AAA Rechargeable Batteries

With kids in the house, we’re constantly dealing with a battery shortage. From toys to gadgets, it feels like the batteries always run out at the most inconvenient times, especially when the kids find a new favorite toy that eats up batteries quickly. I decided to try rechargeable batteries, and so far, it’s been a fantastic solution. Here’s a detailed review based on our experience: 1. Eliminates the Constant Need for New Batteries One of the biggest advantages of switching to rechargeable batteries is that we no longer have to deal with the endless cycle of buying new batteries every time something dies. With kids constantly playing with battery-powered toys, it felt like we were going through packs of AA and AAA batteries weekly. These rechargeable batteries have put an end to that. Instead of running to the store every time a toy runs out of juice, we just recharge these batteries, and they’re good to go again. 2. Quick Charging Time Another thing I really appreciate about these rechargeable batteries is how quickly they charge. We’ve all been in situations where we need batteries for something urgently, and with some older rechargeable options, charging could take hours. These batteries, however, charge in a reasonable amount of time. Within an hour or two, we have fresh batteries ready to use, which is especially helpful when the kids are eager to get back to playing with their favorite toys. 3. Environmentally Friendly It feels good to be reducing our environmental impact. Instead of throwing away single-use batteries every time they run out, these rechargeable batteries can be used over and over again. It’s a small change, but it makes a difference in cutting down on waste. We’ve definitely noticed a reduction in the number of battery packs we need to dispose of, which is a win for both our household and the environment. 4. Cost-Effective in the Long Run While rechargeable batteries might have a slightly higher upfront cost, they end up being far more cost-effective in the long run. Rather than constantly buying new disposable batteries, we’ve invested in a set of rechargeable batteries and a charging station, and that’s all we need. Over time, this has saved us quite a bit of money. The ability to just pop the batteries into the charger rather than buying new ones all the time makes a big difference, especially with kids who go through batteries so quickly. 5. Durability and Reliability Since switching to rechargeable batteries, we haven’t had any reliability issues. The batteries hold a charge well, and they work just as effectively as regular disposable ones. They have great longevity, lasting through multiple play sessions without any noticeable drop in performance. Whether it’s powering up toys, remotes, or other devices, these batteries consistently deliver. Final Thoughts If you have kids and constantly find yourself scrambling for batteries, rechargeable batteries are a total game changer. They save money, reduce waste, and offer a reliable power source that charges quickly and lasts. No more running to the store for last-minute battery purchases or dealing with piles of dead batteries. With these rechargeable batteries, we’ve found a solution that works for our busy household, and I couldn’t be happier. Highly recommend for anyone looking for a more sustainable and cost-effective battery solution.

Update: I am adding an update and now giving it a full 5 stars (up from 3). I had originally been concerned about having to charge them so often. I wasn't sure if it was the batteries or what I was using them in, since I got them for motion sensitive lights. Customer service contacted me right away wanting to make sure I was happy with the product and see if they could help with my issue. Since I have gotten such great customer service, I am giving them 5 stars and going to try to use them with lights in a less high traffic area. I like them because they are rechargeable, but it seems like I am always having to charge them. Maybe they are not lasting as long because I have them in the kitchen where they are coming on a lot. They work great and I love the extra light. Easy to charge and use.

I use a Powerex Charger to charge my batteries. It's akin to a smart charger that enables refreshing, discharging, and reading the exact capacity of the batteries. 9 batteries showed 900Mah on average and they're working fine, but 3 won't stop charging and I had to manually pull them out to stop the charge. 3 are duds but I still think they're okay in terms of bang for the buck if you plan on using them on non-critical devices, such as remotes and clocks. Just be sure to use name-brand batteries on devices that you depend on to work at all times. UPDATE #1: I received a message from this seller after making this review. I was asked to send a video or photo that best describes the problem. I responded; "Thank you but no thank you" because I wasn't gonna spend an hour recording the charging process and how the 3 duds won't stop charging. Long story short, the seller is serious about their reputation and they do stand behind the quality of their product 100 percent because shortly thereafter, I received a full refund for the purchase of their batteries. From now on, every rechargeable battery I buy will be from this company. The confidence you gain for a product when a seller is this serious about customer satisfaction is unmatched. For what is worth, Powerowl gets my seal of approval. UPDATE #2: Bought another set of 12 on April 4th, 2024. All 12 went through the battery analyzer break-in cycle and all 12 completed the cycle successfully. The capacity for the 12 batteries ranges from 860Mah to 900Mah. If you're wondering about the less-than-advertised capacity, then don't because like it or not this is the industry standard practice. All the name brands will show about 10 to 15 percent less capacity than their advertised claim. I'm not saying that it's a righteous practice, but that that's just the way things are. Except for the 3 from the first purchase, the rest of the batteries are functioning as they should. I still maintain that this brand is a great bang for the buck.

High capacity but it doesn't hold a charge so you need to top them up before you store them away.

Great customer service and awesome batteries. They hold charge for a long time and customer support is top notch.

Work great

Modern backpackers have to not only manage their physical energy budget, but their device energy budget as well, and every ounce counts. Your phone, headlamp, earbuds, perhaps dedicated GPS device, etc. all eat up power. For a weekend trip, that isn't a big deal. Just manage your power consumption, maybe carry a small power pack, and you can always recharge everything on the trip home. But for long-term trips, it isn't practical to carry lots of spare batteries, but the risks from having batteries fail in critical applications like light and navigation can be unacceptably high without them. This is compounded by the fact that I enjoy hiking into the evening, partly because it is cooler in the summer, and partly because the days are so short in the winter. I had used NiMH batteries for a while many years ago, but the high self-discharge rate (1-3% per DAY) and a few weak batteries bit me too often, so I finally went back to alkaline batteries and carrying enough spares. However, I still had excellent NiMH chargers that weren't being used and the new low self-discharge technology was intriguing and seemed to have matured to the point that multiple manufacturers could offer it at decent prices. After buying an eight-pack of the PowerOwl batteries, I wanted to make a less-subjective comparison among my three options - AAA generic alkaline, name-brand alkaline, and PowerOwl NiMH. To measure discharge rate, I used my backpacking headlamp. It is a Coast FL75 running at medium intensity white light and maximum beam dispersal. I hung the lamp 44" from the floor and measured the brightness at floor level using a lux meter app on my phone. This is a fairly harsh test of battery life, but I'm assuming night hiking where I would use those settings for the best balance of battery life and trail visibility. As the graph shows, the generic alkaline battery fared the worst, with only about .5 hour of hiking time and only slightly more usable time. The Duracell provided about .8 hour of hiking time and another 10-15 minutes of usable time. The PowerOwl (after initial full charge) was by far the brightest for the longest time, with almost 1.5 hours of hiking time, and another 10-15 minutes of usable time. When the fact that NiMH batteries do best after a few discharge/charge cycles is factored in, I might be able to get up to two hours of night hiking time with the PowerOwl batteries, which is a major improvement. Obviously, I haven't been able to see how well these do after sitting charged for months, how many charge-discharge cycles they have before their capacity drops too much, or even how the batteries hold up over the years, but for now, this is my go-to solution for backpacking batteries. I'm supplementing the batteries with a very small/light USB-powered NiMH charger I can combine with my tiny USB charger so I can get everything recharged at a hostel or hotel overnight between back-to-back trail section-hikes. With the low-discharge rate, I'll buy and test the AA batteries in computer pointing devices and such. It'll be good to go back to a less wasteful solution for portable power needs.

Low voltage batteries!!! I bought these to use in a couple battery powered "smart" motion sensors. With normal disposable batteries the sensors work perfect. With these rechargeable batteries they don't work at all and give a low battery warning before turning off, even when they're fully charged. I tested the fully charged powerowl batters with my meter and they show 1.2 V. For reference the disposable batters I use show 1.5-1.7 V when brand new. On closer inspection the Powerowl AAA batteries are clearly labeled 1.2 V on the battery wrapper so they are charging to "full" but the problem is that 1.2 V is not enough to power my motion sensors correctly. I am able to use these batteries in my pocket flashlights without issue but the light is slightly dimmer (not a big issue, I wouldn't have noticed it was dimmer if I wasn't comparing them side by side). So if you only need these batteries for a TV remote control or a simple flashlight they're good enough. But if you want to power some higher load "smart" devices these might not work at all.
