WPS AccuMate Battery Charger - LS6/1.2

Using this to keep my car alive during 5-7-month absences. Works well, even with battery still attached to car's electrical system. Disconnecting battery not an option, as this erases all the computer memory and makes it impossible to have the car smog checked without first driving it for about 100 miles.

Have 8 of these and they work very well, keeping the battery charged when the cars are in storageHighly recommend.
