About products and suppliers:
Alibaba.com is a veritable source for those looking for laptop battery testers. These are multi-channel battery analyzers for various types of batteries. Buyers use these portable laptop battery testers for applications involving electrode material research, capability grading, battery performance tests, battery pack testing, small-scale battery formation, etc. Battery analyzers are computer driven. Professional battery testers require a laptop to control them. Manufacturers use the latest version of controller software and calibrate them.

Typical laptop battery testers have 8 channels for testing small coin cells to cylindrical batteries ranging from 0.1 mA to 20 A, with voltages ranging from 5 to 20 V. Each channel of the analyzer has independent constant-voltage and constant-current circuits. The control software in the laptop controls each channel independently in these portable laptop battery testers. One laptop can simultaneously control up to 20 such analyzers. Each battery tester machine works on a main power of 220 VAC, and typically uses a 16-bit ADC and a 14-bit DAC for accurate readings.

Buyers looking for laptop battery testers must review the specifications offered by the manufacturers before buying them. Of special importance is the current and voltage ranges offered, and the resolution of the measurement. Other parameters that could be important are the total power dissipation, stability of readings, current response time and step time rate of the portable laptop battery testers. Buyers must make sure the system offers both constant voltage and constant current for charging as well as discharging batteries.
