BATTERY MAINTENANCE
Lithium-Ion rechargeable batteries require
routine maintenance and care in their use and
handling. Read and follow the guidelines in this
document to safely use Lithium-Ion batteries and
achieve the maximum battery life span.
OVERVIEW
Do not leave batteries unused for extended
periods of time, either in the product or in storage.
When a battery has been unused for 6 months,
check the charge status and charge or dispose
of the battery as appropriate.
The typical estimated life of a Lithium-Ion
battery is about three years or ~500 charge
cycles, whichever occurs first. One charge cycle
is a period of use from fully charged, to fully
discharged, and fully recharged again. Use a
three-year life expectancy for batteries that do
not run through complete charge cycles.
Rechargeable Lithium-Ion batteries have a
limited life and will gradually lose their capacity
to hold a charge. This loss of capacity (aging)
is irreversible. As the battery loses capacity, the
length of time it will power the product (run time)
decreases.
Lithium-Ion batteries continue to slowly discharge
(self-discharge) when not in use or while in
storage. Routinely check the battery's charge
status.
Use only the provided battery(s) in your product.
Use only the provided charger to charge your
battery(s).
NOTE: The battery self-discharges during storage. Higher temperatures (above 20 °C or 68 °F) reduce the battery storage life.
NOTE: When you troubleshoot battery issues for dual battery configurations, test one battery and one battery slot at a time. A defective
battery can prevent the battery in the opposite slot from charging, leaving you with two uncharged batteries.
BATTERY MAINTENANCE
Observe and note the run time that a new fully-
charged battery provides for powering your
product. Use this new battery run time as a basis
to compare run times for older batteries. The run
time of your battery will vary depending on the
product's configuration and the applications that
you run.
Routinely check the battery's charge status.
Carefully monitor batteries that are approaching
the end of their estimated life.
Consider replacing the battery with a new one if
you note either of the following conditions:
•
The battery run time drops below about 80%
of the original run time.
•
The battery charge time increases
significantly.
If a battery is stored or otherwise unused for an
extended period, be sure to follow the storage
instructions in this document. If you do not follow
the instructions, and the battery has no charge
remaining when you check it, consider it to be
damaged. Do not attempt to recharge it or to use
it. Replace it with a new battery.
CHARGING
Always follow the charging instructions provided
with your product. Refer to your product's
user manual and/or online help for detailed
information about charging its battery.
Use only the provided charger to charge your
battery.
