Schumacher Electric Battery Load Tester, 6V/12V – BT-100

Works perfect. I was able to load test my batteries and it worked as described. A must have if you have 12 volt batteries.

Works great !!! I would buy it again.

I bought this to replace one of the exact same model that I bought probably 20 years or so ago. The other one was damaged by my carelessness and was still working great after all these years. It is a great way to put a "load" on a battery to test for weak or damaged cells and will quickly let you know if the battery is the problem or whether I should look elsewhere.

This unit is the old-fashioned type of unit that was used back in the 1960's. It is fool-proof, rugged, and well built. No electronics to go bad like the more expensive units on the market today. Easy, simple, and real to use. Highly recommend.

I use this battery load tester to see the condition of my car battery and it is good for testing your solar system batteries

The Schumacher BT-100 Battery Load Tester and Voltmeter can be used by anyone that can read. When I turned the key on my zero turn mower, sometimes nothing would happen, sometimes it would turn over real slow but would start the mower and other times the mower started no problem. I suspected the battery needed to be replaced but my voltmeter always read about 12 volts so I wasn't 100% sure. In the past I would drive about 25 miles to take the battery to have it tested and buy a new one. They tested the battery with something that looked like this Load Tester so I figured I could do it if I had one of those things. I searched the internet for "battery tester" and found one for 60 + dollars that did just that - test the battery with no load on it. Than I ran across a "battery load tester" for 50 + dollars. That is where I learned that although a battery can read 12 volts, it should actually read about 12.4 volts or higher and that is where the Load Tester comes to play. When I put a load on my mower battery it dropped down in the red below the 12V mark and needed to be replaced. I think I only paid about 30 + dollars for the Schumacher BT-100 Battery Load Tester and Voltmeter. It also can test the charging system and starter motor. This is probably the best $30+ I have spent in a long time. I'm sorry I didn't get one of these many moons ago.

Very accurate reading on the voltage as I got a second opinion when I had to return my battery. It's all not bulky so very easy to store.

This is a great tester. Battery voltage alone is not enough to ensure your battery is still healthy. I’ve used this on cars and a boat.

Excelente producto, muy buen precio, funciona de maravilla le recomiendo ampliamente, quede muy satisfecho con su funcionamiento, no se arrepentira Saludos!

Facile d'utilisation et exécute un vrai test de charge (load test) et non pas juste la lecture du voltage j'ai testé plusieurs batteries et ce testeur confirme l'état correct Je recommande cet outil Important respecter les consignes de sécurité et les instructions (10 sec par test max)

I have many batteries at home for bikes cars camping and boat. I have used a similar style of tester for many years as a truck mechanic and are a fantastic product. I had a cheap digital tester but this didn't last two years. Avoid the digital and buy this mechanical style and it will give you years or service.

Very Good easy to use almost self explanatory.

Cannot go wrong with this one, Schumacher BT-100 is the leader and it is for a reason. Quality tool and from a very reliable company, cannot go wrong here every shade tree mechanic should have one on hand. Cheers.
