Terminal Contacts Gently swab the contacts with alcohol or contact cleaner to remove the dirt. It is
important that the exposed contacts of the battery stay clean and unbent.

provider.
CAUTION
Avoid touching the contacts of the battery and the recessed area on the terminal.
Finger oils tarnish contacts, causing bad connections. When operating on battery
power and experiencing a high occurrence of bad or incomplete data transfers,
clean the contacts.
