Volt Vault Battery Organizer With Battery Tester | $11 | Daily Steals | Promo code KJBATTERY

This isn’t the first or the most popular battery organizer box we’ve posted on this website, but at $11 (with promo code KJBATTERY), it is the cheapest, and it even comes with a built-in battery tester. Just note that it’s only designed for AAs and AAAs, whereas those other boxes can often hold Cs, Ds, and 9Vs. But when’s the last time you used any of those?
