Chapter 2: Set up a Battery Maintenance Routine

Introduction

The MX9 uses a 2400 mAh/2200mAh Low-temp battery. Minimum battery life is 500 charge/discharge cycles before
replacement.
Hand held devices and body worn devices use Lithium Ion (Li-Ion) main battery packs that are lightweight and relatively small.
Vehicle mounted mobile devices and vehicle mounted cradles/docks are powered by the vehicle battery.

Extending Battery Life

The life and capacity of a Lithium Ion battery pack can vary significantly depending on the discharge current and the
environment in which it is used. Li-Ion battery packs do not need to be fully discharged between charge cycles.
Regardless of the type of battery being used, following are suggestions for extending battery life:
Immediately replace batteries in mobile devices with the appropriate, fully charged battery when equipment battery
l
warnings are issued, heard or displayed.
Fully charge a new battery before using.
l
Remove batteries from unused units or units that will be unused longer than a day.
l
Place discharged batteries in a battery charger as soon as possible.
l
Store batteries in locations that maintain an ambient temperature of approximately 25°C (77°F).
l
Recycle defective, shorted or end-of-life batteries.
l
Any Lithium-Ion battery that is over a year old is considered an old battery.
l
Replace all batteries more than a year old with new batteries.
l
To determine the age of the battery, check the battery label that shows the manufacturer ship date. The ship date has the year
and the month that the battery was shipped. The first field (labeled 1-0) is the year the battery was shipped. The second field
(labeled J, F, M, A, etc.) is the month. So if the 8 and the F are punched out, the battery was shipped in February of 2008.
To determine the actual shipping date, use the serial number on the battery label to determine the ship date. Contact
Assistance
for help if needed.

Self-Discharge

Batteries should be stored at temperatures close to 25°C (77°F) because higher temperatures cause batteries to self discharge
faster than lower temperatures.
All batteries begin self-discharging after receiving a charge. The rate at which the battery self discharges depends on the
battery construction, temperature, initial capacity of the battery, and the amount of time that has passed since the battery was
charged.
Note:
Temperatures significantly above 25ºC (77ºF) increase the self-discharge rate of all batteries.
