Battery Replacement Policy
Summary
CenTrak devices are designed to work exclusively with authorized batteries purchased from CenTrak*.
All battery replacements for Tags, Monitors, Virtual Walls, and Exciters, must use the authorized
replacement battery listed in the CenTrak device catalog and can be obtained for your particular
devices from CenTrak sales representatives, account management, and the CenTrak Webstore at
centrakstore.com. CenTrak has obtained assurances from our manufacturers to ensure batteries will
meet the stringent requirements to properly operate all technical aspects of CenTrak devices.
Voiding of Warranty
Proper battery usage and replacement practices help ensure devices can continue to be covered by
the CenTrak warranty. Failure to comply will result in termination (voiding) of device warranty. Please
refer to the CenTrak Warranty for more detailed information.
Definition of an Unauthorized Battery
•Batteries purchased from sources other than CenTrak or a CenTrak Authorized Reseller, even if
the battery is the same brand and model as the authorized battery.
•Authorized batteries that did not follow proper battery storage guidelines or surpassed their
shelf-life expectancy.
•Mixing of new authorized batteries and unauthorized batteries for devices that utilize more than
one battery.
•Using different brand batteries in monitors than what came with the monitor, even if the battery
is authorized battery. Different brand batteries can be indicated by battery color.
* Using authorized batteries purchased from CenTrak will have assurances that include the device production date, shipping
and storage conditions, and direct shipment from the manufacturer. Batteries purchased from commercially available sites
such as Amazon, Batteries Plus, BattDepot, etc. (even if these are of the same brand, make and model number as CenTrak) are
not acceptable replacements. Batteries from a single manufacturer can vary greatly in performance and may not meet CenTrak
standards for manufacturing, storage and handling.

Effects of Using Unauthorized Batteries
The following may also be experienced if unauthorized batteries are used:
•Inconsistent device performance. CenTrak does not warrant performance of any kind for
batteries not purchased from CenTrak or a CenTrak Authorized Reseller.
•Inaccurate Low Battery Indications (LBI). CenTrak Pulse™ will not provide accurate Low
Battery Indication (LBI) data. This feature is designed to function using only CenTrak authorized
batteries, based on thousands of hours of field testing.
•Increased Labor Cost. Based on time spent changing batteries and finding equipment in order to
change batteries more frequently.
Using Connect Pulse™ to Determine When to Replace Batteries
Pulse is a cloud-based software that aggregates and analyzes data from CenTrak devices and presents
the current health of the overall network and hardware, including tags, sensors, monitors, exciters,
and stars, and recommends maintenance activities to ensure customer network uptime, reliability,
and strong health.
Pulse will display the battery status of battery-powered devices in 3 main categories:
•Good. When the battery health of a CenTrak device is strong, it will appear with a "Good" status.
No action is needed for a device in this status.
•Less than 90-Days. When a CenTrak device's battery has depleted to a state where CenTrak has
estimated life expectancy is less than 90-days, it will appear in the "Less than 90-Days status".
CenTrak recommends using this status for battery change activity planning and forecasting,
including acquiring supply of authorized batteries, scheduling staffing resources, and notifying
affected departments of the battery change schedule and any impact it may have. CenTrak does
not recommend replacing batteries in devices while in this status as Pulse will not automatically
reset the device to the "Good" bin. Should the customer choose to change batteries while in this
status, they must contact CenTrak Support with Device IDs and date when the battery was
changed, so that a manual replacement indication can be made by CenTrak Support. Note: Not
all CenTrak devices support the Less than 90-Days status.
•Less than 30-Days.When a CenTrak device's battery has depleted to a state where CenTrak has
estimated life expectancy to be less than 30-days, it will appear in the "Less than 30-Days" status.
CenTrak recommends replacing batteries while in this status as soon as possible to avoid battery
failure. When a device is in the Less than 30-Days status and the battery is replaced with an
authorized battery, Pulse will automatically process battery replacement indications and move
the device to the "Good" bin.

Note: Devices with visible battery contact issues (bent, water or humidity corrosion, battery corrosion,
etc.) will result in degraded performance and may experience premature entry into the "Less than 90-
Days" or "Less than 30-Days" status in Pulse, even if an authorized battery is used.
Connect Pulse™ Automatic Battery Replacement Indication
When a device is in the "Less than 30-Days" status and the battery is replaced with a new, authorized
battery, Pulse will aggregate battery health data over time and automatically process battery
replacement indications and move the device to the "Good" bin. The following is the most common
battery replacement workflow. The workflow assumes the device remains online and in good network
coverage for at least 10 days during processing.
•After a new, authorized battery has been added, within 48 hours the device should move to the
"Good" status with a blue battery icon. The blue battery icon denotes an initial indication of a
new battery and further processing will occur to complete the battery replacement routine. Note
that infrastructure devices (i.e. monitors, exciters, stars) currently does not utilize the blue
battery icon state.
•Additional processing will occur over the next week. When Pulse has made a final determination
that a new, authorized battery was added, processing will complete, resulting in the icon
changing to green and the "Battery Replaced On" field will update to the date when Pulse first
detected the new battery. This process generally takes up to 5 days after a new battery was
added but can take up to 10 days depending on the health of the battery or if the device is
removed from network coverage for a short period of time.
•If during the additional processing, the criteria for a new, authorized battery was not met, the
device will move back to the "Less than 30-Days" status to denote to users that there was an
issue with the battery and a new battery should be added.
If a device is not in consistent network coverage during processing, the device may:
•Remain in the "Less than 30-Days" status until it regains proper network coverage
•Receive the initial battery replacement indication by moving into the "Good" status with a blue
battery icon, but then move back to the "Less than 30-Days" status around the 11th day after
adding the new battery.
Note: Devices with visible battery contact issues (bent, water or humidity corrosion, battery corrosion,
etc.) will result in degraded performance and may not properly update in Pulse even if an authorized
battery is used.

Common Battery Replacement Failure Reasons and when to RMA
Devices
The following are common battery replacement failures:
•An unauthorized battery was used and Pulse did not detect battery health levels that match
the standard, new, authorized battery health levels. The device would remain in the "Less
than 30-Days" status.
•An unauthorized battery was used and Pulse did initially detect battery health levels that
match the standard, new, authorized battery health levels, but then the battery health
levels immediately dropped below the standard, new, authorized battery health levels.The
device may have initially moved to the "Good" status (with a Blue battery icon) but would be
moved back to the "Less than 30-Days" status around the 11th day after the battery was changed.
•An authorized battery was used and Pulse did initially detect battery health levels that
match the standard, new, authorized battery health levels, but then the battery health
levels immediately dropped below the standard, new, authorized battery health levels due
to battery contact issues.The device may have initially moved to the "Good" status (with a Blue
battery icon) but would be moved back to the "Less than 30-Days status" around the 11th day
after the battery was changed.
•Device was online initially and an authorized battery was used and Pulse did initially detect
battery health levels that match the standard, new, authorized battery health levels, but
then the device went offline before Pulse could finish processing to complete the battery
replacement indication. The device may have initially moved to the "Good" status (with a Blue
battery icon) but would be moved back to the "Less than 30-Days" status around the 11th day
after the battery was changed.
•Device was offline leading up to battery replacement and continues to be offline after
battery replacement, therefore Pulse did not receive or register any battery health
information. The device would remain in the "Less than 30-Days" status.
If a battery replacement failed for a particular device, CenTrak recommends replacing the batteries
one more time with authorized batteries. If a failure occurs again, CenTrak recommends replacing the
device with a functioning device and sending the failed device back to CenTrak under RMA for further
analysis. Contact a CenTrak representative for RMA instructions.

How Battery Health is Calculated
Due to lithium batteries generally maintaining a steady battery output until the very end of its life and
the added complexity of different chemical variations of lithium batteries, battery health algorithms
utilize multiple proprietary technologies and methods that are assessed over periods of time to
determine time left before a device becomes inoperable. Methods include historical usage, time-in-
motion, communication rates, current voltage, the ability to recover after applying a load on the
battery and additional proprietary methods. Measuring voltage alone is not a sufficient indication of
battery health and time remaining.
By focusing on estimating time left on batteries it can provide tangible and actionable information to
give customers a better opportunity to plan battery replacement schedules and activities.
Battery Life Expectations
Battery life is heavily dependent upon activity level, use case, update speeds, time spent in Wi-Fi vs.
Active UHF, and utilization of LF, among other factors. Additionally, actual battery life may vary due to
operating temperature, product software/hardware versions, battery manufacturing irregularity and
other environmental factors.
In the event that CenTrak’s select battery manufacturers deliver defective batteries which significantly
underperform expectations, CenTrak may elect to ship the replacement batteries at no charge,
assuming the client is current with their Systems Maintenance Agreement.
