Battery Pack Information

The following information relates to the care and handling of the Anritsu 633-44 battery pack and Lithium-Ion
batteries in general.
• The 633-44 battery pack supplied with the MS2723B or MS2724B may need charging before use. Before
using the Spectrum Master, the internal battery may be charged in the Spectrum Master, using either
the AC-DC Adapter (40-168-R) or the 12 Volt DC adapter (806-141), or may be charged separately in the
optional Dual Battery Charger (2000-1374).
• Use only Anritsu approved battery packs. Some non-approved battery packs will fit into the MS2723B or
MS2724B, but are electrically incompatible and will not charge correctly.
• Recharge the battery only in the MS2723B or MS2724B or in an Anritsu approved charger.
• When the Spectrum Master or the charger is not in use, disconnect it from the power source.
• Do not charge batteries for longer than 24 hours. Overcharging may shorten battery life.
• If left unused, a fully charged battery will discharge itself over time.
• Temperature extremes affect the ability of the battery to charge. Allow the battery to cool down or warm
up as necessary before use or charging.
• Discharge the battery from time to time in order to improve battery performance and battery life.
• The battery can be charged and discharged hundreds of times, but it will eventually wear out.
