After-sale Service
All of Borui battery cells in a pack are with very high
consistency.In a pack, each cell has its own sole electronic
code(ID number) for quality control after-sale. Assume one cell in
a pack is damaged in any reason after several years later, we could
provide a exactly same cell to the client to replace this damaged
one(same voltage, capacity, impedance,etc.), in order to make sure
all of the cells in this pack with very high consistency. Borui has
a strong system working for this.

FAQ:
1. How would the goods be shipped?
We ship via UPS,DHL ,FEDEX and sea transportation normally.
2. Can you print my picture or logo on the battery cover?
Yes, OEM is available,we can print your picture or logo on the
battery case, and you can offer your logo.
3. What's your warranty for battery?
Our battery the warranty time is 5 years .
4.Can I force-discharge lithium batteries?
When batteries are force-discharged with an external power source,
the voltage drops to under 0 volts (which is called voltage
reversal ) and internal gas is generated. This can lead to
swelling, heat generation, leakage, rupture or fire.
5.Can I use Lithium batteries mixing with other battery types?
If different types of batteries are used together, or new batteries
are used with old ones, the difference in characteristics of
voltage, capacity, etc., may cause over-discharge of the battery
which is exhausted first, leading to swelling, bursting or fire.
6.Where should lithium batteries be stored?
Lithium batteries should be stored in a cool, dry place that is not
exposed to direct sunlight and has minimal temperature variation.
Storage in areas subject to high temperature or humidity may cause
deterioration in battery quality and durability. To avoid short
circuiting batteries during storage, be sure that the positive and
negative terminals do not come into contact with each other.
7.What is a short circuit?
If the positive and negative terminals of a battery come into
contact with each other or with a conductive metallic object, this
can cause a short circuit, which generates heat. If cells or
batteries are stacked on top of each other or mixed, the resulting
short circuit can lead to heat generation, leakage, rupture, and
possibly fire.
