Analyze Your Battery Step by Step with FOXWELL BT705 Battery Cranking Charging System Tester
- Evaluate Battery Health:
Determine battery status, such as good, bad, or needs charging, and measure cold cranking and aging indicators to replace the battery beforehand.
- Battery Charging System Tester/Alternator Tester:
Evaluate the alternator's health and avoid damaging the battery with overcharge or incomplete charging. It indirectly assesses the alternator’s technical viability by analyzing the fluctuations in battery voltage. Tips: BT705 battery load tester cannot test the alternator directly.
- Clip-on Cold Cranking Tester:
Check the generator's output voltage, detect whether the generator/rectifier diode can bear sufficient power, and if the battery can hold the power.
- Ripple voltage/ Battery Voltage/ Starter Voltage/ Alternater Voltage/ Output Test
Extra Features:
- Quick and accurate test result with upgraded terminal copper clamp, all-round mechanical connection, advanced conductance technology.
- Test diverse battery types: Regular Flooded, AGM Flat Plate, AGM Spiral, GEL, and EFB, rated from 100CCA to 2000CCA and diagnose multi-rating systems such as CCA, CA, MCA, JIS, DIN, IEC, EN, SAE.
- Battery Life Test: Check the battery's healthy staus such as SOH(State of Health), SOC(State of Charge), CCA value, CCA rating, voltage, internal resistance etc.
- In vehicle & Out of vehicle test setting: Determining parasitic draw when the vehicle cannot crank.
- Polarity reverses connection protection: Does not emit light, heat or spark ,or discharge battery-keeps operation safe for all levels of users. Automatic temperature compensation.

Battery Life in your HandsShow the battery life status in 3 seconds, easily know how to solve the battery issues.
The battery tester keeps the results of last test only. When you start a new test, the last results are overwritten. |
Talk To Your Battery DeeplyThe BT705 tests charging system to check if the output is in normal status and show you the problems.
|
Refuse to Replace Battery All the TimeRefuse to replace battery blindly when the vehicle cannot crank. Make sure it's really broken.
Note: Before starting the test, inspect the alternator drive belt. A belt that is glazed or worn, or lacks the proper tension, will prevent the engine from achieving the rpm levels needed for the test. |
