Battery gauge display during operation
If nothing is connected to the USB port during operation the internal battery is used to supply power to the
instrument. The battery symbol in the left top corner of the display shows the remaining capacity of the
internal battery. The combinations have the meanings listed below:
The battery is 100% full.
The battery has approx. 2/3 of its capacity left.
The battery has approx. 1/3 of its capacity left.
The battery is empty, approx 10% is left.
If this symbol starts flashing the battery is totally empty and the meter will switch
off shortly.
Battery aging
The battery technology of the
HDM97
is based on Lithium-Ion-Polymer technology. This technology
has many advantages compared with Nickel-Metal-Hydride technology which are lower weight, smaller size,
longer life, no memory effect and higher efficiency. However, after a couple of years (5 years estimated) the
battery's capacity will start decreasing.
Battery replacement
– ONLY BY MANUFACTURER
Do not try to replace the battery by yourself. The battery is mounted directly onto the main PCB inside the
HDM97
, and the main PCB itself contains the battery protection circuit. If the battery is not handled in
the right way, there is extremely danger of fire and explosion. Therefore, this battery can only be replaced
from IBP personnel who have run through a special training in handling Lithium-Ion batteries.
