AVT5270 B

The AA and AAA cells (both batteries and typical 'batteries') are currently the most popular way of powering many electronic devices. This results in their very wide market offer - you can buy items produced by well-known global manufacturers and the company 'no name', probably having their headquarters far to the east. In a significant way it determines their quality, there are cases with the cell capacity declared on the dust jacket is in fact several times smaller and we are surprised by, for example, a non-functioning TV remote control. Capacitance measurement is also useful for batteries. Their continuous charging and then slow discharging affect the quality of the elements. It is worth having the opportunity to determine the weaker copies.

The device is especially recommended for assessing the condition of AA and AAA cells

Selected parameters:

• measurement of the capacity of AA and AAA batteries and accumulators
• ATmega8 microcontroller
• cooperation with the AVTMOD09 module (UART / USB translator)
• built-in LCD display
• an executive element attaching a test load - a relay
• 9-12Vdc power supply (from an external power supply)
• alternative power supply from the USB port
• a printed circuit board, a set of elements, a programmed layout and documentation in the set
