A voltage reading alone doesn’t tell you whether a battery can actually deliver current under real load — a battery can show a healthy resting voltage and still fail the moment it’s asked to crank an engine. A proper load tester closes that gap.
What It Is
This is the ANCEL BA101 Plus, a 6V/12V car battery tester with a 20-2000 CCA load testing range, designed to evaluate battery health, cranking capacity, and charging system condition beyond what a simple voltmeter reading can show.
Key Features
- 6V and 12V battery compatibility
- 20-2000 CCA (cold cranking amps) load testing range
- Evaluates battery health and charging system condition, not just resting voltage
- Digital display for clear, direct results
Pros and Cons
At 4.3 stars, reviewers consistently note the value of getting an actual load-tested result rather than just a voltage number — a meaningfully more accurate way to catch a battery that’s about to fail under real-world starting conditions.
At $69.99, it costs more than a basic multimeter-style battery check, though for shops or techs testing batteries regularly, the accuracy improvement over voltage-only testing generally justifies the cost.
Who It’s For
Maintenance techs, mechanics, and fleet operators who need accurate, load-tested battery diagnostics rather than a simple voltage check.
Verdict
A genuine step up in battery diagnostic accuracy over voltage-only testing, worth it for anyone testing batteries with any regularity.
