Kratax 4 pack High-Capacity 3500mWh AA Rechargeable Lithium Batteries with 2H Quick Charger Remind: The rechargeable lithium 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 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.Free of Lead and Mercury, rechargeable batteries can reduce the waste of disposable batteries. 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! Controller, Toys, Remote Controls, Smart home devices, Microphone, Electric shaver, Household 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 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 full 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 / 2300mAh Charging time is about half that of NiMH rechargeable batteries. Low self-discharge rate of about 0.03% per month, about 1/100th of that of NiMH batteries, and weight of about 19g, about 20% lighter than NiMH batteries. More Durable It is recommended to use Kratax battery and Kratax charger as a set, not to mix with other brands. QUESTIONS Q: Can batteries be used for blink cameras? A: The battery is suitable for most people's blink cameras, but when the camera runs frequently (such as an object that is constantly moving), the current consumption is too large, it may affect the usage time. Q: Lithium-ion batteries and disposable batteries, which lasts longer in the flashlight? A: The disposable battery has a long working time, but the lithium-ion battery can be recycled, the overall use time is longer, and the cost performance is higher. The disposable battery can maintain high brightness due to the relatively high voltage during early operation. Then as the voltage decreases, the brightness will become lower and lower until the user replaces the battery. The Lithium-ion battery voltage is constant, so the flashlight can maintain the highest brightness in the setting until the battery stops outputting, so the working time of a single lithium-ion battery will be about half less than that of a disposable battery. Q: Why does it feel like a disposable battery discharges more power than a Li-ion battery? A: Because the disposable battery does not need to be charged, it can use up all the power. Lithium-ion batteries require a secondary charge of the battery, so some of the power needs to be retained to maintain the battery's activity, So it will feel like the disposable battery releases more power. 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.
