For National Preparedness Month, the easiest battery upgrade is not buying more batteries. It is keeping the right sizes visible, tested, and ready before the next outage.
Ready.gov marks September as National Preparedness Month and recommends building an emergency supply kit before a disruption happens. Batteries are one of the small items that decide whether flashlights, radios, lanterns, remotes, and small safety devices actually work when you reach for them.

Quick Answer: What Should a Home Battery Kit Include?
A practical home battery kit should group AA, AAA, C, D, 9V, and coin-cell batteries by size, keep used or untested batteries separate, and place them near flashlights, lanterns, and a printed household checklist.
The ALKOO 269-Slot Battery Organizer Case with Tester is built for this kind of household storage. It gives each battery size a dedicated slot, keeps the case portable with a handle, and makes it easier to check what needs replacing before weather, travel, or seasonal outages.
Why This Topic Matters Now
September is a natural time to check home readiness because U.S. households are moving from summer storm season into fall and winter outage planning. Instead of leaving batteries loose in drawers, a dedicated organizer makes inventory obvious at a glance.
Where to Store It
Keep the organizer in a dry utility closet, garage shelf, office cabinet, or pantry area that adults can access quickly. If you are rebuilding a broader home readiness area, pair it with Home Storage and On-the-Go Essentials cases for flashlights, small tools, and chargers.
Simple 10-Minute Setup
- Collect all loose household batteries from drawers, remotes, toys, cameras, and tool bags.
- Sort by size and separate leaking, expired, or questionable batteries.
- Place fresh batteries into the organizer by size so empty slots show what to restock.
- Keep a flashlight and lantern nearby so the kit has an obvious job.
- Review the kit monthly during storm season or before travel.

FAQ
Should batteries be stored loose in a drawer?
No. Loose storage makes it harder to see sizes and quantities, and it can create contact between terminals. Use original packaging or a dedicated organizer that keeps batteries separated.
How often should I check an emergency battery kit?
Check it at least once per season, and again before major travel, storms, or winter weather.
Do I need every battery size?
Start with the sizes used by your own flashlights, remotes, radios, sensors, and lanterns. AA, AAA, C, D, and 9V are common in home readiness kits.
