4. 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.

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.
