Best 6V Batteries of 2025

"I was checking my flashlights as I do every year due to frequent power outages. I ordered this battery, and it was reasonably priced. I don't prefer using candles during outages because of my curious cat. The battery arrived quickly, and my package was in perfect condition. It was easy to install in my large flashlight, and it worked immediately. I'm considering buying more for my family since they are affordable and function well."

"This battery is exactly what I needed for my mom's old lantern flashlight, which I haven't used in a while. I couldn't find this type of battery in stores, so ordering online was my best option. Once it arrived, I placed it in the flashlight and turned it on. It worked great, just as I expected, and I'm glad to have it for future power outages."

"I placed these batteries in my emergency lanterns, and they have proven to be a reliable power source at a great price. They last a long time, which is exactly what I need in case of emergencies."

"I've found these batteries to be far superior to cheaper brands. They've been in my deer feeder for five months and still functioning well."

"I find the battery life incredible. I won't buy another brand again. Interstate batteries are truly the best quality for your money!"

"I've always trusted this brand for my motorcycles, but I noticed this particular battery didn't last as long in my flashlight. Still a decent brand overall."

"Both batteries work great. Our 6v cars are now better than new after adding these."

"So far, it works fine. I had to splice the wires from the 6v car to the battery, and I needed to heat up the glue on the old battery to pull the connectors off."

"In my business, we rely on Torrey scales that need these batteries. After replacing old batteries with these, they worked perfectly. The terminals are a bit thin, so I had to clamp down on the wires for a snug fit. However, for the price, I'm satisfied."

"I needed to replace the batteries in my vector spotlight, and this one works just fine. I'd definitely purchase this brand from this company again."

"I bought these for my dog's shock collar. They last forever and are a great value for money."

"I absolutely love these batteries. They outperform traditional heavy batteries. Highly recommend!"

"I used them in an old US Navy battle lantern, and they are as bright as the originals. However, installing them can be a bit tricky due to the fragile spring contacts. I’ll be careful during recharges."

"Unfortunately, while local batteries lasted at least a month in my game feeder, these only lasted about a week each. I won't bother using the rest; it feels like a total waste of money."

"I was disappointed because the ad said it came with 6 batteries, but I only received one. This feels like false advertising."
