These are the principles that guided the Compaq to reach the tips to help you optimize the performance of the battery in your Compaq laptop.

To maximize your Compaq laptop battery, as recommended by Compaq, you must:

1. Properly Break In Your New Battery

New batteries are not yet fully charged when sold. They must be recycled or put up first to get its optimum capacity. Charging and discharging of the presario cq60 battery for 4 or 5 times is enough to condition it.

2. Avoid the memory effect

The memory effect can be avoided by charging and discharging the Compaq Presario M2000 battery completely once or twice a month.

3. Clean your battery always

Dirt on the Presario V2000 battery contacts can reduce the performance of the battery in your Compaq laptop. Clean it with alcohol and cotton can give the impression and work like new.

4. Regularly exercise your battery

This method is recommended for those using the AC adapter as 60wh apple A1184 Charger for a longer period. It is advisable to use your Compaq NX7010 battery at least once in two weeks apart. Batteries lose their charge when stored for a long time and you need to break your battery when it happens.

Learn The Working Of The Lead Acid Battery In Depth In Simple Way

The lead acid battery consists of Sponge Lead, Lead Peroxide and Dilute Sulphuric Acid.

It contains plates with tiny square blocks. Lead peroxide is used for positive plates, whereas Sponge lead resembles negative plates. Both the plates are dipped in dilute sulphuric acid, and thereby the load is connected externally.

The electrolyte i.e. sulphuric acid contains charged ions of hydrogen (positive charged) and sulphate (negative charged). When the load is started whether it is headlight or starter, the negative ions contained in sulphate moves towards negative plates and the remaining ions form lead sulphate after combining with plate’s active material.

The strength of the electrolyte is reduced as a result of the process, and thereby an electrical insulation is created on the plate containing sulphate. The electrons flow from the negative terminal of the battery via electrical device to the positive terminal of the battery to complete the circuit. The positive electrons are accepted by the positive plates. In this process, two forms of liquid are formed.

  • Water – When hydrogen ions come in contact with oxygen contained in the lead oxide.
  • Lead sulphate – When sulphuric acid comes in contact with the lead.

The entire process creates the current flow by the movement of ions around the electrolyte, thereby producing electricity. At one point, the cells get discharged reducing the quantity of ions in the electrolyte and reduce the current flow. Low voltage and current flow makes it insufficient to start the vehicle.


The charging-discharging process continues as the battery is used. However, if the battery is kept without using for long, it gets self-discharged. Generally, the self-discharge rate is 1% per day. The self-discharge is affected the by temperature. For instance, with high temperature the rate increases and vice versa.

Charging process:

Electricity is not stored in the battery, and it is the chemical energy that is stored. The charging process reverses the electromechanical reaction and electricity is converted to chemical energy.

In the charging process, the negative ions are created at the negative plates thereby forcing the positive ions to get attracted towards it. The entire process of flow of electrons is reversed making the batteries fully charged.

Battery Life:

The battery life depends on many things and drastically reduces its performance or completely deplete. The following are the few main causes that reduce battery life.

  • The battery is kept in partially discharged state.
  • The battery is often deeply discharged making it less effective for chemical reaction.
  • If you keep the battery for charging for longer duration, the battery becomes unusable. When the rate of charging is more than the natural absorption rate, it will break down or boil the electrolyte.
  • If the battery is undercharged, the voltage will be sufficient for the operation, but will be insufficient if the battery is fully depleted.

Battery main elements impact on human health

Cadmium is an element that human not need, the body cadmium is uptaking from the external environment and then accumulation through the respiratory tract and the digestive tract after birth. The clinical manifestations of chronic poisoning is emphysema, bone changes and anemia.Japan found that some regions have the occurrence of pain patients due to long-term consumption the contaminated, high cadmium content rice and water.The main lesion is osteomalacia, The pain began lower extremity,and then throughout the body until the bedridden.

Chromate dust and chromic acid mist can cause nasal septum, part of the long-term contact patients’ symptoms include headache, weight loss, digestive disorders and gastrointestinal ulcers, mild renal injury.Carcinogenic chromium is increasingly attracting attention,ferrochrome smelting workers lung disease rate higher than that of other occupations.

Nickel usually from dietary intake, are considered to be induced lung cancer and nasal sinus cancer.Abroad have reported that nickel-induced lung cancer incidence have worked an average of 27 years.Nickel poisoning mainly caused respiratory damage,severe cases will be vague or unconscious mind,concurrent myocardial damage

Mercury is fat soluble. Through the blood-brain barrier into the central nervous system. Mercury is found in various tissues and organs, mainly in the liver, enters the body after 2 weeks, 85% – 90% of the mercury deposited in the kidneys, the main symptoms of chronic mercury poisoning is easily excited disease, tremor, stomatitis. Symptoms of mild poisoning is neurasthenic syndrome, autonomic dysfunction, and the impatience, irritability, crying, etc.when severe poisoning occurs the obvious personality changes, affective disorder, mental deterioration.

Intake of lead, mainly through food, drink and atmosphere.U.S. study suggests that the increase in human blood lead concentrations, lead to a corresponding increase in the degree of negative impact on health.Because lead can not easily be excreted, so it affects the kidneys, liver, nervous system and blood-forming organs, increasing blood pressure (increase the risk of heart attack in the middle-aged), renal function and interference with reproductive function, and irreversible brain damage. High blood lead levels can cause behavioral problems of children, low IQ and concentration difficulties

Manganese is an essential trace element the human body, but excessive absorption can lead to poisoning. Manganese can enter through the respiratory tract,also can be entered by the digestive tract. Liver is the main accumulation organ manganese, excessive exposure manganese accumulation in the central nervous system, which discharges slower than other organs
