Review: Easy to use and understand. Well made, and does everything you need it to do. - The connectors seem really well made and are larger than what you find on a lot of battery chargers which make fitting on the battery terminal much easier. The device powers on quickly and was very simple to use. I didn't even read the directions the first time I used it. Very easy to get the information you need on batteries state of charge and perform a cranking amp test. I think I'm going to use this on all my batteries before winter every year and hopefully save myself the hassle of getting stranded which the first cold snap that finishes off an already weakened battery.
Review: Everyone should have their own!! - Accurate and easy! This FOXWELL BT100 Pro is a lifesaver. It quickly diagnosed a bad cell in my truck battery that the local shop missed. It's simple to use, works on AGM and GEL, and the backlit screen is very clear. Essential tool for any one to use!!

### ⭐⭐⭐⭐⭐ Everyone should have their own!!

Accurate and easy! This FOXWELL BT100 Pro is a lifesaver. It quickly diagnosed a bad cell in my truck battery that the local shop missed. It's simple to use, works on AGM and GEL, and the backlit screen is very clear. Essential tool for any one to use!!

### ⭐⭐⭐⭐⭐ Handy easy to use tool, used many times!
*by J***R on November 8, 2025*

This is a very handy tester that works well and is very easy to use. Yes, they will do the same sort of test at AutoZone, O'Reilly, Advance Auto but it is still handy to have in your toolbox. Only negative to it I found is that while it does give a test result for internal resistance denoted as "RES." on the screen, the manual doesn't give any information about what that is or what good, average or bad reading would be.
