12V Battery Tester Features

1.Fast and smooth running speed with STM-32 chip set hardware

2.Accurate test results, using high precision amplifier and calibrated by professional battery testing tool, BST100 reading accuracy up to 99%.

3.Wide testing range cover from CCA 100- 2000 , 3- 220 AH, best in the market.

4.Industry initiative graphical battery voltage real time monitoring, can be analysis battery data more accurate.

5.Unique battery results display in percentage and meter mode.

6.Test all automotive cranking lead acid battery, including ordinary lead acid battery, AGM flat plate battery, AGM spiral battery, and Gel battery, etc.

7.Polarity reverse connection protection, reverse connection will not damage the tester or affect the vehicle and battery.

8.Directly test the battery with loss of electricity, no need to full charge before testing.

9.Testing standards include currently the world's majority of battery standards, CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, GB. 10.BST100 is used to test a wide range of 12V batteries (Starting [SLI], Deep Cycled and Marine) of Wet (Flooded), VRLA or Maintenance Free (MF), Sealed Maintenance Free (SMF), Absorption Glass Mat (AGM) and GEL EPB cell

Disadvantages of the load test method:

(1) Only available for large capacitance battery or storage battery. The small capacitance battery can not load 40-80A large current in 2-3 seconds.

(2) When the large current going through the battery, there comes out a polarization phenomenon from the internal electrode, which can cause polarization internal resistance. As a result, it has to be tested in a short time. Otherwise, there will be a large error in the internal resistance value.

(3) The internal electrode will be damage generally when the large current goes through the battery.
