1.Don’t disassemble or modify the battery
DNK battery pack is packaged by Aluminum laminated plastic film which is easy to be damaged by sharp edge such as pin, needle, edge of devices like nickel tabs, etc. If they have serious damage, electrolyte leakage, short-circuit between positive and negative tabs, etc. It would cause the generation, smoke, rupture, or flaming with mishandling.
2.Don’t incinerate or heat the battery pack
Don’t use or leave battery nearby fire, stove or heated place (more than 130℃). These occur the melting of insulator, damage of safety function, or ignition on electrolyte. In case that separator made of polymer is melted by high temperature, the internal short-circuit occurs in individual cells and then it would cause the generating, smoke, rupture or flaming.
3.Don’t use any damage battery pack
Don’t use the battery that are dented or bent on their edge part. DNK batteries are possible to be damaged by strong mechanical shock and it would cause wire break, short-circuit inside the cell, leakage of electrolyte, etc.
4.Don’t drive a nail into a battery pack, strike it by hammer, or tread it.
As the battery might be broken or deformed and then it will be short-circuited, it would cause the generating, smoke, rupture or flaming.
5.Don’t give battery pack impact or fling it
If the battery is broken, the battery will be charged at abnormal voltage or current and abnormal chemical reaction will occur. It may cause the generating, smoke, rupture or flaming.
6.Don’t make the direct ultrasonic wave power to the battery or soldering near the battery
It may cause serious damage to the batteries. Soldering near the battery may cause damage of the components, such as separator and insulator, are melted by heat, it would cause the gas generating, smoke, rupture or flaming.
7.Don’t use battery nearby the high temperature place or under the blazing sun.
DNK batteries have possibility to be degraded its performance such as capacity, thickness increase, impendence, etc. The battery will be charged at the abnormal chemical reaction occurs in the high temperature place. The thickness change may lead to stressing on battery case/ device, wiring or cell which may have possibility to lead to damage performance.
8.Don’t use the unspecified charger.
If the battery is charged with unspecified condition, there are causes that it will be overcharged or the abnormal chemical reaction will occur in cells. It causes the gas generating, smoke, rupture or flaming.
9.Don’t reverse polarity (and terminals)
On charging, the battery is reversed-charged and abnormal chemical reaction occurs. There may be case that unexpected large current flows on discharging. There causes the generating, smoke, rupture or flaming.
10.Don’t reverse-charge or reverse-connect
The battery has polarity. In case the battery is not connected with charger or equipment smoothly do not force them to connect and do check polarity of battery. If the battery is connected to opposite polarity with charger. It will be reverse-charged and abnormal chemical reaction will occur. It would cause the generating, swelling, smoke, rupture or flaming.
11.Don’t connect battery to the plug socket or car-cigarette-plug
Added high voltage to the battery, the excessive current will flow in it and then it may cause the generating, swelling, smoke, rupture or flaming.
12.Don’t use battery for another equipment
If the battery is used for unspecified equipment, it will deteriorate its performance and cycle-life.
13.Don’t touch a leaked battery directly
In case the leaked electrolyte gets into eyes, wash them with fresh water as soon as possible without rubbingeyes. And then, see a doctor immediately. If leave damaged eyes undone, it will cause eye-trouble.
14.Keep the battery away from babies
Keep the little battery out of the reach of babies in order to avoid troubles by swallowing. In case of swallowing the battery, see a doctor immediately.
15.Don’t get into a microwave or a high pressure container
Because of sudden heat or damage of sealing condition of battery, it may cause the generating, smoke, rupture or flaming.
16.Don’t use a leaked battery nearby fire
If the liquid leaks from the battery (or the battery gives out bad smell), let the battery leave from flammable objects immediately. Unless do that, the electrolyte leaked from battery may catch fire and it would cause the smoke, flaming or rupture of it.
17.Don’t use an abnormal battery, such as leakage, swelling, deformation, etc.
In case the battery has bad smell, it generates, its color change or it is warped in using (includes charging and storage), let it take out from equipment or charger and do not use it. If an abnormal battery is used, it may generate bad performance or damage the device or pack.
Q: What is the estimated cycle life of the 11.1V 2.6Ah battery pack?
A: Under standard testing conditions (0.2 °C discharge, 25°C), our battery typically maintains over 80% of its original capacity after 500 full charge/discharge cycles. With proper maintenance, the service life can extend to 2-3 years.
Q: What certifications does this battery pack carry?
A: Our cells are compliant with UN38.3, IEC62133, and CE standards. If your project requires specific certifications like UL2054, PSE, or BIS, we can provide testing services and documentation support for the finalized pack design.
Q: Can this battery be used in cold environments?
A: Yes, the battery can operate between -20°C and +60°C. However, please note that discharge capacity decreases in cold weather. At -10°C, you may expect about 60-70% of the rated capacity. For extreme cold, please consult us for specialized Low-Temperature cell options.
Q: Does it support series or parallel connection to increase voltage/capacity?
A: We strongly recommend against connecting standard finished packs in series or parallel by yourself. This can damage the internal BMS. If you need a 22.2V or 7Ah solution, please let us know, and we will build a dedicated pack with a synchronized BMS for you.
Q: What are the lead wires and connector options?
A: Our standard pack comes with 100mm 20AWG or 22AWG wires. We offer a wide range of connectors including JST-SYP, Molex, XT30/XT60, and DC 5.5mm plugs. Custom wire lengths and specialized connectors are available upon request.
Q: Can I integrate an NTC thermistor for temperature monitoring?
A: Yes. We can include a 10kΩ or 100kΩ NTC inside the pack, leading out a third wire (usually yellow or white). This allows your device's controller or charger to monitor the battery temperature in real-time for enhanced safety.
