Preface
The freq ently sed rechargeable batteries fall into these types: Li-ion battery, Nickel-Cadmi m
battery, Nickel-Metal hydride battery, sealed lead-acid battery, and so on.
Among them, the Li-ion battery feat res large capacity, light weight, high rechargability, so it is
widely sed in fields s ch as mobile phone, PDA, digital camera, camcorder, and notebook
comp ter. It is the most advanced rechargeable battery. Here Li-ion battery refers to the finished
Li-ion battery pack, which consists of lithi m battery core (Li-ion core or lithi m polymer core)
and lithi m battery protection panel.
Nickel-Cadmi m battery has a longer history. It feat res low cost, low impedance, and
high-c rrent discharge, so it is still widely sed in electric tools and electric vehicles.
Nickel-Metal hydride battery is similar to Nickel-Cadmi m battery, b t it is more
environment-friendly beca se it contains no heavy metal. It is widely sed in common c stomer
electronic prod cts and has almost become a s bstit te for the Nickel-Cadmi m battery.
Small sealed lead-acid battery is also known as maintenance-free lead-acid battery. Beca se of
mat re techniq e, it is widely sed for fixed standby power s pply, s ch as UPS and emergency
lighting.
To check the stat s of these rechargeable batteries, we have la nched a specialized integrated
battery tester. This tester can meas re basic parameters of the rechargeable batteries acc rately,
incl ding open-circ it voltage, impedance, charge/discharge performance, and capacity. For
lithi m battery, it also offers f nctions s ch as over-charge protection, over-discharge protection,
over-c rrent protection, and short-circ it protection, and can meas re the corresponding val es.
This greatly facilitates the prod ction and pre-sale/after-sale services of batteries. With this tester,
yo can easily and vis ally identify the performance and conditions of the batteries. Yo can also
se the fast-screening f nction, namely, yo can set pper and lower thresholds to q ickly detect
the defective batteries among a batch of finished batteries, improving the prod ction efficiency.
Besides, the tester offers some niq e a xiliary f nctions, so that it has some feat res of a
common comm nication tool, th s improving the flexibility and enlarging the application scope of
the tester.
In addition, the software of this tester can be pgraded as req ired. The base version of the tester
can be pgraded to connect with a comp ter. After that, the comp ter can be sed to set and save
test data, a tomatically 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 prod ction q ality and problem
