Best Battery Holders of 2026

"I used this to repair my old Gossen light meter, and now it works flawlessly. The plastic-encased connectors don’t swivel like the old vinyl ones, which completely solved my connection issue. Much more reliable than the original part."

"This battery connector worked perfectly to fix my active bass guitar after the original corroded. The wires are a good length, and the hard connector feels sturdier than the typical soft style. I even received an extra piece in the pack."

"I replaced a broken battery connector on my guitar preamp with this, and the rigid plastic shell is a clear upgrade over the flexible original. It’s a noticeable improvement in quality."

"I used this to fix my garage door opener and found the product to be very durable and straightforward for anyone with a bit of DIY experience. For the price, it's a great value and has worked flawlessly since installation."

"I purchased the 2-pack for a lightsaber project. The connectors are sturdy and the wires are just the right thickness—not flimsy, but flexible. They fit snugly on the battery, providing a secure connection. If you need reliability for small electronics, these work really well."

"These connectors performed great for my project, but I noticed they corroded pretty quickly when left outside. Just something to keep in mind, though overall they did the job."

"I needed a 9v battery holder with a switch and leads for my project. This fit the requirements perfectly and was affordably priced. While it comes with a tiny screw for the sliding cover, I found the cover stays on just fine without it. Others might prefer to use the screw for extra security."

"I use these for Halloween animatronics and they’re super easy to set up and wire. The leads are a good length, and everything matches what’s shown in the pictures."

"I'm really impressed with the quality—these made carrying spare batteries for my speed lights much easier. No more loose batteries in my bag!"

"I store hundreds of C batteries for engineering equipment, and these boxes keep them secure, dry, and stop the terminals from touching during transport in our vans and trucks. Perfect for our needs!"

"We buy batteries in bulk, so after opening the original packaging, it's hard to keep things organized. These containers are a game-changer for storage—I even use the divider to separate dead batteries. I just wish the materials were a bit sturdier for the price, but they still get the job done."

"I was genuinely surprised at how well-built and versatile these battery holders are. I used one to power a hologram device that needed 5V and it worked flawlessly—just plug and play, no issues at all. For the price, it's a reliable and affordable solution for low voltage, USB-powered projects."

"These holders were perfect for my Arduino and LED strip projects. The sturdy plastic and secure snap-on cover really impressed me, and the on/off switch is super handy. The output is consistent with both rechargeable and alkaline batteries. I also like that it comes as a two-pack—one is now in a homemade flashlight, the other in a desktop fan. Highly recommended for electronics hobbyists!"

"I needed a safe and lightweight way to power my kid's Halloween costume LEDs, and these were exactly what I was looking for. I didn't want to use a bulky power bank, especially in wet conditions, so this product gave me peace of mind and worked great. It's lightweight, stable, and reusable for other projects too."

"During the holiday season, I often end up with partially used AAA batteries, but most of my electronics require AAs. These converters have been a lifesaver, allowing me to use up those batteries instead of tossing them. They’re simple to use, just insert the battery and cap it, paying attention to the + and - ends. I was worried about device compatibility, but so far, everything works smoothly. This has really helped reduce waste and made sure I get the most out of every battery."

"I mainly use rechargeable batteries, which can get pricey, so discovering these sleeves was a game changer. Now, I just buy AAA batteries and use these to make them work as AAs. It’s so much easier, cheaper, and saves space. I’ve been using them for months with no issues—they work just like regular AA batteries. Definitely planning to buy more and would recommend them to anyone looking for a clever solution!"

"The converters are well-made and seem reliable. However, they’re a bit thicker than a standard AA battery, so they didn’t fit in the flashlight I wanted to use. I’ll keep them handy for other gadgets, though, since they look like they’ll come in useful for future projects."
