55  Charging and caring for batteries

■

Before using a Li-ion battery, read the Li-ion Bat-

tery Safety Information (MPC-00006-xx) included 

with your battery, and follow the instructions it pro-

vides. Incorrect use of a Li-ion battery can cause 

explosion or fire.

■

Do not short-circuit the battery contacts, neither 

intentionally nor accidentally, e.g. by placing the 

battery with conductive materials such as keys or 

jewelry inside a pocket or container. Short-circuit-

ing the battery contacts can heat up the conduc-

tive material.

■

Do not obstruct the vent hole(s) on the battery. 

If the vent on the battery is obstructed the battery 

may explode, causing personal injury and/or 

equipment damage. If the vent on the radio is 

obstructed, audio quality and/or key function may 

deteriorate and radio seals may be damaged.

Notice  Turn the radio off before removing the battery, 

and turn it on again after attaching the battery. This 

ensures that the radio powers down and up correctly. 

Failing to follow this procedure may require the radio 

to be turned off then on again to operate correctly.

Charging temperatures

Notice  Do not expose a battery to very high or very 

low temperatures for extended periods of time. Doing 

so will shorten the usable life (‘service life’) of the 

battery.

To achieve the best results when charging your 

battery:

■

Before you begin to charge your 

battery, make sure that the battery 

temperature is close to the room 

temperature in which the battery is 

to be charged.

■

If possible, charge the battery in 

temperatures between 50 °F 

and 77 °F (between 10 °C  and  25 °C).
