TOPDON BT600 Battery Tester vs ANCEL BA301 Battery Tester
Which should you buy? Our verdict on both, pulled from our full The Best Car Battery and Load Testers: 4 Compared (and One to Skip) comparison.
The BT600 covers the widest set of battery profiles and the most of the charging circuit, and it prints the result so you have something to hand a customer or keep on file. The BA301 does the same style of conductance test on 6V and 12V lead-acid for far less, if you can live without 24V and without a printer.
TOPDON BT600 Battery Tester
Buy itA conductance tester that covers five lead-acid battery profiles, both 12V and 24V systems, and prints the result on the spot.
- TOPDON states conductivity-based testing with a 100 to 2000 CCA and 30 to 220 Ah range, so it covers everything from a small car to a light truck.
- The spec sheet lists selectable flooded, AGM, Gel, EFB and VRLA profiles plus CCA, CA, BCI, MCA, DIN, IEC, EN, SAE, JIS and GB rating standards.
- Cranking and charging tests run on both 12V and 24V, and a ripple test is listed for 12V, so you can check the alternator as well as the battery.
- No lithium or LiFePO4 support appears anywhere on the product page, so a drop-in LiFePO4 starting battery is out of scope.
- Testing voltage is listed as 12V and 24V, so a 6V motorcycle or classic battery is not the target here.
- A conductance reading infers capacity rather than measuring delivered current, so it can be thrown by surface charge on a freshly charged battery.
ANCEL BA301 Battery Tester
Buy itThe cheapest honest conductance tester in the group, and the only one here that covers 6V as well as 12V lead-acid.
- ANCEL states conductance testing technology for 6V and 12V lead-acid batteries from 100 to 2000 CCA, including flooded, AGM flat plate, AGM spiral, Gel and EFB.
- A one-click waveform function plots the voltage during cranking, which is genuinely useful for spotting a starter that drags rather than a battery that is flat.
- ANCEL says it can test batteries with loss of electricity without a full charge first, and can test them on or off the vehicle.
- No 24V support, so heavy trucks and most marine 24V setups are out.
- No lithium or LiFePO4 listed, and no lithium profile to select.
- The charging system test is described as checking alternator output, but ANCEL does not spell out a ripple measurement the way the BT600 spec sheet does.
