BATTERY INFORMATION
WARNING -
Use only the charger supplied by Mesa Laboratories. Use of any other charger will
void the warranty, could cause damage the instrument, or cause personal injury.
CAUTION:
Do not open or dismantle the 90XL meter as there are no user serviceable parts
inside. Return the Display Module to Mesa Labs or authorized distributor for service.
CAUTION:
Do not charge the 90XL when ambient temperature is greater than 45°C. (113 °F)
CAUTION:
If the battery fully discharges, the date and time functions must be reset.
The lithium-ion rechargeable battery in the 90XL meter is designed to provide years of reliable
service. After 500 complete charge/discharge cycles, it will retain approximately 80% of its
original capacity. The amount of time that a fully charged battery will operate the 90XL meter
depends greatly on how brightly the display’s backlight is illuminated. At full brightness, the
running time will be less than half the running time when the backlight is turned off.
Sensor modules use significantly less power than the display module and won’t affect the
amount of operating time as much as the backlight.
