Votage Readings

Using a standard Digital Voltmeter, the following voltage

readings will be obtained from a fully charged battery:

Pin 1 to Pin 4 = 7.0 VDC (± depending on polarity of leads)

Pin 5 to Pin 7 = 7.0 VDC (± depending on polarity of leads)

Pin 5 to Pin 6 = 7.0 VDC (± depending on polarity of leads)

Pin 6 to Pin 7 = 0.0 VDC

NOTE: The battery packs have three (3) contacts on one end

and four (4) contacts on the other end. Holding the battery pack

with the contacts towards you, the contacts are numbered from

left-to-right.
