Instrumentation / Aitelong / battery tester and maintainance instruments /

As a digital storage and multifunction test equipment which can analysis the battery according to the history data.

  • Enhanced over pressure protecting function.
  • Self recovery the over current protecting function.
  • Use the SOC chip to improve the tester stability.
  • Big capacity Lithium cell and AC 100V-240V power supply
  • Low battery indicates.
  • Automatic testing mode make user to test expediently.

SAT-AR01 Storage battery internal resistance tester cans quick and accurate measurement of battery running status. It can show and
record multi group battery voltage resistance etc.And also precisely judge battery s condition (Good or Bad) and Data analyzing

Full automatically switch the testing range and great capacity data storage

  • Automatically switch the testing range between 0.000m -99.999m .
  • store up to 999 groups battery parameter and 200 groups battery parameter setting.
  • USB flash Drive or RS232 for Data transfer


PC software management

  • Automatically analysis battery bad state.
  • Building the history record base, describe the battery sate curve.
  • Batteries contrastive analysis in the same battery pack.
  • All batteries are administrated by different levels(excellent, good, medium, bad)

Regarding the conclusion about Conductance and Capacity

At present, Lead acid storage battery maintenance is applied for the check of Float voltage of battery at home, it has been found that
Voltage is irrelevance with Capacity of battery, because Voltage is only to show battery s basic parameters.
Internationally, Resistance test is widely applied in daily battery maintenance instead of Voltage check, because Resistance is reflection
to internal parameters of battery with high precision worldwide.
Regarding the conclusion about Conductance and Capacity: when battery conductance is lower than 25% of Initial Value (basic value),
battery can t be the test of Capacity. When battery resistance is higher than 2 times of initial value, battery capacity will be lower 80%
of rated capacity.
