PBT-300

This model is simple and easy to get accurate results. The concepts are easy to understand, without going into too much interpretation. Pretty much go or no go. Important to make solid connections. The battery measuring can be greatly effected, if connections are not well made. For example, a bolt loosely threaded into a side post battery showed the battery to be junk. Adding a nut and tightening it gave a good result. It is that sensitive! It gives an actual value of cold cranking amps, along with the go/no go indicator. Alternator and starter testing are a simple test and yields voltage readings which can be used to determine if a component is "on the edge" of good/bad or defective. The price is reasonable and even a novice can save money by not replacing parts that may or may not be defective. It will pay for itself quickly.

Excelente, lo recomiendo para uso contínuo, tengo 10 años usándolo y sigue funcionando sin ningún problema

Measures output in increments of twenty CCA. The shop I work in has a more expensive midtronics battery tester that will tell you the battery is ok but should be replaced soon. This tester would say the same battery needs to be replaced. I wish it were a little more precise but it performs well and I am pleased. Yes I would recommend this to a friend.

Battery tester works as stated. CCA settings, however, do no line up with all battery ratings. Settings are in increments of 20 and does not line up with my battery rating.. My battery is 750 and I had a choice of 740 or 760. Go figure??

Excellent test equipment. But test leads a bit short. Still did OK.

A commercial version of this unit is used by the Telecomm industry to test large Central Office batteries. This PBT300 works great for testing auto batteries. It seems to be very accurate. The Start-Voltage-Drop test function works well and is perfect for testing battery condition and could also test battery cables if attached to the starting motor and engine block. It can also determine the condition of the Alternator charging system. Use of this tester is a great way to determine when your battery is nearing it's end of life. You can replace the battery BEFORE it fails and leaves you stranded.

I purchased this in August of 2019 I used it to service batteries on a mountain where we have a internet broadcasting tower. It has had to be used three times on a system that contains 7 D29 deep cycle batteries. The meter failed and only reads CONN on the display. I called customer support and was informed that I need to send it in for a cost of 109. and change. The company would not even tell me how to open it so I could replace the failed component myself. This is a known problem with this meter. It's true Do not made in America electronics if you want it to last.

This tester is expensive for what it does, but I trust it and it is simple to use. It is almost unchanged in the twelve years since I bought my last one, which only broke when it got run over.
