What is the difference between the 38 and 38 2 batteries?

The differences between Chaowei lithium battery and Chaowei battery (battery) are as follows:

1. The nature of the concept is different.

Lithium battery: It is a type of battery that uses lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution. It mainly relies on lithium ions to move between the positive and negative electrodes to work.

During charging and discharging, Li+ is re-embedded and de-intercalated between the two electrodes; During charging, Li+ is de-embedded from the positive electrode, and the negative electrode is embedded in the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state. The opposite is true when discharging.

Due to the very active chemical characteristics of lithium batteries, the processing, storage and use of lithium metal have very high environmental requirements.

Battery: The battery is also called the secondary battery. It is a device that directly converts chemical energy into electrical energy, and is a battery designed according to rechargeability, which is recharged through a reversible chemical reaction, usually referring to lead-acid batteries.

After discharge, the internal active material can be regenerated by charging - storing electrical energy as chemical energy; When an electric discharge is required, the chemical energy is converted into electrical energy again. A battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.

2. The safety performance is different.

Lithium battery: lithium battery comes from the stability and reliable safety design of cathode materials, lithium iron phosphate battery has been strictly tested for safety, even in a violent collision will not produce **, lithium iron phosphate has high thermal stability, low electrolyte oxidation capacity, so high safety.

Battery: Lead-acid battery will produce ** under a strong collision, which poses a threat to the life safety of consumers.

38 is an ordinary battery, and, deliberately added a decimal point, is to attract everyone's attention, to distinguish it from ordinary batteries, which has been improved batteries, using new processes, technologies and so on.

These two batteries are actually the same, the main difference is that their production batches are not the same.

It should be between 80 yuan and 110 yuan, which is relatively normal and within a reasonable range.

OK. The charger limits the voltage to meet the full voltage of the battery, and the charging current is appropriate.

72V38AH battery, full left and right, charging current, rate current, charging time 5 10 hours, suitable.

72V5A charger, if it is nominal 72V, full 87V, current 5A, can be suitable.

20ah charger, the current is generally 3A, it can also be used, it is fully charged in about 13 hours, the charging time is too long, and the time of occupation affects the use.

The 72V5A can charge the 72V38A battery, which is fully charged in about 8 hours. However, it is best not to charge the 20A40A charger, because the charging current is 10% of the battery capacity, which can protect the battery to the greatest extent, just like a meal. Excessive charging current will accelerate the aging of the battery and it is still a virtual battery, so it is not recommended to try it.

The difference between Jinchaowei and Chaowei black gold battery lies in the difference in manufacturing materials, application fields, and positive and negative electrodes:

1. Plate-making materials.

rights are different. Jinchaowei battery: Jinchaowei battery is made of nickel-metal hydride, and the battery is mainly composed of a positive electrode, a negative electrode, a separator and an electrolyte. The electrolyte is mainly liquid, and the main component is potassium hydroxide (KOH).

Chaowei Black Gold Battery: Chaowei Black Gold Battery is made of alkaline zinc-manganese, and potassium hydroxide is used as the electrolyte.

2. Different application fields.

Jinchaowei battery: Jinchaowei battery is suitable for small current discharge, which can be used for calculators, remote controls, quartz clocks, landlines, etc.

Chaowei Black Gold Battery: Chaowei Black Gold Battery is suitable for high-current continuous discharge, and can be used for battery cars, electric vehicles, car backup batteries, etc.

3. The difference between positive and negative poles.

Jinchaowei battery: The positive electrode of Jinchaowei battery is nickel electrode (Ni(OH)2), and the negative electrode is generally metal hydride (MH).

Chaowei black gold battery: Chaowei black gold battery uses manganese dioxide as the positive electrode and zinc as the negative electrode.

Jinchaowei is the high-end brand of Chaowei Group.

Fields of application. Scooters, e-bikes, lightweight.

Specialized electric vehicles, electric motorcycles.

Pallet trucks, electric tricycles, etc.

Advantage 1: Ultra-long mileage: 10% increase in cruising range and short cruising range; Technological breakthrough: new process and new formula, high utilization rate of active substances, full weight;

2. Extremely fast start: withstand high-current discharge, and increase the power by 10%; Technical breakthrough: patented direct casting welding technology reduces internal resistance and improves heat dissipation;

3. Cadmium-free formula: green and environmentally friendly, healthy and worry-free; Technological breakthrough: invention patent for colloidal electrolyte, improving sulfuric acid stratification and lead ion dissolution;

4. Ultra-high cold resistance: -25 ultra-low temperature normal operation; Technological breakthrough: improve the anode process, and the low-temperature performance is significantly improved.

Black and gold superpower. Chaowei Black Gold Battery is the industry's first cutting-edge technology product that uses new nano-material graphene in lead-acid batteries, and is a model of high-energy batteries in the industry.

Fields of application. Electric moped batteries are widely used in special batteries for electric two-wheelers and tricycles.

Advantage 1: Chaowei Black Gold effectively targets user pain points such as battery life, service life, cold resistance, and load, and achieves the peak of battery energy with the highest capacity, lowest temperature performance, highest output power, and most power, bringing consumers a more comfortable and safe high-quality riding experience.

2. The upgraded version of Chaowei Black Gold, on the basis of the first generation of Chaowei Black Gold, fully realizes the technical upgrade, further improves the core technology of graphene alloy, and uses the unique "electrostatic column" structure, and the internal resistance of the battery connection is reduced by 52%.

Make the product performance more stable and have a longer service life.

These two batteries are generally one durable and generally one is not durable. I feel that Jin Chaowei and Chaowei black gold battery Chaowei's Jin Chaowei are compared, right?

They are all lead-acid power batteries, and Jin Chaowei is an upgraded version with a longer battery life.
