CHOOsInG & usInG BATTERIEs FOR yOuR kEsTREl (COnT.)
We strongly recommend you use lithium or LSD NiMH
batteries at all times to avoid battery corrosion damage.
All alkaline batteries are prone to leaking, particularly as
they near full discharge. The potassium hydroxide that
leaks from an alkaline battery causes oxidation damage
to the circuit and components which is often irreversible
and is NOT covered under the Kestrel warranty.
IF YOU CHOOSE TO USE ALKALINE BATTERIES due to
cost or availability, you MUST:
• Remove the batteries for long-term storage (more
than one month of non-use). If you have your Kestrel
set to log data while off, it will slowly drain the
batteries, increasing the likelihood of leaking.
• Set your system battery selection to "Alkaline" to
obtain accurate capacity readings:
» Press
to enter the setup menu.
»
to "System",
»
to select the correct battery type.
»
to exit system setup.
• Change your batteries when below 20% capacity to
avoid fully discharging your batteries.
• Whatever batteries you choose:
• Use national name-brand batteries wherever
possible. Do not mix brands or chemistries of
batteries.
• Do not mix batteries of different ages or usage –
replace both batteries at the same time with new
batteries that have not reached their expiration date.

• Inspect your batteries occasionally (at least every
three months) and remove immediately if you notice
ANY moisture or white crystalline material at either
end.
• Always store your Kestrel meter within the specified
temperature limits: -22.0 °F to 140.0 °F | -30.0 °C to
60.0 °C. Be particularly careful not to leave a Kestrel
meter with batteries installed inside a hot vehicle in
the summer.
What to Do if you Have a leak
If you notice you have a leaking battery, be careful not
to touch it with your bare skin or allow it to come in
contact with your eyes as the leaking material is caustic
and/or toxic. Remove and dispose of both batteries. If
possible, loosen and vacuum out any white powder. DO
NOT BLOW INTO THE COMPARTMENT TO REMOVE THE
POWDER – it can cause eye or skin damage and will be
driven further inside the unit. You may attempt to use a
cotton swab moistened with white vinegar to clean the
contacts and gently swab out the battery compartment.
Do not exert any force against the contacts inside the
battery compartment or you may bend or break them.
Allow the battery compartment to dry completely and
try installing fresh batteries. If your unit powers up you
may continue to use it. If not, you may contract Kestrel
Support to inquire about our Customer Loyalty Trade-In
Program which provides a generous discount towards a
replacement Kestrel meter.
