Whites MATRIX 100, Instruction Manual

11

Batteries

One 9V battery is included with the detector. Use a  9V alkaline, 9V lithium-

manganese dioxide, or externally charged 9V battery. If the battery is fresh or 

recently recharged (more than 7V), the LED next to the “ON/OFF” button will 

produce a green light. If the battery is discharged (less than 7V) the LED will 

flash a yellow light.  It is recommended that you replace the battery if the 

light is yellow.

Battery life

Based upon measurements, battery life for a 600 mA-hour alkaline battery at  

room temperature:

On   216 hours  9 days

Off  2880 hours 120 days

Battery life is doubled with the 1200 mA-hour lithium-manganese dioxide

batteries

.

Rechargeable 9V batteries can be used, but battery life per charging is  

typically much shorter than the life of 9V alkaline batteries, and depends    

upon battery type and the battery recharging system.

Do 

NOT

 use the earbud jack as a recharging port! Use of the earbud jack as  

a recharging port may damage the Matrix 100 or the battery charger, and will  

void the warranty.

Battery temperature ratings

Alkaline batteries are rated by the manufacturer:

Energizer  -18°C to 55°C (0°F to 130°F)

Panasonic  -20°C to 54°C (-4°F to 130°F)

Lithium-manganese dioxide batteries are rated by the manufacturer:

Duracell  -20°C to 60°C (-4°F to 140°F)

Energizer  -40°C to 60°C (-40°F to 140°F)

Ultralife  -20°C to 60°C (-4°F to 140°F)

Manufacturer’s ratings are based upon operating loads quite different from  

the Matrix 100 so you may see different results.
