Preface
The frequently used rechargeable batteries fall into these types: Li-ion battery, Nickel-Cadmium
battery, Nickel-Metal hydride battery, sealed lead-acid battery, and so on.
Among them, the Li-ion battery features large capacity, light weight, high rechargability, so it is
widely used in fields such as mobile phone, PDA, digital camera, camcorder, and notebook
computer. It is the most advanced rechargeable battery. Here Li-ion battery refers to the finished
Li-ion battery pack, which consists of lithium battery core (Li-ion core or lithium polymer core)
and lithium battery protection panel.
Nickel-Cadmium battery has a longer history. It features low cost, low impedance, and
high-current discharge, so it is still widely used in electric tools and electric vehicles.
Nickel-Metal hydride battery is similar to Nickel-Cadmium battery, but it is more
environment-friendly because it contains no heavy metal. It is widely used in common customer
electronic products and has almost become a substitute for the Nickel-Cadmium battery.
Small sealed lead-acid battery is also known as maintenance-free lead-acid battery. Because of
mature technique, it is widely used for fixed standby power supply, such as UPS and emergency
lighting.
To check the status of these rechargeable batteries, we have launched a specialized integrated
battery tester. This tester can measure basic parameters of the rechargeable batteries accurately,
including open-circuit voltage, impedance, charge/discharge performance, and capacity. For
lithium battery, it also offers functions such as over-charge protection, over-discharge protection,
over-current protection, and short-circuit protection, and can measure the corresponding values.
This greatly facilitates the production and pre-sale/after-sale services of batteries. With this tester,
you can easily and visually identify the performance and conditions of the batteries. You can also
use the fast-screening function, namely, you can set upper and lower thresholds to quickly detect
the defective batteries among a batch of finished batteries, improving the production efficiency.
Besides, the tester offers some unique auxiliary functions, so that it has some features of a
common communication tool, thus improving the flexibility and enlarging the application scope of
the tester.
In addition, the software of this tester can be upgraded as required. The base version of the tester
can be upgraded to connect with a computer. After that, the computer can be used to set and save
test data, automatically keep the test records. The test data of each battery can be kept according to
its bar code, facilitating the analysis of and control over the production quality and problem
