Basic battery load tester.
I have used this type of tester for many many years. This works just fine. For diy people, read instructions thoroughly. It works.

Decent load tester with the old fashioned large resistor
I just don't know how to trust the new compact load testers with digital readouts. According to physics, to load test, you must place a small valued, high power resistor across the two terminals that results in a large amount of current between them, then monitor voltage drop or current and see if the battery can provide a sustained amount of either. This box does exactly that, and the heat you will feel will confirm to you that without doubt, a large amount of power traversed its two terminals. The readings I tried on several batteries (one dead) seemed to confirm the status of each.

Low Tech But Works Great and is All You Need
No complaints with this one. I checked both my motorcycle and car battery successfully. Diagnosed a bad motorcycle battery and a good car battery. Problem with the car was the alternator, not the battery.

Seems good and have used it alot
Ive used it alot since ive owned it trying it on every battery i have. Whether its telling me the truth or not i have no idea how to verify that it gives accurate readings but for now im just going to believe that it is.
