4. Battery replacement

The iNode Beacon CR2032 battery should last up to 6 months. In the case of a 14250
battery that has five times the capacity, it will be correspondingly longer. In fact, the speed of its
consumption depends on many factors, e.g. operating temperature, frequency of cooperation with a
PC or smartphone (reading of recorded data), set transmission power level, etc. The battery voltage
characteristics as a function of time (energy consumed from it) is for a long time. practically flat.
Only at the end of the battery voltage begins to decrease rapidly, and its internal resistance
increases, which leads to rapid wear.
To replace the CR2032 battery:
Open the housing:

The iNode case can be opened without using tools. It is most convenient to do it just like a
nut shell opens. That is, insert your thumb nails into the gap between the two parts of the
housing and open it. Inside is a printed circuit board, most of which is occupied by a metal
battery holder.
Remove the circuit board from the housing. The battery is inserted into the side grip. It

cannot be removed if the board is in the housing.
Slide the old battery out of the holder.

Insert a new battery:

The battery, like a coin, has two sides. One of them has a large "+" sign and usually the
name of the company. The other side usually has no markings. The battery should be
inserted so that the side marked with "+" touches the metal handle (the "+" sign also has it).
If the operation was carried out correctly, the LED should start flashing.
Insert the plate into the housing:

The circuit board is not perfectly round. It has a slight chamfer on one side. It corresponds
to a small bulge inside the housing. When inserting the plate into the housing, make sure
that these two elements are opposite each other.
Close the housing:

On one of the housing parts there is a pin that prevents the battery from sliding out of the
holder. It must be set so that it is close to the bevel described in the previous point. Only
with this setting can the housing be closed.
To replace the 14250 battery:
1. Open the housing;
2. Slide the old battery out of the holder.
3. Insert a new battery paying attention to the polarity (minus in the direction of contact with
the spring or as described).
4. Close the housing:
