The Acclope BT60 PRO is the better pick for 24V systems because it supports 6V, 12V and 24V batteries, while the TOPDON BT100 handles 12V only. The BT60 PRO also reaches 3000 CCA and 2–120Ah across those three voltages, compared with the BT100’s 100–2000 CCA at 12V alone.
- Choose the Acclope BT60 PRO if you need to test 24V truck or marine batteries alongside 12V and 6V ones — it covers 6V/12V/24V with a 100–3000 CCA range.
- Choose the TOPDON BT100 if you only work on 12V lead-acid batteries and want a compact tester rated for 100–2000 CCA with AGM, EFB and GEL support.
I compared these two on three things you can check against the spec sheets: voltage coverage, CCA and Ah range, and battery chemistry support. Everything below is based on the listed specifications, not on hands-on testing.

Individual Product Breakdown
In each mini-review I focused on the specs that actually decide a 24V purchase: voltage coverage, CCA and Ah range, battery chemistry support, and the extras like reporting and display. I kept the trade-offs honest so you know exactly what you’re getting.

The BT100 is a tidy 12V tester that covers 100–2000 CCA across flooded, AGM flat plate/spiral, EFB and GEL batteries. I like that it runs three tests — battery health, cranking and charging — and the three-colour LEDs make a quick health read simple. It’s small and light at 9 oz, so it lives in a glove box without fuss. The catch for this topic is obvious: it’s 12V only, so it can’t test a 24V system at all.
✅ Pros
- Supports 100–2000 CCA across flooded, AGM, EFB and GEL
- Three test modes: battery health, cranking and charging
- Compact 9 oz body fits a glove box
- Copper clamps with reverse-polarity and spark-proof protection
❌ Cons
- 12V only — no 24V or 6V testing
- 2000 CCA ceiling is lower than the BT60 PRO’s 3000

This is the one I’d pick for 24V work: the BT60 PRO tests 6V, 12V and 24V batteries with a 100–3000 CCA range and 2–120Ah coverage. It handles flooded, AGM, EFB and GEL, plus lithium voltage/health checks, and the dedicated 6V motorcycle mode is a nice touch. I also like the QR cloud report — no app, just scan and view results in your browser. The limitation is that LiFePO4 CCA readings aren’t guaranteed, so treat lithium as a health check only.
✅ Pros
- Tests 6V, 12V and 24V batteries — the key 24V win
- Wide 100–3000 CCA and 2–120Ah coverage
- QR cloud report with no app needed
- Dedicated 6V motorcycle mode and 3.2 in HD screen
❌ Cons
- LiFePO4 CCA readings aren’t guaranteed
- Not compatible with 48V systems
- Type-C port is for firmware updates only, not charging
Which One Should You Buy?
The “best” pick really comes down to what you’re testing, since the two testers cover different voltage ranges. I’d match the tester to your vehicles rather than to a single winner.
TOPDON BT100 Car Battery Tester is right for you if…
- You only work on 12V batteries and never touch a 24V system — the BT100 is built for 12V lead-acid testing.
- Your batteries fall within 100–2000 CCA across flooded, AGM, EFB or GEL, so the range covers your fleet.
- You want a compact 9 oz tester that tucks into a glove box or center console for quick roadside checks.
Acclope BT60 PRO Car Battery Tester is right for you if…
- You own or service 24V trucks, marine or RV setups and need a tester that actually supports 24V alongside 6V and 12V.
- Your batteries run up to 3000 CCA, so the BT60 PRO’s wider 100–3000 CCA range matters.
- You want to save or share results via the QR cloud report — handy for shops printing test records.
❌ Who Should Skip All of These?
If you work on 48V systems or need to read and clear fault codes, skip both — the BT60 PRO isn’t compatible with 48V, and neither is an OBD2 code reader. A dedicated 48V-capable tool or a proper scan tool would serve you better.
For the common 24V buyer, I’d go with the Acclope BT60 PRO every time — the 6V/12V/24V coverage and 3000 CCA range are exactly what a 24V system needs. Only pick the TOPDON BT100 if you’re strictly 12V.
Frequently Asked Questions
Which battery tester is better for 24V systems, TOPDON BT100 or Acclope BT60 PRO?
The Acclope BT60 PRO wins for 24V, hands down. The TOPDON BT100 is a 12V-only tester, so it simply can’t test a 24V battery at all. The BT60 PRO covers 6V, 12V and 24V with a 100–3000 CCA range and 2–120Ah coverage. If 24V is on your list, the BT60 PRO is the only one of the two that does the job.
Can the TOPDON BT100 test a 24V truck battery?
No — the BT100 is built for 12V lead-acid batteries only, with a 100–2000 CCA range. Its minimum operating voltage is listed at 12V, so a 24V system is outside its design. For 24V trucks, marine or RV batteries, you need the Acclope BT60 PRO instead.
Is the Acclope BT60 PRO worth choosing over the TOPDON BT100 for a mixed fleet?
Yes, if your fleet includes 24V or 6V batteries. The BT60 PRO handles 6V, 12V and 24V with a 100–3000 CCA range, while the BT100 maxes out at 12V and 2000 CCA. For a mixed fleet, the BT60 PRO’s wider coverage means one tester covers everything. The only reason to pick the BT100 is if every battery you touch is 12V.
Which tester handles higher CCA, the BT100 or the BT60 PRO?
The Acclope BT60 PRO goes higher, rated up to 3000 CCA versus the TOPDON BT100’s 2000 CCA ceiling. That extra headroom matters on big 24V truck and marine batteries. If you regularly test high-capacity batteries, the BT60 PRO’s 100–3000 CCA range is the safer fit.
Does the Acclope BT60 PRO test lithium batteries as well as the TOPDON BT100?
The BT60 PRO supports lithium voltage and health checks, but LiFePO4 CCA readings aren’t guaranteed. The TOPDON BT100 focuses on lead-acid types — flooded, AGM flat plate/spiral, EFB and GEL. So for lithium, the BT60 PRO gives you a status check, but neither tester promises precise CCA on LiFePO4.
Which one is easier to use for quick roadside checks?
The TOPDON BT100 is smaller at 9 oz and 5.3 x 3 x 1 inches, so it slips into a glove box easily. The BT60 PRO has a 3.2-inch HD screen and a QR cloud report for saving or sharing results, which suits shops more than quick roadside use. For pure portability I’d grab the BT100 — but only on 12V systems.
My Final Verdict
I’m picking the Acclope BT60 PRO as the overall winner for 24V systems. It’s the only one of the two that actually tests 6V, 12V and 24V, and its 100–3000 CCA range plus 2–120Ah coverage gives you far more headroom than the BT100’s 12V-only, 2000 CCA limit. The TOPDON BT100 is the runner-up and a solid 12V-only tester for anyone who never touches a 24V battery.
If you’re on the fence, just ask yourself one question: do you ever test a 24V battery? If yes, the BT60 PRO is the only one that can do it, so the decision is made. If you’re strictly 12V, the compact BT100 is the simpler grab-and-go choice.
