The batts are no longer 1.3Ah, 2Ah they are 3Ah panasonic, and because its
brushless you get double the runtime.
So 2.5x the capacity of the old 1.3Ah cells, and double the runtime = 5x longer than you are thinking!
Remember also its only a 3 inch grinder and thin disks!
And that I have 4x 3Ah batteries and a 4A charger.

The other thing is hobby stuff. I am always fitting switches, cutting bits of metal, shortening a shaft, cutting bits of plastic, or carbon fibre (outside down wind! DONT breath carbon or glass dust!) etc, So this tiny light grinder should be fine! I cant handle the weight of big grinders, easily sat in a chair. This one is so light and small I will use it to open parcels, and anything else. It will be sat on my bench and used a LOT!
