Kratax 8pack High-Capacity 3500mWh Rechargeable Lithium AA Batteries with 2H Quick Battery Charger Remind: The rechargeable lithium AA batteries do not support the CAMERA FLASH! Size: 50.5*14.6mm (Slightly longer than AA batteries without a protective plate)The Kratax long-lasting 1.5v rechargeable AA battery adopts the exhaust explosion-proof design, and the safety level is high.1600 times charge and discharge cycles. If it used on the remote control for TV, you may without changing battery for a few years. The energy is so powerful that you can’t imagine it.More economical, free of Lead and Mercury, rechargeable batteries can reduce the harm of regular batteries to the environment.Constant voltage output: Kratax 1.5v rechargeable AA battery provide an approximately equal and stable voltage to the device until it runs out of power. 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. Suitable for all kinds of high-power demand electrical device! Up to 3A current output which can be better applied to high current devices.Suitable for Xbox Controller, Blink camera, Electric Toys, Remote Controls, Smart home devices, Microphone, Electric shaver, Medical Devices etc. Household and Office Devices. Flashlight(The charging current of the flashlight is less than 2A to be used).(Not available on Camera Flash, Seiko R-Wave Mantel Clocks and AM Radio) Quick Battery Charger Charging Time: About 2 hoursInput: Type-C 5V 2AOutput: 500mA*4ChIndependent charging channelCharging Voltage: 5V 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. Constant voltage output 1.5V Lithium-ion battery is a new generation of battery, so this Kratax charger is only suitable for this new type of battery, not for the traditional 3V-3.7V Li-ion battery. Constant Voltage Output Longer life than normal Alkaline batteries and other rechargeable battery. 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. Cost-effective Capacity: 3500mWh / 2333mAh Charging time than the traditional Ni-MH rechargeable battery saving about half the time. 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. More Durable It is recommended to use Kratax battery and Kratax charger as a set, not to mix with other brands. QUESTIONS 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. Q: Why do lithium-ion batteries feel a little bigger than alkaline batteries? A: The size of our battery is 50.5mm*14.6mm*14.6mm (L*W*H), because the lithium-ion battery is equipped with a protective plate, it may be 0.1~0.2mm larger than the length and diameter of a few alkaline batteries, mainly depends on What product to compare with.
