4PCS 3000mAh Rechargeable Battery A Size 3.7Volt Li-ion & AA/AAA

Description: Excellent 3000 MAH 3.7V rechargeable lithium battery ideal for all those devices that use this type of battery, for example LED flashlights. Good durability, in fact it lasts longer than normal alkaline batteries. Pack of 4 Batteries 100% compatibility with the products for w hich its use is required. Compatible with all commonly used chargers, but we still recommend the use of reliable chargers to prevent damage to them. Specifications: Color boxed Protection function: over-voltage protection, overcharge protection, over-current protection, over-temperature protection, short-circuit protection, reverse connection protection, over-discharge protection Application range: lithium battery charging Input parameters: DC5V 1-2A conventional USB power supply Output parameters: DC4.2 1000mA Rated power: 2-5W Indicator status: red light during charging, green light when fully charged Compatible battery models: 10400, 14500, 16340, 16650, 14650, 18350, 18500, AA,AAA Features: 4 slot independent charging, non-interference, compatible with a variety of specifications rechargeable lithium batteries. Two-color charging indicator, red light when charging, green light when fully charged, connected to the power supply, do not put the battery, the green light is always on. Charging cut-off voltage is 4.23V full charge automatically stop, will not overcharge. Note: The maximum charging voltage of the lithium battery is 4.2 volts. Advantage: 1. Long life The lithium battery has a long life. The cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. 2. High safety performance The  lithium battery has high safety performance. In order to prevent the battery from short-circuiting, the positive and negative electrodes of the lithium battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protection board can be installed to avoid overcharge and overdischarge of the battery, which can also extend the service life of the battery. 3. High voltage. The voltage of lithium battery is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries. 4. No memory effect. It is not necessary to empty the remaining power before charging, which is convenient to use. 5. Small internal resistance: The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries, and the internal resistance of polymer batteries can even be below 35mΩ, which greatly reduces the self-consumption of the battery and prolongs the standby time of the mobile phone. , It can fully reach the level of conformity with international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace Ni-MH batteries. 6. It can be combined in series or parallel to form a lithium battery pack 7. Wide range of use: Laptops, walkie-talkies, portable DVDs, instrumentation, audio equipment, model airplanes, toys, camcorders, digital cameras and other electronic equipment.
