecting the clamps to a bypass battery.

This product is intended for the use with a 9 volt battery (not included); or via attaching the clamps to a spare 12-volt battery.

Please note that all vehicles made in the year 2000 and beyond, require 10.5 volts to save the memory functions - in this case, use of the 9 volt battery would not be applicable.

*Wire length from clamps to cigarette lighter: 9 feet.
