AUTOPHIX BAS100 12V/24V Battery Tester — 100–2000 CCA Load Tester, AI Smart Chip & LCD

The AUTOPHIX BAS100 is a handheld 12V/24V battery and charging-system tester that evaluates SOH, SOC, cranking ability, and alternator performance for 100–2000 CCA batteries.

If you maintain vehicles, equipment, or a fleet, quick and reliable battery diagnostics prevent unexpected failures and unnecessary replacements. The AUTOPHIX BAS100 combines a compact design, high-conductivity clamps, and an AI smart chip to deliver fast, accurate readings across common battery types and industry standards. It’s suitable for cars, trucks, motorcycles, RVs, boats, lawn equipment, and many commercial and agricultural machines.

How does the BAS100 determine battery health?

The tester measures State of Health (SOH) and State of Charge (SOC) using a controlled load and internal algorithms to estimate remaining capacity and battery aging. It also runs a cranking test to verify starting performance and a charging test to check the alternator or charging system.

• SOH and SOC percentages reported on an easy-to-read LCD.
• Cranking test simulates real-start conditions to confirm starting power.
• Charging system check reveals alternator or regulator issues.
• Requires correct input of battery type, CCA/AH, and temperature for best accuracy.

Which batteries and vehicles will it work with?

The BAS100 supports both 12V and 24V lead-acid batteries rated from 100 to 2000 CCA and recognizes flooded, AGM (flat and spiral), GEL, and EFB chemistries. It accepts many international rating standards so you can use it on a wide range of vehicles and equipment.

• Compatible with CCA, BCI, CA, MCA, JIS, DIN, and SAE ratings.
• Ideal for cars, SUVs, pickups, vans, light trucks, and heavy equipment.
• Also suitable for motorcycles, boats, jet skis, lawn mowers, ATVs, and tractors.
• Not for 6V/8V or lithium (Li-ion) batteries.

What safety and accuracy features does it include?

Designed with an industrial ABS housing and a 4-in-1 protection system, the tester minimizes risk from misuse or harsh environments. High-conductivity copper clamps and an AI-driven chip deliver stable readings with industry-level precision.

• Reverse-polarity, short-circuit, over-voltage, and over-current protections built in.
• Temperature compensation for accurate readings in extreme heat or cold.
• Strong-spring copper clamps with anti-slip coating for reliable contact.
• AI smart chip gives fast, consistent results with 99.98% diagnostic accuracy when parameters are correctly set.

How easy is it to use the BAS100 during routine checks?

Operation is straightforward: clip the positives and negatives and the unit begins testing whether the battery is installed or removed, even if the battery is fully discharged. The LCD displays results clearly so both professionals and DIYers can interpret findings quickly.

• Plug-and-play testing—no complex setup required.
• Portable, compact handheld form for workshop or field use.
• Works on installed or removed batteries; can test dead batteries too.
• Simple menu to select battery type, standard, and CCA/AH before testing.

Who is this for? The AUTOPHIX BAS100 is built for mechanics, fleet managers, technicians, and vehicle owners who need dependable, repeatable battery and alternator diagnostics. It’s also useful for DIY enthusiasts and professionals who troubleshoot starting and charging problems across a variety of vehicles and equipment. Note: always select the correct battery type, rating, and temperature setting before testing and do not use the BAS100 on 6V/8V or lithium batteries.
