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.

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.

Works great !!! I would buy it again.

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.

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.

All of our local auto stores offer free battery testing but it's a hassle and if a battery tests out bad, I'd feel obligated to buy one from that store as opposed to a better offering. The dual batteries on my truck started getting weak in cooler temps. I tested them after the truck sat for a couple days and came up with 12.05v which I know is just around 50% capacity and I know there aren't any drains. Using this, I determined the batteries weren't bad but they were in fact weak which isn't surprising since they're over 4 years old.The real reason I bought this was for our boat, which has 3 high performance AGM group 31 batteries that cost ~$500/ea and we typically refresh them every 3 years for safety and reliability. They're buried in the hull and not easy to get out, so if they're coming out they're getting replaced. With this I'll be able to more accurately assess the condition of the batteries and replace them when they test weaker than their stated cranking amps as opposed to just a time-based replacement, and the best part is I can leave them right where they are to test them. This is sure to save us money in the long run.The tool is simplistic, feels durable, and should last a long time.

This battery load tester is perfect.no electronic gizmos to break. Just plain old analog simplicity that works every time.

Works wells and fast

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 outilImportant 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.
