Battery Pack Information
The following information relates to the care and handling of the Anritsu battery pack and Lithium-Ion
batteries in general.
• The battery pack supplied with the MS2721B may need charging before use. Before using the MS2721B,
the internal battery may be charged either in the MS2721B, using either the AC-DC Adapter or the
12-Volt DC adapter, or separately in the optional Dual Battery Charger.
• Use only Anritsu approved battery packs. Some non-approved battery packs will fit into the MS2721B,
but are electrically incompatible and will not charge correctly.
• Recharge the battery only in the MS2721B or in an Anritsu approved charger.
• When the MS2721B 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 to improve battery performance and battery life.
• The battery can be charged and discharged hundreds of times, but it will eventually wear out.
• The battery may need to be replaced when the operating time between charging becomes noticeably
shorter than normal.
• Never use a damaged or worn out charger or battery.
• Storing the battery in extreme hot or cold places will reduce the capacity and lifetime of the battery.
• Never short-circuit the battery terminals.
• Do not drop, mutilate or attempt to disassemble the battery.
• Do not dispose of batteries in a fire!
• Batteries must be recycled or disposed of properly. Do not place batteries in household garbage.
• Always use the battery for its intended purpose only.
