# Put the spare batteries where you will see them > A spare battery on a shelf is a battery you forget. We walk through where to park your AA stash so the cells stay fresh and you actually use them before they age out. Part of the [Power](https://bordernest.com/silo/power.md) guides. ## Why the shelf is the wrong place A brick of AAs in a hot garage is a brick you forget about until the cells are tired and the device you needed is dead. Heat and stillness are both enemies of stored alkaline cells, and a closed drawer hides them from the very moment you need them most. The fix is simple and a little counterintuitive: keep the spare pack next to the device that uses it, inside the house, where you walk past it every day. ## Rotate the older cells into something low stakes Twice a year, take the older pack and spend those cells on a remote control, a kid's toy, or a clock that runs through them slowly. That rotation does two jobs at once. It keeps the stash in your main drawer made of newer cells, and it makes sure no battery sits long enough to leak or lose its charge on its own. Think of it like a pantry: first in, first out, with a clear label on the front. ## Match the battery to the device before you buy Before you click buy, open the battery door and read the size printed inside. AAs and AAAs look almost the same in a photo, and the wrong cell will not just fail, it can bend the contact spring. If the door is missing its label, a quick photo with your phone and a side-by-side comparison at the store saves a return trip. ## Do this today Walk to wherever your spare batteries live right now. Pull the pack out, check the date on the back, and move it to a spot you actually see, like a kitchen drawer beside the flashlight or the kitchen scale. Then set a phone reminder for six months from now to rotate the older cells into a remote. **Energizer: Energizer MAX AA Batteries, 24 count.** Park this AA pack beside something that actually takes AA so the cells get used before they age out. ## Build on this Batteries before the power station is the next guide, and it walks through sizing the cells that feed your flashlights and radios so the power station is the second purchase, not the first.
