Schumacher Electric Digital Battery Tester, BT175, 3-in-1, 12 Volt, for Use with Motorcycle, ATV, Marine, Car, SUV, Truck, RV, and Classic Car Batteries

I have a wide range of batteries from 12ah AGM to 100ah AGMs to keep up with and this works perfectly to know how strong your batteries are. The only draw back I've found is it only goes up to 1200 cranking amps so I can't test my large dual 1600 CCA battery bank or my 2400 CCA battery banks. My bad for not reading the fine print. This tester is great for 95% of users since large battery banks on cars isn't the norm. For big truck battery banks or big equipment battery banks read the fine print on the testers limits in CCA test ability. Other than that it's a excellent tester up to 1200 CCA.

This tester is very easy to use! And accurate!

This is a cool gadget. This will be the 5th season using my 12v Marine cranking battery. Wasnt sure if it was still good so I bought this load tester. Yup it's still good. Wasn't expecting that for a 4 year old battery.

This does the job. Not real impressive. I think the original load testers are better.

I use this professionally as a backup to my otc one and it has all the features I need in a tester. Easy to use and can't be beat for the price.

Works well for testing my car battery

Not sure if this unit is accurate or not. I tested several batteries and the readings seem artificially low. I tested a brand new battery rated at 675 CCA and got 380. I will compare this unit to the car dealers readings and see.It should be used as a relative guide for deminishment of the battery and not an absolute.

Thanks.
