Approved Batteries Only • Always use the battery only for its intended purpose. • Use only Anritsu-approved battery packs. Some non-approved battery packs may fit into the VNA Master but are electrically incompatible and will not charge correctly. • The battery can be charged and discharged hundreds of times, but it will eventually wear out.
Page 84: Recharging
• The battery can also be charged separately in the optional Dual Battery Charger. • Recharge the battery only in the VNA Master or in an Anritsu-approved charger. • Do not charge batteries for longer than 24 hours. Overcharging may shorten battery life.
