Product Information

About this item

• ①This is an intelligent instrument that integrates the four functions of battery testing(analyzing), charging, discharging and maintenance. It is designed with a portable plastic shell, and with color TFT displayer and silicon touch keys.For 2V~18V 2-200Ah Pb-Acid(AGM,Calcium,GEL, MF,EFB,SLA, VRLA, WET, Gel), Li-Ion, LiFePO4, NiMH, NiCd Batteries，It can be used to perform performance testing, capacity testing, characteristic curve measurement, and activation and maintenance of long-term storage batteries for various commonly used rechargeable batteries.widely used for performance testing and routine maintenance of most rechargeable batteries in many portable electronics electrical devices.
• ②Battery Charging: can set constant current & constant voltage for charging process.According to the selected battery type and charging parameters, the system automatically calls the best charging process curve. When charging, the LCD displays the following information：Discharging,SOC,SOH,RES,Time run,Discharg，battery voltage, battery current,battery capacity, battery type，Full charged from empty,test Capacity,Full charged from no-empt,est. Capacity,charging curve of the battery.It has a variety of abnormal safety protection measures such as battery reverse connection, wrong connection, short circuit, overvoltage, undervoltage, over-current and over-current heat.
• ③Battery Discharge: can set constant current value & cut-off voltage for discharging.Automatically discharge according to the selected parameters;During discharging process, screen will be following view：Discharging,SOC,SOH,RES,Time run,Discharg，Voltage, battery capacity, battery type,Discharged from full,test Capacity,Discharged from non-full,est. Capacity,charging curve of the battery.
• ④Battery Test&Analyzer: can measure battery voltage, internal resistance, SOC, SOH, true effective capacity Ah value and charge/discharge curves.Measure battery voltage, internal-resistance, SOC and SOH within 5 seconds SOC, means State-of-charge of battery, range is 0 ~ 100%.SOH, means State-of-health of battery, range0~100%.
• ⑤Battery Maintenance:Automatic maintenance based on selected battery parameters:For batteries that have been idle for more than 6 months or have been floating charged for a long time, it should be regularly (preferably every 6 months or so) standard charging and discharging maintenance process. The standard maintenance procedure is to use 0.2C current first fully charge the battery - then drain the battery with 0.1C current - then use 0.1C charge current to full fill the battery. After finished this maintenance process, the vitality, the life time and the effective capacity of battery will be protected and improved to the maximum.
• ⑥Engine Diagnostics:This product accurately monitors the starting current during engine startup and the generator voltage after startup. By analyzing these two key data points, it can quickly pinpoint common issues such as "vehicle fails to start," "slow or weak cranking," "frequent battery drain," and "battery warning light on the dashboard," clearly identifying whether the problem lies with the battery, generator, or starter motor, providing reliable evidence for fault diagnosis.
