The downside...
I purchased a good amount of rechargeable batteries & a charger to replace all of the batteries I use. I have 3 D-cell Maglites(1-4 cell & 2-3 cell) & a Satellite radio boom box that uses 8 D-cells. I had to purchase another type of sleeve due to the small contact area on the bottom of AA batteries that fit in this sleeve.  The batteries slip thru the spring in the Maglites & the springs in the boom box are too strong & kept slipping off the contact. You need a solid bottom sleeve for these 2 applications. I use 1 solid bottom sleeve at the spring & put these sleeves above. Otherwise they work for my other applications. Just make sure you check out your applications before you order. Saves on headaches later.
