FAQ
1. Are you factory?
A: Yes, we are factory at Shenzhen China. Welcome to visit our company at any time when you come to China.
2. Do you have current sample in stock?
A: Usually we don't have, because different customers have
different requests, even the voltage and capacity are the same,
other parameters maybe different. But we could finish your sample
quickly once order confirmed.
3. What's the delivery time for mass production?
A: Usually 15-25days, it depends on the quantity, material, battery
cell model and so on, we suggest to check delivery time case by
case.
4. OEM&ODM are available?
A: Sure, OEM&ODM are welcome and Logo can be customized too.
5. What is the normal lifetime about battery?
A: More than 800 times for lithium ion battery; more than 2,000
times for LiFePO4 lithium battery.
6. What is your MOQ?
A: 1PCS sample order can be acceptable for testing.
7. How to maintain the battery?
A: The battery should be stored in clean, dry, ventilated, dark
environment
when not using,keep it after full charge, recharge it every 3
months or 6 months.
8. Why choose HANDPACK Battery?
A: 1) A professional sales team which provide consultant service
and the most competitive battery solutions.
2) Wide-range battery products to satisfy different customer's
requirement.
3) Quick response, every inquiry will be replied within 24 hours.
4) Good after-sale service, long product warranty and continual

Attentions
(1) Do not immerse the battery in water, and keep the battery in a
cool dry surrounding if it stands by.
(2) Do not use or leave the battery at high temperature as fire or
heater. Otherwise, it can overheat or fire or its performance will
be degenerate and its service life will be decreased.
(3) Do not reverse the position and negative terminals.
(4) Do not connect the battery electrodes to an electrical outlet.
(5) Do not short circuit. Otherwise it will cause serious damage of
the battery.
(6) Do not transport or store the battery together with metal
objects such as hairpins, necklaces, etc.
(7) Do not use the battery in a location where static electricity
and magnetic field is great, otherwise, the safety devices may be
damaged, causing hidden trouble of safety.
(8) Please use special lithium charger.
(9) It should be noted that the cell would be possible to be at a
over-discharged state by its self-discharge characteristics in case
the cell is not used for long time. In order to prevent
over-discharging, the cell shall be charged periodically to
maintain about 13.2V(Recommended 3 months one
cycle).Over-discharging may causes loss of cell performance,
characteristics, or battery functions.
(10) Do not disassemble battery.
