This is my honest review of the COMECASE 148 Battery Organizer Storage Box/Carrying Case. I personally purchased and used this battery organizer. As with all of my reviews, it’s something I use myself – firsthand.
A Battery Organizer – Is This Really Survival Gear?
I wanted to address this upfront. First, I review gear and gadgets. That may mean survival gear, or it may mean gear for prepping. It might even be something that I find so convenient that I just had to share it.
A battery organizer is survival gear because it is a useful piece of kit for prepping.
A Battery Organizer Is A Prepping Tool
Like everyone else, I had a “battery drawer.” I wish I had thought to snap a photo of my old battery drawer before I organized the batteries, but I didn’t know I’d be writing a product review on it at the time.
It was a mess—heavy batteries of all types rolling around like a game of marbles. Marbles were actually a thing when I was a kid.
I tried various plastic cases, but most of them were in my various packs, where they still live. For the most part, I tried to keep many of the batteries in their original package.
Anyone that’s seen my Prepper Pantry Tour knows I’m big into the organization. Or my device charging station or blackout kit. I HAVE to stay organized, or I feel uneasy.
The Best Prepping Inventory Tools Are “In Plain Sight”
As I showed in Prepper Pantry Plain Sight Inventory System, the best inventory method FOR ME is plain sight. Inventory apps, sheets, databases, well, no, thank you.
The COMECASE battery organizer storage case lets me see exactly what I have and what I need. For example, I didn’t realize I had that many 9-volt batteries. I actually bought more 9-volt batteries for last week’s time change to replace our smoke and CO2 detector batteries. It turns out I already had plenty.
Even though I have over 30 AA and 20 AAA batteries, I want more in my preps. I also have plenty of rechargeable batteries and batteries in my packs, but those are for another article someday.

My COMECASE Battery Organizer Storage Box Product Review

Brand: Comecase
Asin: B07GSLW9CM | Model: 6543877185 | MPN: 6543877185 | Ean: 0634759470748 | UPC: 0634759470748 | ePID: 22031379050 | Part: 2019AJWZKLQ
Now that I explained why we might want a battery organizer and why I’m reviewing it let’s get on with the review.
The Case
The case itself is solid. I mean, it isn’t solid plastic. It just feels solid. The case outside cover is an HQ EVA (Ethylene Vinyl Acetate) material that you see in some children’s furniture, puzzles, and durable toys.
Inside/underneath the case top are four pockets nice for storing flat items such as notes, blister packs, and button/coin size batteries in small envelopes.
The Zipper
While it doesn’t appear to be YKK zippers, the flexible zippers do look sturdy enough. I haven’t had any trouble, but honestly, the zipper is a potential weak spot.

The Foam Battery Organizer
The removable foam insert comes with pre-cut holes for the various batteries. You will need to “pop-out” the plugs exposing the battery cutouts.

In total, the “large” case holds 148 batteries. That’s the size battery organizer case I bought, so that’s the size I’m reviewing. The case currently comes in six different sizes/variations.

The foam cut-outs go all the way through. I dropped it this morning trying to get my featured image photo and was pleased to see only a couple of D-size batteries flew out of the case. The entire foam insert with the batteries came out of the case, but most of the batteries stayed intact – saving me the trouble of putting it all back.
Battery Case Dimensions
For me, the large battery organizer’s case dimensions are perfect to fit in the same drawer I had all the batteries primarily loose. The case dimensions I have with the number of batteries I have stored for the moment are L 9.5″ x W 13.5″ x D 3″.

Odd-Sized Batteries
Many of us preppers fell into the CR123 and 18650 battery craze when buying gear a few years ago. I’ve since tried to reel things back into the AA and AAA batteries, for the most part. This is for better availability when things get scarce.
I also like the USB charging option on most modern devices and battery-driven gear such as radios and flashlights.

With that said, I still have a few of those odd-sized batteries lying around.
As you can see, I can easily get eighteen (18) CR123 batteries into the case without touching the AAA or AA battery spots.
Regarding the 18650 batteries, you can fit a few in, but you will need to use up spaces designed for other batteries.
The height of the 18650 battery, about ¼ inch taller than a D-size battery, isn’t a problem. The case closes just fine.
The 18650 fits VERY snuggly in a AA slot and very loose in a C-size battery slot. None of it’s ideal.
Product packaging / Shipping
I purchased the Comecase Battery Organizer through Amazon. It took just two days from the time I ordered to delivery. I’m in SE Michigan – location and availability affect delivery times so that may not be typical.

The product arrived intact without damage. It was shipped in an Amazon shipping bag. The battery case was enclosed in a zippered clear plastic pouch and wrapped in a clear plastic bag.
Product Warranty
My Amazon order details showed it was “Return eligible” for thirty days.
I can’t find a manufacturer’s website or warranty, although their products are offered on Amazon, Walmart, eBay, and Sears.
Amazon Rating And Reviews
At the time of my review, the Comecase Battery Organizer has 10,298 ratings with 4.7 out of 5 stars. It also has a ‘B‘ Fakespot rating. I give it 4.8 stars.
Out of the Amazon reviews, from a glance, it seems that the biggest complaint is the battery tester, other than shipping issues. I agree, it is cheap, but it is also quick and easy to use. Personally, I didn’t purchase the case for the tester.
Other complaints are the handle is on the wrong side, which I don’t get and is too expensive. It’s under $25 at the time of this review.
Overall Product Review Score – Pros And Cons
Pros | Cons |
✔ Super easy storage and organization. ✔ Easy “In plain sight” inventory. ✔ Nicely designed and well thought out. ✔ Batteries are held snuggly, and when closed, everything stays put. ✔ Swift shipping. ✔ Thirty-day Amazon returns eligible. ✔ Room for an additional 18 CR123 (Or similar)batteries. | ✘ A little expensive. ✘ Little flexibility as to size and number of batteries. ✘ It’s made in China. ✘ Not 18650 battery friendly. ✘ Low-end battery tester. |
After using the case for a while, my overall impression is it’s a quality product, and I would repurchase it if I lost this one.
Other Battery Organizer Options
The last thing I want to mention is that there are many different options for battery organizers. The Comecase happens to be the case I chose and purchased.
I’m seriously thinking about buying the Ontel Battery Daddy 180 Battery Organizer. Not as a replacement but as a second organizer for a BOL. I just added it to my Amazon wishlist. We’ll see if it goes on a Lightning Deal now. Just a little trick of mine. It’s still a nice deal at twenty bucks, anyway. I’ll get a review out on it as soon as I’ve had a chance to buy and test it.
Stay safe. Stay prepared.
