Maximize Battery Performance with Auto Meter SB-300 Intelligent Handheld Battery Tester Review

Thank you for a well thought out and easy to use product. We have used this to test a range of deep cycle batteries and car batteries that we use in high power electronic astronomy equipment. This has allowed us to easily identify and isolate bad batteries and work flawlessly in the field hundreds of miles away. Nothing compares to a dead battery appearing out of nowhere from miles away!

There were other batteries/results in memory. There is no way to clear the memory. You must set up a test type, run the test, set it up again, and run another test. Then it has two batteries listed in memory when it only has one battery. The AH capacitance reading is too high. Reading the CCA seems reasonable. The same battery performed well in one test and poorly in another. Anyone who understands batteries will see what it is. . . Garbage. The print option has not been tested as I do not need

That's probably too much for any home mechanic unless you work on all of your friends' cars or have a few dying car batteries. In my ideal world, this device could do many other things and help you diagnose and test electrical problems in your vehicle. But that's not how these things work. This is a professional, sophisticated and easy to use battery tester. This is the exact unit they used the last time I drove my car into the Autozone to fix a battery issue. It shows you the capacity…

Here's what my husband said after using this battery tester: It's definitely made for parts shops/small mechanics. The menus are easy to use and allow you to enter address information if you wish. I was very impressed by the name AutoMeter and the nice protective rubber on the outside. I hooked it up to a cold battery that hadn't been used in almost 2 years and it turned out to be still fine but needed a charge. Then I went to a battery of the same age that had been sitting for about 6 months…

This is a very simple battery tester for 6 and 12 volt batteries. It easily checks voltage and CCA. Right off the bat, one of the differences I noticed between this and other battery testers is that this one uses a 9 volt battery to start the testing process. Everything about this particular tester makes it easy to use except for the 9 volt battery which is located behind the screw compartment. It is easily accessible with a regular Phillips screwdriver. The cables are well covered and…

This is the same tool many professional garages use to test battery capacity under load. The battery can still hold a good charge, but what matters is how it behaves under load. For example, I have an old battery in my garage that my brother likes to keep charged so he can connect 12V peripherals to it. Testing of this battery showed a 99% charge, but it also showed as Bad Battery Replace Now. As a previously licensed Registered Mechanic, it is important to be able to show a customer that their

My brother in law is an electrical troubleshooting engineer at Learjet and I gave him this battery tester as he also repairs cars and motorcycles. He is therefore familiar with many mechanical disciplines. Minutes after trying it, he was immediately struck by its intuitive simplicity. First off, the little printed manual that came with it was very well written and easy to understand (even for a novice like me with no experience). Reading the manual explains exactly how the various tests are…
