Great product and have 3 sets now. Higher capacity Li-ion AA batteries and chargers. These battery’s are working great and the chargers smart enough to do one or more up to 8 at a time. Our 3 units have given us enough batteries and capacity where we won’t be buying alkaline replacements anymore! Have no failures of batteries or chargers and 5 of more charge cycles so far over last 4 month. Seems durable and these should easily pay for themselves in flashlights, remotes, clocks and holiday novelties over the next year & onward. Recommend!

The charger charges really fast and that's for 8 batteries. I used my USB port on my computer. Batteries last a long time and store well after charging either in the charger or in the device I'm using them which happens to be a transmitter for a RC truck. Well worth the money. They're also compatible with some of my flashlights.

I never thought I’d be happy to get an 8 pack of name brand Lithiums for $11. They’re now $20+ and I was looking for an alternative battery source for my Blink cameras and I found it with this item. These charge fast and last longer than I’m used to with the previous brands. I own two of these because of the overall dollar savings and performance on all my Blink cameras. They’re form fit and can be used just like any other AA battery. The USB-C charge case is solidly built with clear charging status indicators on the lid.

these are 4.2V Li-on batteries with internal controls to regulates it down to 1.5V. this could be a good thing because it will be 1.5V steady voltage untill the battery shuts off. Now the bad thing. this battery will not charge in a regular 4.2V li-on battery charger, unlike other rechargeable AA 1.5V batteries that are also 4.2V li-on rechargeables. I ordered two sets of these AA 1.5V rechargables, - one is a different brand- and one will charge with a li-ion dedicated charger, reads 4.2V, but this one does not, it reads as dead battery. The battery charger I use have digital read out of voltage, amperage , internal resistance and so on. it can charge li-on ni-cad and ni-mh batteries 1.2V to 4.2V Interestingly the other brand of rechargable that is confirmed 4.2V Li-on will charge up in this battery's charging cradle.

Pujimax 4255 mWh Rechargeable AA Lithium Battery Bottom line up front: These batteries don't come anywhere close to what Pujimax advertises. The company uses a misleading unit of measurement to inflate the perceived capacity, makes bold claims about longevity with zero documentation to back them up, and when you reach out for answers, you get stonewalled. Save your money. What They Claim vs. What You Actually Get When I first saw these batteries rated at 4255 mWh, I figured they had to be a solid rechargeable option. That's the reaction Pujimax is counting on. But there's a trick they're pulling with the units of measurement that most people won't catch right away. Battery capacity is standardly measured in milliamp-hours (mAh). Pujimax lists their capacity in milliwatt-hours (mWh) instead. The number looks bigger in mWh, and that's exactly why they do it. Here's the conversion — you just divide by the nominal voltage (1.5V): 4255 mWh ÷ 1.5V = ~2837 mAh So they're claiming roughly 2837 mAh of capacity. Sounds decent on paper. But let me tell you what I actually got when I tested these things. Actual measured capacity: approximately 1000 mAh. That's not even in the same ballpark. That's about 35% of what they advertise. You're getting roughly a third of what you're paying for. How Bad Is 1000 mAh? Let Me Put It in Perspective To really understand how disappointing these batteries are, compare them to what you get out of a standard quality alkaline AA — the kind you grab off the shelf at any store. A brand-name alkaline like a Duracell Coppertop or Energizer MAX typically delivers somewhere around 2500 to 3000 mAh depending on the load. These are disposable, single-use batteries that you throw away when they die, and they still deliver two and a half to three times the capacity of what Pujimax's rechargeable battery actually puts out. Read that again. A disposable alkaline AA — a battery you use once and toss — has significantly more usable capacity than these rechargeable lithium cells that Pujimax claims are superior. These are supposed to replace alkaline batteries. They can't even match them, let alone beat them. My Testing I used a DC electronic load to run proper discharge tests on multiple batteries from the pack. This isn't a cheap consumer gadget — it gives real, accurate measurements of actual battery output. I ran the tests several times across different batteries and got consistent results every time. ~1000 mAh across the board. Every battery I tested came in at roughly the same low number. The real-world impact of that low capacity is obvious. I originally bought these for an audio recorder I use regularly. A decent alkaline AA gives me days of intermittent recording without issue. These Pujimax batteries? A few hours and the recorder shuts off. I spent a while thinking something was wrong with my equipment before I started testing the batteries and realized the recorder was fine. The batteries just don't have enough in them. The Voltage Cliff Problem One more thing worth noting. With a regular alkaline battery, you can see it dying — the voltage gradually drops, devices start acting a little flaky, flashlights dim. You get some warning before the battery gives out entirely. These lithium cells hold a steady 1.5V output and then just cut off with zero warning. One minute your device works, the next minute it's dead. In something like an audio recorder, that means you can lose an entire recording in progress with no heads up at all. The 2000 Charge Cycle Claim — Where's the Proof? Pujimax also claims these batteries can be recharged up to 2000 times. That's a big number. That would make them extremely economical if it were true. But here's the thing — they provide absolutely no documentation, no test data, no third-party verification, nothing to support that claim. It's just a number printed on the packaging with nothing behind it. In my experience with rechargeable batteries — lithium, NiMH, or otherwise — you start seeing noticeable capacity degradation well before 2000 cycles. Realistically, I'd expect the decay to start becoming significant somewhere around 300 charge cycles, maybe a bit more if you're gentle with them. For these to actually hold up to 2000 charges with any meaningful capacity left would be remarkable, and remarkable claims require remarkable evidence. Pujimax provides none. When I asked about this, they wouldn't share any testing details. Same story as the capacity issue — "proprietary information." You're just supposed to take their word for it. I don't buy it, and neither should you. Contacted the Manufacturer — Got Nothing I reached out to Pujimax directly after running my tests. I laid out the numbers, explained the discrepancy between their advertised capacity and what I was actually measuring, and asked for an explanation. The response I got was clearly AI-generated. It didn't address any of my specific questions. It was generic, vague, and completely sidestepped the actual issues I raised. They didn't explain why the batteries were putting out about a third of their claimed capacity. They didn't offer any meaningful response about the 2000-cycle claim. Nothing. When I pushed and asked them to share their testing methodology — how they arrived at these numbers — they flat-out refused. Said their testing methods were "proprietary." So we're supposed to just trust a company that won't show its work and whose product demonstrably fails to meet its own claims. That's not how this works. The Verdict I understand that real-world capacity can differ from rated capacity. That's normal. What's not normal is a 65% shortfall between what's advertised and what's delivered. That's not manufacturing variance — that's misleading advertising. The choice to use mWh instead of the industry-standard mAh feels deliberately designed to confuse buyers who aren't going to do the math. And even after you convert and see the real claim, the batteries still don't hit that number. Then the 2000-cycle claim is just thrown out there with nothing to support it, and when you ask for proof, you get told it's proprietary and you can't see it. There are plenty of honest rechargeable AA batteries on the market from companies that stand behind their specs. This isn't one of them. I'll be updating this review with photos of my test results on the electronic load so you can see the actual numbers. The screenshots will show exactly what these batteries deliver — and it's not pretty. Would not buy again. Save your money and buy real batteries from a company that doesn't need to lie about what they're selling. Helpful? | Report this review

My Orbit 24634 B-hyve XD 4-Port Smart Hose Watering Timer was burning through the Chicnod 3300 mWh Li-ion USB-C rechargeable AA batteries in under a month and we were going on a two-month long trip. So, I bought these 4255 mWh AA batteries hoping that they'd last longer. They have and much longer: it's been 3 months now and they are still powering the watering system. I've very pleased with their performance. I ended up buying the 1512 mWh AAA model too: they're performing well too!

must have for everyone where else can you save 12,900 and that's no joke. Price out a dozen good alkaline batteries multiplied by 1500 which stands for the number of times these will charge. It's not a perfect world out there there are exceptions and reasons to not believe in these batteries for Life between charges etc however you'd have to be crazy to blow $12,000 on anything that has a copper top or a bunny.
