Foreign users teach you to test whether the battery has electricity

Newly bought dry batteries, put on for too long, do not know if there is no electricity? Many people will encounter this situation, but not everyone has the instrument for measurement. Recently, foreign user kipkay has uploaded a video on Youtube to teach people how to use simple methods to test.

According to the video display, the user only needs to hold the positive electrode up in the hand and gently drop it to the ground. If the battery can stand normally, then there is still electricity; if it can't stand, the electricity is basically consumed.

Kipkay indicates that the above tests are limited to commonly used alkaline dry batteries.

Heat Meters are one kind of meters measuring the heat consumption. In order to save the energy and decrease the environment pollution, the heat meters are more and more popular for the modern buildings. Heat meters can realize centralized heating supply. Now with the rapid technology development, the heat meters also experience a fast way of growing up. Now the government of the world starts to pay much attention to the building remolding and new buildings heat meter installation. As the new type of energy calculation, the heat meters have the advantages of higher accuracy, energy saving and easy installation.

From the functions of the different types of heat meters, there are mechanical heat meters, Digital Heat Meter,Ultrasonic Heat Meters, M-bus Heat Meters and also wireless heat meters. Our company, Berggruen Technology Co.,Ltd never stops the steps for further higher technology research and development. We are devoted to study the new technology in the world to make better quality heat meters.
