Cyclic life test
Cyclic life of batteries indicates their life time and is defined by many standards.
Each standard has its own definition for obtaining the cyclic life, depending on the
battery technology and operating mode. In
Battery and Energy Generators Research Lab,
the cyclic lif of the cells can be obtained using different devices:
Characteristics

Neware 5V-12Amps battery tester and cycler is designed to
analyse battery cells up to 5V which is quite suitable for almost any cell including lead-acid, NiCad,
NiMH, Li-ion and any other technology. The device can also be used for testing the capasitors, supercaps,
solar cells (with voltage less than 5V) and more. The battery packs with voltage less than 5V, the cycler
can be used without any consideration. The device contains 16 distinct channel each of wich can test
from 1mA to 12A. For increasing the accuracy, 3 different voltage levels are controlled internally, so that
the controllers become quite accurate. For higher required currents, the channels can be used in parallel
(up to 4 channels) and deliver 48A which is quite enough for many systems. The device can be used for
obtaining the cyclic life of the cells, up to 65536 cycles. All the fucntions are automatically taken care of
and the resutls are stored in local files for further usage.

Neware 30V-60Amps battery tester and cycler
is and automated accurate cycler which can perform cyclic tests with whatever program that you want.
The test can be carried on the battery packs up to 30V and 60A in two different channels. For higher
applied current, the channels can be internally connected in parallel so the total
current reaches 120A which is quite enough for almost any battery. The cycle can be setup with as many
steps as necessary and repeated up to 65000 times.
