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.

🛠️ FAQ for DNK-LTB2S1PC18C25P2 7.4V 2500mAh Li-ion Battery

This configuration provides a stable and compact power source for mid-voltage applications.

Q2: What are the typical applications for a 7.4V 2500mAh battery pack?

A: This voltage and capacity range is highly versatile. Common applications include:

• Medical Devices: Portable oximeters and handheld infusion pumps.

• Industrial Equipment: Barcode scanners, rugged PDAs, and portable thermal printers.

• Consumer Tech: High-power Bluetooth speakers and walkie-talkies.

• Heated Gear: Heated vests, jackets, and gloves.

Q3: What type of BMS is integrated into the DNK-LTB2S1PC18C25P2?

A: Every DNK-LTB2S1PC18C25P2 pack is equipped with a custom 2S Li-ion Battery Management System (BMS). This circuit provides essential protection against over-charge, over-discharge, over-current, and short circuits. We can also customize the BMS with specific discharge current limits (e.g., 5A or 10A) based on your device’s peak power needs.

Q4: Can I customize the dimensions and connectors for this 7.4V battery?

A: Yes. While the standard size is approximately 18 * 36 * 65 mm, we can adjust the cell layout (e.g., side-by-side or stacked) to fit your internal compartment. We also offer various connector options such as JST, Molex, Hirose, or XT30/60, and can customize the wire length and gauge (AWG).
