Best 6V Batteries of 2026

"I needed a new battery for my lantern and this one worked out perfectly. Just in time for a power outage, my light was ready to go with the new battery installed. Performance is great."

"I ordered two batteries in December 2025, and both came with a 'best by' date well into 2030. They work as expected and the shelf life gives me peace of mind."

"While it took almost a month to arrive, the battery measured nearly 7 volts out of the box and has a 'best by' date of December 2030. I'm satisfied with the purchase."

"I was really happy to find this battery at a good price, and the installation was fast. Now my flashlight is working again, which is a relief!"

"I bought these batteries specifically for my lantern torch in a remote location. Unfortunately, one arrived dead and possibly expired, so I hope to get a replacement or refund."

"These batteries are great for backup flashlights during power outages. They're affordable and easy to keep in the kitchen drawer or on the counter for quick access."

"I've used these batteries several times and they work just as well as the more expensive versions. For the price, it's a great deal and they fit my dog's collar perfectly."

"The batteries are simple to install and fit securely in the collar. While they don't last quite as long as the name brand, the lower cost makes them a solid investment for me."

"Some of these batteries lasted about two months, but a few needed to be replaced within days. If you rely on the collar for your dog's safety, the original brand may be a safer choice, but the price on these is hard to beat if you don't mind some inconsistency."

"I’ve found these batteries to be extremely reliable and they’ve performed just as expected. Charging is quick, they maintain a steady charge, and provide consistent power for my devices. I also like the maintenance-free, sealed construction—it’s safe and convenient. The 6-pack option is a real bonus for keeping spares handy or replacing several batteries at once. Everything arrived well-packaged and ready to use. Overall, a great value for dependable 6V batteries."

"The battery was delivered quickly and installation was a breeze. After charging, the error message on my security panel disappeared right away. It would have been nice to have instructions for recycling the old battery, but otherwise, I’m very satisfied with the product."

"I put one of these batteries in my child’s electric motorcycle and it worked perfectly from the start. The bike now runs smoothly and the battery holds its charge well. I’m very happy with this purchase and would definitely recommend it to others."

"I've used this battery with my Moultrie feeders and am impressed by its reliable, steady power and long charge retention, even through changing outdoor temperatures. The tab-top design makes it quick and easy to install. It's definitely a well-built, dependable choice for outdoor use."

"After running my Moultrie Pro III deer feeder for over two months—three feedings per day—I'm only now needing to recharge it for the first time. Ordering was fast and convenient, and I'd definitely purchase again!"

"While I preferred the old battery with gator clips for easier connections, this one still gets the job done and keeps my feeder running smoothly."

"This battery has been a real game-changer for my Streamlight Strion. It delivers powerful, long-lasting performance and charges quickly when needed. The quality is what you'd expect from Streamlight. Although it costs a bit more than generic brands, the reliability and lifespan make it worth it."

"I got over 6 years and thousands of charge cycles from my original Strion HL LED battery, so I stuck with Streamlight for my replacement. It arrived fast and worked perfectly out of the box. Streamlight’s reliability keeps me coming back—even for my rifle lights."

"These are authentic OEM batteries, not aftermarket. I recommend them to anyone who wants their light to work like new. Investing in the original battery really pays off for both performance and peace of mind."

"I've been using these batteries in my deer feeder, and so far, they've been lasting several weeks without any problems and still show full power on the feeder timer. Plus, they're much less expensive than the big brands."

"I use these mostly for my wireless guitar controller and they do the job just fine. Since I only play occasionally for about an hour or two, they last well enough for my needs. For heavier use, you might need something stronger, but for me, they're perfectly fine and affordable."

"I was disappointed with these D cells. A few arrived with dents and didn’t last as long as other brands in my electric candles. I usually get about 90 days with Varta or Duracell, but only 30-40 days with these. Still, the price is low, so it might be a trade-off."

"I was a bit skeptical about trying a non-brand battery for my PetSafe collars, but the price for the 10-pack is unbeatable. They fit just right and the performance matches the originals. With how many batteries my collars use, this is a cost-effective solution that doesn't compromise on quality. I'm definitely sticking with these from now on."

"Replacing the battery in my dog's collar was quick and hassle-free. As soon as I put in the new battery, the collar worked perfectly again and my dog stayed within her boundaries. I'll check back in a month or so to see how long the battery lasts, but so far, no issues at all."

"I purchased these for my two dogs' boundary collars, but unfortunately, I ran into some issues. Several batteries were dead right out of the pack, and the rest only lasted a short while. Maybe I just got a bad batch, but I went through the entire pack in about a week."

"I've only used them briefly, but they work perfectly in my device. No complaints so far."

"These batteries are exactly the right size for my dog's bark collar—they fit completely and seem to last for a long time!"

"I recently picked up this battery, and it functions well with my Canon AE-1 Program camera."

"This battery was a real lifesaver for my child’s ride-on car. It fit perfectly and was incredibly easy to install—there were no confusing instructions, and my kid was back to playing in minutes!"

"I grabbed this battery to swap out the old one in my toddler’s Audi R8 Spyder ride-on, and installing it was a breeze—about five minutes with zero extra tools or parts needed. The fit was spot-on, and the quality feels solid. Great value for what I paid!"

"I used these to replace batteries in my CyberPower UPS. While the price was fantastic and the batteries were a close match, they were just a touch taller than my originals, so the tray doesn’t quite close all the way. Not a huge deal, but something to know for UPS use."
