    Takes a little while to learn all of the operating modes but beside charging lithium and nickel chemistry batteries, the BT-3400 also does a good job of refreshing (important for nickel chemistry batteries that have been sitting for a while) as well as determining the remaining amp-hour capacity of whatever batteries it can accept. It’s quite consistent in what capacities it reported for a few random batteries I had it test.

    Timely arrival and product works as expected. It condition was in original package and unopened. This was the best value I found for this product. Product was not damaged and perfect in appearance. I would recommend this product. It is an excellent charger and seller.

    The battery charger is extremely extremely useful. I could do a bunch of different things, including reviving old batteries and even tell you whether or not they’re even still livable it just takes time. And by time I mean, it takes hours and sometimes even days but it’s well worth it just to not have to keep buying batteries, especially when you have good rechargeable ones that just need a quick kick
