LITHIUM - Vanadium Pentoxide Rechargeable

Panasonic Vanadium Pentoxide (VL Type) rechargeable lithium batteries are compact, high energy secondary batteries that have nearly twice the energy of conventional button-shapedNi-Cd batteries.

Features:

One high-voltage battery can serve your backup needsCan provide the voltage equivalent of two or three 1.2VNi-Cd's or two capacitorsMonths of continuous use as a backupSelf discharge rate less than 2% a yearSuperior reliability; withstands overcharging and discharging

Applications:

ECRsMemory back-up in facsimilesMemory cardsPersonal computersSequencersTelephonesTunersVideo camerasVTRs
