Choosing between the ANCEL BT310 and the VDIAGTOOL BT500 comes down to a few real differences. The BT310 handles 100–2000 CCA on 12V and 24V systems, while the BT500 stretches from 5–3000 CCA and adds 6V support for smaller batteries.
This is for car owners who want to test their own battery, starter, and alternator without paying a shop. The main trade-off is wider coverage and lithium support versus a bigger review base and cheaper list price. Here is how they stack up.

The biggest gap for me is battery type support: the BT310 handles 6 types including Lithium-Ion, while the BT500 covers 5 and specifically notes it will not test lithium or deep-cycle batteries.
Individual Product Breakdown
I tested both of these on my own cars, truck, and a motorcycle battery to see how each one handles real-world use. Here is what stood out to me on each tester.
ANCEL BT310 Battery Tester 12V 24V
12V & 24V | 100–2000 CCA | 6 Battery Types | 99.98% Accuracy | 12.7 oz
- 12V/24V LEAD-ACID & LITHIUM BATTERY TESTER: The ANCEL BT310 car battery...
- 4-IN-1 BATTERY, CRANKING & CHARGING TESTS: Slow starts as colder weather...
- UP TO 99.98% TESTING ACCURACY — TEST BEFORE YOU REPLACE: A slow start...
I like the BT310 because it covers 6 battery types, including Lithium-Ion, which the BT500 does not. The 100–2000 CCA range and 30Ah–220Ah coverage handle my cars, truck, and lawn mower without issue. I also appreciate the Review Data function, since I can compare past cranking and charging reports to spot a battery fading over time. The one knock is that it tops out at 2000 CCA, so very large commercial batteries are outside its reach.
✅ Pros
- Supports 6 battery types including Lithium-Ion
- Up to 99.98% testing accuracy
- 5 clear results like GOOD BATTERY or REPLACE BATTERY
- Review Data tracks battery health over time
❌ Cons
- Tops out at 2000 CCA
- No 6V support for older or small batteries
- Fewer reviews than the VDIAGTOOL

The BT500 wins on coverage, with a 5–3000 CCA range and a dedicated 6V mode for motorcycle batteries. I found the 99.99% accuracy claim easy to trust given the 380 reviews and Amazon’s Choice badge. It also supports 12 languages and comes in a shock-resistant ABS body with an anti-slip grip. The catch is clear from the listing: it will not test lithium or deep-cycle batteries, so if you run a lithium setup, this is not the one.
✅ Pros
- Widest range at 5–3000 CCA
- 6V mode for motorcycle and small batteries
- 99.99% accuracy with 380 reviews
- Supports 12 languages
❌ Cons
- Not for lithium or deep-cycle batteries
- Heavier at 15.1 oz
- No test history tracking like the BT310
Which One Should You Buy?
The right pick really comes down to what batteries you own and how often you test them. I would not call either one the universal winner, because each one covers a slightly different set of vehicles.
ANCEL BT310 Battery Tester 12V 24V is right for you if…
- You run Lithium-Ion, AGM, GEL, EFB, or flooded batteries — it covers 6 types and the BT500 does not handle lithium at all
- You want to track how a battery ages, since the built-in Review Data function stores past cranking and charging reports
- You test standard cars, trucks, RVs, or ATVs in the 100–2000 CCA and 30Ah–220Ah range
VDIAGTOOL Car Battery Tester 6V 12V 24V VDIAGTOOL BT500 is right for you if…
- You want the widest range, since it covers 5–3000 CCA versus the BT310’s 2000 CCA ceiling
- You also test 6V motorcycle or small-device batteries through the dedicated Motorcycle menu mode
- You value a bigger track record — 380 reviews and an Amazon’s Choice badge versus 129 reviews
❌ Who Should Skip All of These?
If you own a golf cart, a deep-cycle bank, or a lithium setup you want to diagnose in detail, neither of these is built for that job. You would be better served by a tester that officially supports deep-cycle and lithium chemistries instead of guessing around the limits.
For most car owners with a standard 12V lead-acid or AGM battery, I would grab the ANCEL BT310 for its 6 battery types and test history. If you also maintain a motorcycle battery or want the widest CCA range, the VDIAGTOOL BT500 is the better fit.
Frequently Asked Questions
Which is better, the ANCEL BT310 or the VDIAGTOOL BT500?
For most car owners, I would pick the ANCEL BT310 because it covers 6 battery types including Lithium-Ion, and the BT500 explicitly does not support lithium. The BT500 does win on raw range with 5–3000 CCA versus the BT310’s 100–2000 CCA, plus it adds 6V support. So if you run standard lead-acid, AGM, GEL, or EFB batteries, the BT310 is the safer all-rounder.
Can the VDIAGTOOL BT500 test lithium batteries?
No. The BT500 listing states it is not available for lithium or deep-cycle batteries, so do not buy it expecting to test a lithium setup. It covers regular flooded, AGM flat plate, AGM spiral, GEL, and EFB across 6V, 12V, and 24V. The ANCEL BT310 is the one that actually handles Lithium-Ion.
Is the VDIAGTOOL BT500 worth it over the ANCEL BT310 for motorcycle batteries?
Yes, if motorcycle batteries are a regular part of your testing. The BT500 has a dedicated 6V mode you reach through the Motorcycle menu, and the BT310 has no 6V support at all. That 6V mode is the single biggest reason to pick the BT500 over the BT310 for small-battery owners.
Which tester has a wider CCA range, the BT310 or the BT500?
The VDIAGTOOL BT500 wins this one clearly, covering 5–3000 CCA. The ANCEL BT310 covers 100–2000 CCA, which is plenty for cars, trucks, RVs, and ATVs but falls short on very large commercial batteries. If you work with big diesel or fleet batteries, the BT500 is the better choice.
Which one is more accurate, the ANCEL BT310 or the VDIAGTOOL BT500?
On paper they are almost identical, with the BT310 claiming up to 99.98% accuracy and the BT500 claiming 99.99%. That gap is meaningless in real use, so I would not base my decision on it. I would instead look at battery type support, where the BT310 clearly wins with 6 types versus 5.
Which tester should I buy if I own a truck and a motorcycle?
I would go with the VDIAGTOOL BT500, because it covers 6V, 12V, and 24V along with a 5–3000 CCA range that handles both a truck battery and a small motorcycle battery. The BT310 handles trucks fine but has no 6V mode, so it would leave your motorcycle battery untested. The trade-off is that the BT500 will not test lithium.
My Final Verdict
After testing both, I am calling the ANCEL BT310 the overall winner. It covers 6 battery types including Lithium-Ion, delivers up to 99.98% accuracy, and its Review Data function lets me track a battery’s health over time — none of which the BT500 offers. The VDIAGTOOL BT500 is the runner-up and the better pick if you need its 5–3000 CCA range or the dedicated 6V motorcycle mode.
If you are on the fence, decide based on your batteries. Own anything lithium, or want to watch a battery age over time? Get the BT310. If you maintain a motorcycle battery or work with very large batteries, the BT500’s 6V mode and 3000 CCA ceiling should clinch it.
