Spice Series
Battery
HP 82109A (2 x AA 700mah) The Spice battery pack consists of 2 AA NiCd batteries providing 2.5 volts. The keying on this pack is subtle but important. The area under the recycle logo is flat, but on the other side of the pack, there is no flat bar between the batteries. A ridge in the battery compartment assures that the pack is installed correctly. Radio Shack "Replace-A-Cell" (cat. no. 23-191) batteries are said to work well as replacements.
Chargers
HP82090B (Europe, 220V) : Open Circuit Voltage = 10.26V, R(int) = 14.34 Ohms
