Description

Multi-protection function: Built-in protection device to prevent Overcharge, Overvoltage, Overcurrent, Over Discharge, Reverse Charge and Short-circuit protection, can protect the battery and charger very good. Red Indicator --- Charging Green Indicator --- Full charged (The blue light at the positive pole of the battery is up when charging, and goes off when the battery is full) Red flashing --- Error ----The charger adopts a high-precision IC control system with battery identification and data reading capabilities. If other types of batteries are mistakenly charged, the charger will issue a flashing red light warning message. Stable outputs voltage from 100% to 0% electric capacity, 1.5V constant voltage output at 100mA discharge, providing constant voltage and best performance in high current and voltage device. Capacity: 3500mWh / 2333mAh This battery takes only about half the time to recharge of traditional NiMH rechargeable batteries. Low self-discharge, is about 0.03% per month, which is less than 1/100 of Ni-MH batteries. The weight is about 19g, is 20% lower than Ni-MH batteries. It is recommended to use Kratax battery and Kratax charger as a set, not to mix with other brands. Q: Which one has a longer working time, Kratax constant voltage rechargeable lithium battery or disposable battery? A: Disposable batteries have a longer working time, but our lithium-ion batteries can be charged and discharged repeatedly, with a longer overall use time and a higher cost-effectiveness. Disposable batteries can maintain good performance in the initial use due to their higher voltage. As the use time increases, the performance gradually decreases until the user replaces the battery. Our lithium battery has a constant voltage, which allows the device to maintain the optimal performance within the settings until the battery stops outputting, so the working time of a single lithium-ion battery will be reduced by about half compared to disposable batteries.

  • Long lasting durable batteries
Size: 8 AA batteries & Charger
I've now used these batteries for a year and have recharged them several dozen times. They work extremely well in my Schlage door locks, game cams and older Fenix LED flashlights. I will definitely repurchase these when needed.

  • Work better when used
Size: 8 AA batteries & Charger
I wrote a review on these before. To make story short, when I first purchased that brand, I was not impressed. Batteries did not hold charge very well. What I discovered after more prolonged use, is that these batteries hold charge better after multiple use discharge-recharge cycles. Work really well, easy to recharge. Real money savers. Thank you Kratax! Even with a metall circle falling of the bottom of one battery, it keep working :) ... show more

  • Convenient Money Saver
Size: 8 AA batteries & Charger
I used to buy regular batteries for devices like a portable AM/FM radio, remote controls, model house lights, and wireless intercoms. Replacing them frequently became expensive and inconvenient. These rechargeable AA batteries have been a great solution. I purchased my first set in July 2025 and added more later. They recharge easily, perform reliably, and have saved me multiple trips to the store. So far, they’ve held up well, and I expect them to last a long time. A practical and cost-effective upgrade. ... show more

  • Work well and hold a charge.
Size: 8 AA batteries & Charger
I use a set of these in a trail camera and they last a long time. They're picky about needing to be charged in the supplied charger, but I don't consider that an issue.

  • TERRIBLE BATTERIES
Size: 8 AA batteries & Charger
I bought these for my Blink patio camera, which does get a lot of use because it comes on every time an animal comes to my patio. I’ve bought several brands of rechargeable lithium batteries to compare them and try to figure out which works the best. These particular batteries worked ONE time! I put them on the charger and when the lights turned green, indicating they were fully charged and ready for use again, I put them in my Blink camera and they did not work. I put in another brand that I had and also had just charged and they worked beautifully and are STILL working after a week of almost constant use. I bought these because of all the great reviews. But I apparently got all duds because mine didn’t work but once. ... show more

  • No issues, 14 months still recharging
Size: 8 AA batteries & Charger
I have 5 Blink cameras. I have 20 batteries. I have ran these cameras through all four seasons. There has not been any issues. When I run the batteries down, especially on the high use cameras, I charge them up when I swap Before I go to swap out again, I top them off in the chargers. The reason I do it this way is because if a high use camera has drained the battery down to complete depletion, I don’t want it sitting at the low charge state, waiting until I need it again and then the charger may not charge it due to too low of voltage level. It could go into the danger zone of too low-voltage and never recharge again. I haven’t had this issue with these batteries, but I have with my power tool batteries and vape batteries. So back to the cameras, the batteries, (AA) work well. I haven’t used them in other devices, but I am planning on using them in a smart lock. They saved me a ton of money by not having to buy disposables. When the first camera reports battery failure, I replace all the cameras batteries. I wish the cameras report an actual battery life remaining, but I would say they last at least a month and a half if not longer depending on usage. They charge very fast with no issues. ... show more

  • These things are like fine wine. They just get better after 4 to 5 cycles.
Size: 12 AA batteries & Charger
The only negative is the life is only 1 1/2 weeks the first few cycles. At 6 cycles they're powering my Spartan Trail Cameras for 4 and 5 weeks. I own 24 of these per camera so I always have a hot set. A little expensive initially but you do the math. FYI, I've tried the solar panels. They are just another link that ends up being an issue. ... show more
