Charging and Discharging, Storage
• The full performance of a new batteries is achieved only after two or three
complete charge and discharge cycles.
• The batteries can be charged and discharged hundreds of times, but they will
eventually wear out. Contact VTech if you need to replace the batteries.
• If left unused, a fully charged battery will lose its charge over time.
•
Use the batteries only for their intended purpose. Do not short-circuit the
batteries. Short-circuiting the terminals may damage the batteries or the
connecting object. Do not use a damaged charger or battery. Using a
damaged battery may cause it to explode.
• Do not place or store the batteries, inside or outside the microphone, in the
immediate vicinity of open fire or other heat sources.
• Leaving the batteries in hot or cold places will reduce their capacity and
lifetime. Charge batteries within an ambient temperature range of +5° C to
+40° C (+41° F to +104° F), max. humidity 85%. A device with a hot or cold
battery may not work temporarily, even when the battery is fully charged.
• Avoid overcharging. Repeated overcharging can lead to deterioration in
batteries performance. Never attempt charging the batteries with reversed
polarity as this may cause the gas pressure inside the batteries to rise and
lead to leakages.
• Remove batteries if storing product for more than 1 month.
• Store batteries in a cool, dry place without corrosive gases. Temperature
range for storage of charged batteries up to 6 months: -20° C to +45° C
(-4° F to 113° F); up to 2 years: -20° C to +35° C (-4° F to 95° F); humidity
65±20%. Discharge and charge batteries every 3 months.
