9 K-METRON BATTERY POWER

9.1 Battery Type

K-METRON is designed for use with a single Lithium PP3 9-volt battery. Using a non-lithium
variant of a PP3 9-volt battery, such as an alkaline battery, will significantly reduce battery
life. An equivalent rechargeable battery may also be used but this will require regaular
removal of the battery to charge it separately.

9.2 Replacing the Battery in K-METRON

To replace the battery, remove the cover screw. Carefully unclip the spent battery from the
battery cover lid and unclip the battery terminals from the flying power lead. Attach the
terminals on the new battery and ensure they clip on securely. Insert the charged battery
into the clip and remount the cover. Make sure the battery cable is not trapped by the
cover.

9.3 Battery Life

It is recommended that a PP3 lithium battery is used to provide the longest battery life.
When used continually without transmitting data the battery life is in the region of 50 hours
based on transmission of data at a rate of 10 transmissions/hour the estimated battery life
would be in the region of 40 hours. NB. If a Lithium battery is not used the battery life may
be significantly compromised.
