Bought something similar from Amazon, liked it so much bought another for work. Very handy and the battery tester seems to be accurate.

If any of you simply want storage without the need for a tender, I recommend Storacell.

I have a bunch of them for different types of batteries & the size makes them very manageable and stashable around the places they're likely to be needed.

The wife just ordered one for us. It's supposed to arrive tomorrow. Yes, we use a cardboard box. but on the piano bench is a card of 18 AA's. If lucky, I'll be able to separate the Alkaline from the Lithium cells. I do like the lithium cells because the last significantly longer. Probably a better buy, definately less trouble than having them go flat in the middle of something. I don't even remember what kind are in my first line flashlight, but they last a real long time.
