Kratax Upgraded Rechargeable AA Lithium Batteries 2 Pack 1.5V High Capacity 3500mWh Li-ion AA Battery, 1600 Cycles, Precharged, Constant Voltage Output, Fast Charge (Charger not Included)
 
Product Features
  

         
High Capacity: 3500mWh Kratax 1.5V AA rechargeable battery, about 2H charging time, saving about half the time than the traditional Ni-MH rechargeable battery. Our AA lithium batteries has constant voltage output, the traditional battery products cant do that, and the voltage drops rapidly as the power decreases during use. (Not available on the camera flash) NOTE: This battery is a new generation of constant voltage output 1.5V rechargeable Li-ion battery, so the traditional universal charge
         
High Quality: Our AA rechargeable battery with a high-power cell with fully intelligent control IC chip, making it more reliable to use. The cycle time is more than 1600 times, one lithium battery is equivalent to 1600 disposable batteries.(Upgraded battery - up to 3A current, better application in high current devices such as Blink.)
         
Multi-Protection: There are four protections for this AA battery, with intelligent control of the entire charging process, built-in protection device to prevent Overcharge, Overvoltage, Overcurrent, Over discharge, the charger has reverse charge protection can protect the battery and charger very good. Our batteries and chargers have passed ROHS, CE, CQC, PSE, etc. certification.
         
More Durable: The most prominent feature of our AA lithium battery is 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.
         
Environmental: Low-carbon, it does not contain any toxic and harmful heavy metal elements and substances, such as lead, mercury, and cadmium. Nickel-plated steel shell material, anti-rust and anti-corrosion, long-lasting and durable.
         
NOTE: This link does NOT include a charger, but a special charger is required! This battery is a new generation 1.5V constant voltage output rechargeable lithium-ion battery and requires a charger that only works with this type of battery. Traditional universal chargers (for NiMH and Li-ion batteries) or chargers that can be used for 3V-3.7V Li-ion batteries are not suitable.
