MEET WONTPRIX

What kind of batteries can the WontPrix test?
WontPrix tests a wide range of 12V batteries (Starting/SLI, Deep Cycled, and Marine), including Wet (Flooded), VRLA or Maintenance Free (MF), Sealed Maintenance Free (SMF), Absorption Glass Mat (AGM), EFB, and GEL cells.

Can it test my starter and alternator charging systems?
Yes! Beyond standard battery tests, WontPrix features specialized cranking and charging system tests to verify if your starter motor has sufficient power and if your alternator is outputting the correct voltage.

How accurate are the test results?
WontPrix uses highly advanced internal resistance and voltage calculation technology to provide precise measurements, calculating the exact cold cranking capability of the battery and its aging extent.

Does it support international standard measurements?
Absolutely. WontPrix supports almost all major battery standards globally, including CCA (100-2000), BCI (100-2000), CA (100-2000), MCA (100-2000), JIS (26A17-24SH52), DIN (100-1400), IEC (100-1400), EN (100-2000), and SAE (100-2000).

What languages are available on the device?
The tester comes with built-in multi-language software that supports 8 languages: English, German, French, Dutch, Russian, Spanish, Italian, and Portuguese.

Do I need a battery or external power source to run the tester?
No. WontPrix is powered directly by the 12V vehicle battery you are testing. Simply connect the red clamp to positive (+) and black to negative (-) to power on and run tests immediately.
