4 BATTERIES
The P5400 series portable radios use rechargeable, recyclable Nickel Cadmium (NiCd), Nickel Metal
Hydride (NiMH), or Lithium Ion (Li Ion) batteries. Please follow the directions below to maximize the
useful life of each type of battery.
Do not disassemble or modify Lithium Ion battery packs. The Lithium Ion battery packs
are equipped with built-in safety and protection features. Should these features be
disabled or tampered with in any way, the battery pack can leak acid, overheat, emit
smoke, burst, and/or, ignite.
If the battery is ruptured or is leaking electrolyte that results in skin or eye contact with
the electrolyte, immediately flush the affected area with water. If the battery electrolyte
gets in the eyes, flush with water for 15 minutes and consult a physician immediately.
4.1 CONDITIONING BATTERY PACKS
4.1.1 Conditioning NiMH Battery Packs
Condition a new NiMH battery before putting into use. This also applies to rechargeable NiMH batteries
that have been stored for long periods (weeks, months, or longer). Conditioning requires fully charging
and fully discharging the battery three (3) times using the tri-chemistry charger. The first time the battery
is put into the charger, this unit will condition Nickel-based battery packs by automatically charging and
discharging (cycling) the battery. Refer to the appropriate charger manual for details.
CAUTION
Failure to properly condition NiMH battery packs before initial use will result in
shortened performance by the battery.
4.1.2 Conditioning NiCD Battery Packs
A new NiCD battery does not require conditioning before use. However, M/A-COM recommends
periodically conditioning NiCD batteries to avoid the memory effect which results when a NiCD battery
is repeatedly charged and not fully discharged, further resulting in a lower voltage and a lower capacity.
Fortunately, both nominal voltage and capacity are restored through battery conditioning.
Conditioning requires fully charging and fully discharging the battery three (3) times using the tri-
chemistry charger. The first time the battery is put into the charger, this unit will condition Nickel-based
battery packs by automatically charging and discharging (cycling) the battery. Refer to the appropriate
charger manual for details.
