LFP Battery Cell Tesson Technology

The LiFePO4 battery cell, similar to the battery cell, is a type of rechargeable lithium-ion battery. The name &#;&#; is a numerical code signifying its physical dimensions &#; a diameter of 26mm and a length of 70mm, with the &#;0&#; indicating its cylindrical shape.

Like other lithium-ion batteries, cells are utilized in a wide range of electronics due to their high energy density, which allows them to store substantial energy proportional to their size. This makes them particularly suitable for high-drain devices like power tools, electric vehicles, and various portable electronics.

Each LiFePO4 battery cell typically delivers a nominal voltage of 3.2 volts, a bit lower than the 3.7 volts seen in traditional lithium-ion cells. Nevertheless, they offer high capacity, ensuring long-lasting performance and considerable runtime between charges.

What sets LiFePO4 batteries apart is their impressive recharge cycle life and their inherent safety features. As rechargeable cells, they are an environmentally friendly option as they reduce the waste associated with single-use batteries.

Safety is a paramount consideration with cells. Their LiFePO4 chemistry adds an extra layer of safety, as it&#;s more stable and less prone to overheating compared to other types of lithium-ion batteries. While they still require protections from overcharging and short-circuiting, LiFePO4 cells are known for their stability and reliability.

Q1: What capacity do I need?

This will depend on how much power your device uses and how long you want it to run between charges. Capacity is usually measured in milliamp-hours (mAh) or watt-hours (Wh). Contact us to find a suitable solution.

Q2: What&#;s the difference between Lithium-ion and Lithium-polymer?

These are two types of rechargeable lithium batteries. Lithium-ion batteries usually come in a rigid metal case, while Lithium-polymer batteries are often encased in flexible pouches. They have different characteristics in terms of energy density, capacity, and safety.

Q3: Are all lithium batteries rechargeable?

No, there are also non-rechargeable (or &#;primary&#;) lithium batteries. Lithium-ion and Lithium-polymer are the most common types of rechargeable (or &#;secondary&#;) lithium batteries.

Q4: What is the C-rate?

The C-rate is a measure of the rate at which a battery is charged or discharged. For example, a 1C rate means the battery&#;s discharge current will discharge the entire battery in 1 hour.

Q5: What&#;s the life expectancy of a lithium-ion battery?

Lithium-ion batteries typically last for hundreds to about a thousand charge cycles. Their lifespan can be influenced by various factors including temperature, how they&#;re used, and how they&#;re charged.

-Cautions-

1.Don&#;t use or leave the battery under the blazing sun (or in heated car by sunshine)

The battery may smoke, heat or flame. And also, it might cause the deterioration of battery&#;s characteristics or cycle life.

2.Manual

Please read the manual before using the battery and let it keep after reading. And also, please read it necessary.

3.Charging Method

Please read the manual of specific charger about charging method.

4.First time use

When the battery has rust, bad smell or something abnormal at first-time-using, do not use the equipment and go to the shop which it

-Danger!!!-

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.

Xiaolu are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

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.
