BATTERY INFORMATION
Battery Care and Tips
This product is powered by a nickel-metal-
hydride (NiMH) or lithium-ion rechargeable
battery.
The following battery tips will help you obtain the
highest performance and longest cycle life from
your Motorola rechargeable battery.
• Charge your new battery overnight (14-16 hrs)
before using it to obtain maximum battery
capacity and performance.
• Charging in non-Motorola equipment may lead
to battery damage and void the battery warranty.
• When charging a battery that is attached to the
radio, turn the radio off to ensure a full charge.
• The battery should be at about 25°C (room
temperature) whenever possible. Charging a
cold battery (below 10°C) may result in leakage
of electrolyte and ultimately, in failure of the
battery.
• Charging a hot battery (above 35°C) results in
reduced discharge capacity, affecting the
performance of the radio. Motorola rapid-rate
battery chargers contain a temperature-sensing
circuit to ensure that the battery is charged
within these temperature limits.
• New batteries can be stored up to two years
without significant cycle loss. Store new/unused
batteries in a cool dry area.
• Batteries which have been in storage should be
charged overnight.
• Do not return fully charged batteries to the
charger for an “extra boost”. This action will
significantly reduce cycle life.
• Do not leave your radio and battery in the
charger when not charging. Continuous charging
will shorten battery life. (Do not use your charger
as a radio stand.)
• For optimum battery life and operation use only
Motorola brand chargers. They were designed to
operate as an integrated energy system.

Recycling or Disposal of Batteries
Motorola endorses and encourages the recycling
of all re-chargeable batteries. Contact your local
Motorola dealer for further information.
Charging the Battery
If a battery is new, or its charge level is very low,
indicated by high pitched warning tones, you will
need to charge the battery before you can use it
in your radio.
Note: Batteries are shipped uncharged from the
factory. New batteries could prematurely
indicate full charge, charge a new battery for
14-16 hrs before initial use.
1. Place the radio with the battery attached, or the
battery alone, in the charger.
2. The charger’s LED indicates the charging
progress.
Battery chargers will charge only the Motorola
authorized batteries listed below; other
batteries will not charge.
Charger LED Status
Red Battery is charging
Green Battery is fully charged
Flashing Red * Battery is unchargeable
