### ⭐⭐⭐⭐⭐ nice tester

works great

### ⭐⭐⭐⭐⭐ Great battery checker
*by L***W on July 7, 2025*

Works as stated. I have two of them, one at lake , one at home. Great way to check on the viability of car/ boat batteries. Worth every penny!

### ⭐⭐⭐⭐ Does the job; not quite 100A
*by J***O on August 14, 2023*

Roughly does the task I asked it. A star deducted because not quite a 100A load due to resistance being 0.2 Ohms measured with switch depressed. For my expected voltage range of 12.8V (fully charged lead acid), I can only manage a draw of 64A when cold. I imagine when the resistive element inside gets glowing orange, it's probably less current, as materials become more resistive as they heat up (usually exacerbating the heat until pop goes the wire). The clamps and wire also acts as part of the resistive element and needs to be cooled fully between battery tests or it will become a molten pool. This is why it's on a dead-man switch (when you let go it turns off). So by my figurin', if the gauge is rated for a 100A draw, it's off by 64%! That's not great, but you can just judge how deep it plunges after a load for 15s or so as a pretty good sign if it's toast. Don't think I'll trust the actual gauge, otherwise it's a pretty decent resistive element for high amperage. Wait... if it's off by 64% I might need a battery after all... if ONLY I HAD A TOOL THAT RELIABLY TOLD ME....
