I can not evaluate the battery itself, because the does not fit in my equipment. This brings me already about the problem, I still have some older devices (about 2-3 years old). But these are probably still in the first generation of 18 V machines, which are not a so-called Makstar. So a yellow base or black base with Star. I have both on my cordless impact wrench, the jigsaw and even with the lawn trimmer everywhere still the old black base without the star. Because of this battery does not fit, although it looks almost identical. Only on the guide rails is a small nose too much off, preventing the insertion of the end in the machine. Here are would make a much more obvious Makita difference (eg, a different color battery, green, blue or red as before in the 12 V devices.) So you have but now seen almost no chance that the battery fits on his device or not.
My mediocre rating thus relates only to the incompatibility to old devices with the old base. Unfortunately, that is not in the product description, nor could I find this information anywhere else on the Internet. Too bad, because I'm actually a real Makita fan. But what the list because the interface points with the battery at the time, is ne mess.
