Q
Q:Can I take power bank on an airplane?

A

A：According to Civil Aviation regulation, as long as the rated power of your power bank no more than 100Wh, quantity no more than 2pcs, you can take on an airplane.
Q
Q: Can you ship lithium ion battery packs by Fedex?

A

A: Most FedEx Ship locations do not accept dangerous goods shipments, except for permitted IATA Section II lithium batteries. We can't arrange battery shipment by Fedex directly, but this doesn't means shipment can be a problem for us, with over 12 years experience, we have a lot of forwarders with rich experience, shipment is easy for us.
Q
Q: How to calculate the charging time for a lithium battery?

A

A: The charging time for a lithium battery is affected by capacity and charging current.Formula is :　Charging time= Battery capacity(C)/charging current(I)But actually charging time is longer than the theoretical value, because there's enenrgy loss during charging.Contact person: Ashlee PengEmail:poeae@liliangbattery.comwww.liliangbattery.com
Q
Q: What's inner voltage testing?

A

A: Lithium ion battery pack inner voltage testing standard is UL.Simulate the battery at the altitude of 15240m to see if it will leak liquid or puff.Progress: Charge the battery at 1C untill the voltage reaches 4.2V ,cut off current is 10mA, then put it into a low pressure box wtih 11.6Kpa air pressure and temperature of 20±3 centigrades for 6 hours, the battery won't explode, get on fire , leakage or crack.Contact person: Ashlee PengEmail:poeae@liliangbattery.comwww.liliangbattery.com
Q
Q: Will it affect the capacity if the 18650 battery cell is with PCM protection?

A

A: No , it won't affect the capacity when the 18650 battery cell is with PCM protection. LIthium ion battery short circuit protection time is about 300uS,just like connecting a big capacitance and being changed for one time.Contact person: Ashlee PengEmail:poeae@liliangbattery.comwww.liliangbattery.com
Q
Q：Is it possible to explode if we make a 18650 battery with PCM short circuit?

A

A: A 18650 battery won't explode when short circuit if there's a PCM inside. Because the PCM will cut off the power when short circuit.Contact person:Ashlee PengEmail:poeae@liliangbattery.comwww.liliangbattery.com
Q
Q: Is it good to charging mobile phones when it's on?

A

A: A lot of customers asked such question. And the answer is "no". Because when the mobile phone is on, it means it's discharging, and charging represents it's supplying power for the phone, so it's charging and discharging at the same time, which may lead to voltage chaos, and then the circuit board inside will get heating. It may also cause instant current backflow If ther's a phone call when it's charging, which may damage the components inside. As time passes, the mobile phone and the rechargeable battery inside will not work well anymore, or even can' work. Contact person: Ashlee PengEmail:poeae@liliangbattery.comwww.liliangbattery.com
Q
Q:What's the advantage of lithium battery?

A

A: 1.High energy density ratio; 2. High working voltage; 3. No memory effect; 4. Environmental; 5. Light weight; 6. Low self-discharge rateContact person: Ashlee PengEmail:poeae@liliangbattery.comwww.liliangbattery.com
Q
Q: What's "green battery" ?

A

A: New green battery means a high performance and environmental battery. Lithium ion battery, Ni-MH battery and mercury free Alkaline battery are green batteries.Contact person: Ashlee PengEmail:poeae@liliangbattery.comWebsite:www.liliangbattery.comTel:+86-13360681526
Q
Q: What's the self-discharge rate?

A

A: It means the electricity which can be discharged from the Li-ion battery under a certain condition.It also means the charge retention ability, the ability of keeping the electricity storaged into the battery under open circuit condition. It mainly effected by the battery manufacturer process, materials and the storage condition. And it's the main parameter to measure the battery peformance.

Q
Q: How to control the battery moisture inside during producing?

A

A: Do moistureproof processing;B: Shorten the producing time, decrease the exposure time of the lithium battery tab in the air;C: backing and dehumidifying job should be done correctly;D: Working under dry condition.Contact person: Ashlee PengEmail:poeae@liliangbattery.comWebsite:www.liliangbattery.comTel:+86-13360681526
Q
Q: What's the designed capacity of the battery?

A

A: It's the calculated capacity based on electric chemical theory according to the active material in inside of the battery.Contact person: Ashlee PengEmail:poeae@liliangbattery.comWebsite:www.liliangbattery.comTel:+86-13360681526
Q
Q: What's the battery capacity?

A

A: It means the power which could be discharged out from a battery under a certain condition.Contact person: Ashlee PengEmail:sales01@liliangbattery.comWebsite:www.liliangbattery.comTel:+86-13360681526
Q
Q:What's the average volage?

A

A: it's the average voltage of the lithium battery when it discharges power, from the begining till it ends.Contact person: Ashlee PengEmail:sales01@liliangbattery.comWebsite:www.liliangbattery.comTel:+86-13360681526
