Battery Terminal Corrosion
The more batteries you have, the more terminals/connectors you have, and greater issues with connector corrosion. As an example: Lots of terminals

Terminal corrosion is due to battery gassing and doesn't have anything to do with the number of connecting items. If you keep your batteries cleaned and terminals coated you should have a minimum of corrosion. Don't let them get low on water and top off only when they are fully charged.
