Battery Organizer Holder, 200+ Batteries Storage Containers Box Case with Tester Checker BT-168...

Its a good quality battery organizer holder. The included battery tester is not very accurate, but it still gets the job done. Using a multimeter would be a better option for accurate testing.
Some CR2 lithium cells may not fit in the available slots, but the C battery slots can be used as an alternative. It may be a loose fit, but at least there is a place to store those batteries.
Overall, this organizer is much better than just keeping batteries in a shoe box and having to search through them. No regrets on this purchase as it helps...
