To check your batteries, simply place the battery on the tester, aligning the positive and negative symbols. The small screen then clearly and accurately shows if the battery needs to be recycled or if it still has some life to it. The only downside to the battery organizer, it seems, is that some reviewers point out that there isn’t a latch on the lid, meaning it could lead to spilled batteries if dropped. Otherwise, shoppers say the case has made such an impact on their tidying skills that it’s the “best organizer ever.” Plus, it’s less than $20.
