Q：What is the difference between lithium batteries and other rechargeable batteries?A：First of all, this product belongs to the Lithium ion battery, namely lithium battery . Whereas the rechargeable battery refers to nickel-metal hydride or nickel-cadmium batteries, which are fundamentally different. Compared with NiMH or NiCd batteries, the lithium battery has such characteristics as high energy density, long cycle life, no memory effect, quick charging speed, ultra-low self-discharge, light weight and environment-friendly. In other word, the phone battery we use now is basically the lithium battery, which is well understood. The phone battery is also developed from nickel-cadmium and nickel hydrogen batteries. Lithium battery represents the best battery energy technology at present.Q：Is the product really the lithium battery? Is its voltage really 1.5V?A：Absolutely no doubt about that. This is a new technology that has obtained patent (Chinese patent number: ZL201110219892.0, ZL201310436748.1, ZL201310436714.2, ZL201320588983.6, ZL201320588986.X; US Application Number: 15024204; European Patent Application No. 14845187.5) . This product has gone through years of technical improvement and rigorous performance testing. It has achieved very satisfactory performance parameters. So users can be assured.Q：How long does it take to charge JUGEE batteries?A：It takes about 3.5 hours to fully charge AA AAA battery using charger JG-CUM54 JG-CUA52. Tips: Due to the special charging characteristics of lithium battery, when the charging time reaches half of the entire charge cycle, the battery has reached more than 85% of the full electric quantity. So in the case of emergencies, it just need half the charging time, thus saving your valuable time.Q：Why the product is marked of mWh rather than mAh?A：mWh represents milliwatt hour, on behalf of the battery capacity. It is labelled in accordance with the new labeling specifications of lithium-ion batteries. mWh = mAh * voltage.Q：What is the difference between lithium iron phosphate battery and universal polymer lithium battery?A：The differences lie in: 1) Voltage: the voltage of lithium iron phosphate battery is 3.2 V. When fully charged, its actual voltage is 3.6 V or so. Such a high voltage is beyond the limit voltage of the appliances using AA or AAA universal battery. So it is easy to damage the appliances (note: this is why the businessman has repeatedly remind users that the battery fully charged should be placed more than 1 hour until the voltage drop, then they can use); universal lithium battery uses intelligent voltage transformation technology, with the constant voltage output voltage of 1.5 V, to ensure the standard voltage of the appliances. (You can check the input voltage parameters on the labels of electrical appliances) Note: the use of this product is like the use of ordinary dry batteries, dont need to add another bit bucket! 2) Security: Strictly speaking, lithium iron phosphate battery cannot be considered as batteries, it is just a cell, without protection circuit; universal lithium battery uses multiple intelligence protection circuit preventing overcharge, over discharge, short circuit, overheating, very safe to use. This is also a reason why the cost of the product is higher. Note: lithium iron phosphate battery, because of no protection circuit, have been over discharged when many electrical equipment reach the lowest limit voltage. This is why businesses repeatedly remind users that: Do not charge the battery until it is completely discharged! 3) Capacity: generally, the highest capacity of lithium iron phosphate battery is 600mAh. Its nominal voltage is 3.2V, to be used with bit bucket. Take the electrical equipment using two AA batteries for example. Lithium iron phosphate battery: 600mAh × 3.2V × 1 + 0mWh × 1= 1920mWh; JUGEE JG5G3000 Li-Ion battery: 3000mWh(2000mAh × 1.5V) × 2 = 6000mWh, JUGEE JG7C1000 Li-Ion battery: 1000mWh(667mAh × 1.5V) × 1 = 2000mWh; it can be seen that the capacity of JUGEE lithium batteries is nearly three times that of lithium iron phosphate in the practical application.Q：Why do the JUGEE li-ion batteries require the manufacturers stock charger? (2-slot JGCUA52 4-slot JGCUM54)？A：The advantages of JUGEE chargers1. Compliant with MILBEP specifications.2. Independent charging control for each charging port.3. Thermal power control during the charging process.4. Prevents alkaline batteries and NiMH batteries from being incorrectly charged.5. Voltage should remain around 5V.6. User can freely load or unload the batteries during any charge. 7. There is no minimum load number or slot requirement. (batteries do not have to be charged in pairs.)Q：What is the concept of the product compared with the ordinary disposable batteries?A：The product uses polymer lithium cells, which can be recycled 500 to 1000 times. The full charged electricity once is equivalent to that of 2 to 5 batteries. It is no exaggeration to say that a universal lithium battery is equivalent to 1000 to 1500 alkaline batteries, 5000 to 6000 ordinary KK batteries. Thats economical and environment-friendly.Q：Is the battery safe?A：It is very safe, because there are multiple protection mechanism inside the battery. If the voltage conversion circuit is damaged, protection circuit will truncate the output, and the output voltage will be zero.
