Not sure of Battery Tender Plus but the CTEK would be a good unit if you do not already have a charger. My E320 CDI's battery died last winter while in storage. Check the specs. of the battery tender to make sure it will charge a battery the size of the battery in the diesels you are using. The E320 CDI from 2005-6 use a 95Ah AGM battery.
