HP Laptop Battery Super Blog Here

The battery inside the moment any part of the solid material discharged by the batteries were pushed up more than 25cm distance, called the explosion. Determine if the Laptop battery explosion, using the following experimental conditions: The network covers an experimental battery, the battery life in the middle, away from the net on each side of the hood 25cm. Net density of 6-7 roots / cm, network cable with a diameter of 0.25 mm aluminum soft, if the experiment without solid part through the network mask to prove that the battery did not explode. Cause of the blast cells in general is:  

1, safety valves for unreasonable to fail to ensure safety.

2, charging the battery internal pressure are too high.

3, the battery has problems, such as N / P unreasonable, do not hear a battery will explode on the battery lead to fear. Indeed, as long as you use products (including batteries and chargers) is a qualified product, these problems would not exist.

Eligible products are backed by a rigorous control of the factory, and batteries and chargers have a charge and discharge protection device inside, even if the Dell Inspiron 6000 battery or charger, including a loss of protection performance, another also can also protect your battery will not overload, a phenomenon also responsible explosion does not occur. Even if the battery charger and protective devices are ineffective, if you find that the battery is very hot, stop charging and sent to the professional inspection will prevent this from happening.

User discussion about the cause of the battery exploding finish:

A saying:

1 may seal your well, intense chemical reactions. There is no gas to escape unharmed, he could skip the

2, burrs and dust caused by the micro-short circuits

3, is not the shipper problem?

4 is not equipped with anti-overcurrent (short circuit) using PTC

5, it should be the process of cell production does not control well, leading to swelling caused by perception and shorts.

6, batteries and chargers poor contact, resulting in excessive load-loader discharge protection within sampling (data) abnormal. Personal guess exposure is the main cause of the explosion!

7, the temperature must be considered when you’re likely to receive the hp Pavilion dv8000 battery temperature, especially in places like India, the battery and heat dissipation between the negative cable to the battery charger or the charger to heat the battery if the internal fault is likely to lead to internal short-circuit has evolved into the fire explosion, if the charger is not good at high temperatures may also lead to failure overload protection (provided that Internal battery protection against overload protection circuit is also null and void), is not strange if an explosion?

8, it may protect the board as tension problems.

In another way:

1, in fact, the cause of battery explosion, no analysis of several companies to emerge, most batteries factory did not make sense to get together and their online customers with reasons were acceptable.

2, can not find a better reason, remember to write the report must Yao insisted the explosion was an accident in the upper right is the correct path!

3, if there is an explosion in the discussion here can clear, I am afraid that nobody can make the battery a. Lithium is now the largest defect? Bang – trouble!

4, the capacity of lithium batteries is not too big to prevent the explosion turned into an offensive weapon!!

Battery Repair is the instrument of lead-acid battery repair battery repair. This imbalance can lead to battery acid, dehydration, sulphate, softening, shedding an open circuit, short circuit and cause other acid battery acid, the proportion of abnormal failure repair and re-distribution group to achieve the goal of re-use batteries.

Some form of battery failure and repair methods

1. Asymmetric

Most lead acid batteries are not used alone, but together with the multi-block, such as: “the batteries of electric vehicles are usually three or four together,” with a group of cells appear in one or two back, and can lead to many other’s can not use normally, is called an imbalance.

Repair Methods: identify the capacity, voltage, self-discharge, the battery internal resistance of batteries was used together.

2. Dehydration

In the process of battery charging, electrolysis of water, producing oxygen and hydrogen to make water into hydrogen and oxygen in the form of loss, and also known as condensate. Water in the system of electrochemical cells, play an important role in reducing the water will reduce the activity of ions involved in reactions to reduce the contact surface of lead sulfate and lead to increased resistance of the internal apple PowerBook G4 12 inch battery, the polarization intensified, ultimately leading to decline in battery capacity.

Repair Methods: The forced the battery cover at the top. Some of the battery cover is a glue ABS, a number of cells is connected by a loop. Many skateboard. Note that forced open the lid when not to damage the lid. So you can see 6 Cape exhaust valve rubber. Open the rubber exposed escape through the chimney can be seen inside the battery. Some basic exhaust valve rotary drum is open, you can not open the exhaust valve and rotation of the exhaust valves open rubber base. Some cells there is elastic around the filler cap. Open the lid, bright flashlight to see if there are dry holes in the phenomenon, whether the battery is dehydration. The plate of the battery is wrapped in a glass of white, cotton fiber, the normal situation should be moist. The inhalation of distilled water with the pipette of the fireplace in the cell. To add a set of good water blocking material covered ventilation breathable to prevent dust from falling into the chimney. Best in the medical use of secondary distilled water. Recovery of the principle of not more rather than less. You can not add more acid, causing a decrease in toshiba PA3465U-1BRS battery capacity will be insufficient. No experience, can master 5mL per hole. Is best viewed Canada, moist, shiny and watery. Just wet, shiny, more and watery too.

Special Note: recovery tool for the use of glass, plastic straws. Recommend the use of medical syringes, disposable, easy to use and convenient measure. Recovery tools do not use metal utensils, syringes, needles must be removed from metal, attached to a plastic tube for later use.

3. Sulfate

The discharge of the battery, the cathode has produced in the lead sulfate cathode, anodic oxidation of oxygen due to the very presence of sulfuric acid is extremely easy for the loading of lead dioxide, lead, while the cathode is different, except in long-term loss of power, often excessive discharge, requiring long-term unless there are other factors will be gradually formed on the surface layer of negative density hard layer of lead sulfate, not only in itself a significant decrease in solubility, it is difficult to participate in the response, while blocking the active electrolyte contacts and deep canal, causing the hp Pavilion dv8000 battery capacity will decrease.

Repair Methods: Pulse sulfide battery repair instrument repair, using high voltage (30V-50V) Pulse (8330HZ) small current (nominal capacity of the battery 1% -2%) of the way with 10 — 20 hours of time In addition to changing the battery in a hard lead sulfate crystals.

4. Plate softening

Plate is a multi-gap material, there area than the plate itself, the more surface area, the battery charge-discharge cycle repeated, with the board very alternative materials processing different rates will gradually plate space decline in performance over appearance, he plate is positive when the surface of a solid from the beginning a gradual change until it becomes very soft, then decreased due to surface would result in a decrease in battery capacity. High-current charge-discharge, excessive discharge would accelerate the softening of the plate.

Repair Methods: 10.5V Dell Latitude D830 battery discharge only after deep discharge 1-5 hours with the light bulb. Then use the device activation, activation of repair.

5. Grid corrosion

Skeleton of the battery grid alloy of lead, although there is strong resistance to corrosion, but the long-term immersion in an acid electrolyte, which is still cause corrosion of metals occurred in so that the grid crack or fracture occurs, leading to capacity decline.

6. Short

Initially, the diaphragm must be positive and negative plate (plate) separated, but if there are slag welding penetration or dendrites, then the Laptop battery positive and negative plate connected to form a short circuit, a serious short – circuit could cause the voltage becomes zero only if it leads to positive and negative resistance associated with the material itself is great, as the dendrites, it will not immediately single cell voltage becomes zero, but between autonomy faster discharge, commonly called “soft short-circuit.

7. Open

Occurs on the bus pole soldering and welding and soldering of the terminal event is usually not completely open circuit, but rather attached to cold welding, when the cold solder joint Department will have a strong resistance, causing decrease in IBM ThinkPad R40 battery capacity. The battery in May to provide a normal startup of all material respects, in use for some time after the cold welding phenomenon material, it is usually due to welding is not a good weld, there are cracks on the use of the process, this region has a first edge corrosion, resulting in a faster rate of fracture increased.

Repair Methods: 100A detect the battery voltage is 0V to open, using a measurement methodology to measure the open circuit where a good weld.
