Feature Points
  • Tests flooded, deep cycle, and AGM batteries with CCA range of 100-1600 - also detects discharged batteries, bad cells, and has built in reverse polarity protection.
  • This tester applies a true 40 amp load to the battery in order to simulate real world operating conditions consistent with BCI (Battery Council International) testing standards.
  • Battery test results include: Measured true CCA, voltage and percent of charge, and the battery's state of health (good, near end of life, or bad).
  • Automatically stores the last 100 tests in memory.
  • 30" - 16 gauge leads with professional grade clamps that are easily field serviceable.
  • Customer communication with optional PR-12 (external printer), PR-20 (bolt-on printer), or AC-12 (PC cable).

The literature says the SB-300 determines the battery's state of health (three categories). I would like to know: what are the details for making that determination? Instinctively, I distrust anything that gives good/bad verdict.

Asked by: Bernie
Thank you for your inquiry. The SB-300 Uses a microprocessor to apply a pulsed 40 amp load to the battery, Using data derived from this as well as measuring battery temperature, a proprietary series of calculations determines battery condition.

Can a older model be updated from 2.5 v ? The tester that I have doesn't have a option available for AGM type battery or change from CCA to AH ratings.

Asked by: extrapilot
Thank you for your question. Unfortunately, there is no way to update older units to a newer version.

does the tester check alternator output and starter draw?

Asked by: hugh
Thank you for your question. No this unit cannot test alternator output or starter draw. The BVA-300 and BVA-350 would be the two model handheld testers we offer that are capable of testing alternator output and starter draw.

I have a auto meter BVA-300. How do I determine the batterie's temperature? The meter ask for the battery temperature when performing the battery test.

Asked by: Rod 14
Thank you for your inquiry. When using the BVA-300, you simply estimate and enter ambient temperature. So for example if the battery is still in the vehicle, and it has been sitting outside in 32 degree weather, that is the temperature you would enter.

Hi ..we use numerous Odessey PC1800-FT AGM (CCA 1300), 214 Ah batteries in our broadcast vehicles. Which of your testers would give us a reasonable idea of general condition, life remaining etc.?

Asked by: DaveDci001
Hi Dave, thank you for the question. The SB-300 will provide the tests you're looking for. If you're looking to test starter draw or alternators, then you'd want to look at other models like the BVA-300.
