Lithium-Ion Battery Maintenance
Lithium-Ion Battery Maintenance
Lithium-Ion rechargeable batteries require routine maintenance and care in their
use and handling. Read and follow the information in this document to safely use
Lithium-Ion batteries and achieve the maximum battery life span.
Key Information Use only Tektronix-approved batteries in your Tektronix products.
Do not leave batteries unused for extended periods of time, either in the product
or in storage. When a battery has not been used for six 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 two to three years or
300 to 500 charge cycles, whichever occurs
fi rst. One charge cycle is a period
of use from fully charged, to fully discharged, and fully recharged again. Use a
two to 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. The product
user manual typically includes information on how to check battery status, as
well as battery charging instructions. The latest product manuals are available at
www.tektronix.com/manuals.
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 con
fi guration 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 signi fi cantly.
