Lithium Batteries
Lithium battery types include lithium-manganese dioxide, lithium-sulfur dioxide, Hp laptop battery,and lithium-thionyl chloride. The anode is composed of lithium and the cathode is composed of manganese dioxide (or sulfur dioxide, or thionyl chloride). The electrolyte of the lithium-manganese dioxide battery is composed of an organic solvent (propylene carbonate and 1,2 dimethoxyethane) solution of lithium perchlorate. In the case of lithium-sulfur dioxide, the electrolyte is also an organic solvent (acetonitrile) solution with lithium bromide. Lithium-thionyl chloride batteries have a non-aqueous thionyl,Pavilion ZE2000(hp ze2000 battery), Presario M2000(compaq m2000 battery), Presario V2000(compaq v2000 battery), pavillion zx5000(hp zx5000 battery), chloride solution containing lithium aluminum chloride. Lithium-sulfur dioxide batteries contain pressurized sulfur dioxide gas and lithium-thionyl chloride batteries contain liquid thionyl chloride which vaporizes upon exposure to air, both of which are highly toxic.
Magnesium Batteries
Magnesium batteries have a magnesium anode, manganese dioxide cathode, and an electrolyte of an aqueous solution of magnesium bromide or magnesium perchlorate. These chemicals can emit highly toxic fumes when heated. If batteries show signs of leakage, proper eye and skin protection is recommended during handling.
Mercury Batteries
Mercury batteries have a zinc anode,Pavilion ZE2000(hp ze2000 battery), mercuric oxide cathode, and an electrolyte of an aqueous solution of potassium hydroxide or sodium hydroxide. The cell has a solid cathode of mercuric oxide and contains 20 to 50 percent mercury or mercuric oxide, by weight. The battery cell contains a caustic electrolyte and can have the same adverse health effects as alkaline batteries.
Nickel-Cadmium Batteries
Nickel-cadmium (ni-cad) batteries have a cadmium anode, nickel oxyhydroxide cathode, and an electrolyte of an aqueous solution of potassium hydroxide. The battery cells typically contain 13-15 percent cadmium and 20-30 percent nickel, by weight. The electrolyte is a caustic solution and is capable of causing the same health effects as alkaline batteries addressed above.
Silver Batteries

Silver batteries have a zinc anode, silver chloride cathode, and an electrolyte of an aqueous solution of lithium chloride or zinc chloride and zinc sulfate.Presario M2000(compaq m2000 battery), The electrolyte is a mild acid (20 to 30 percent by weight) and can cause serious chemical burns to the skin and/or eyes.
Thermal Batteries
Thermal batteries have a calcium anode, calcium chromate cathode, and a solid lithium chloride and potassium chloride electrolyte which are strong oxidizers or caustics capable of causing skin irritation. These batteries may also contain asbestos. If batteries show signs of leakage, proper eye and skin protection is recommended during handling.
The battery manufacturer's Material Safety Data Sheet should always be reviewed for specific environmental and health hazards for the actual battery being used.

Federal Hazardous Waste Requirements
As a generator of a solid waste,Presario V2000(compaq v2000 battery), the generator is required to make a determination as to whether the solid waste is a hazardous waste. This may be accomplished by applying user knowledge or testing the waste.
Typically, hazardous waste classification is based upon the Resource Conservation and Recovery Act (RCRA) Characteristics of Hazardous Waste. Title 40 Code of Federal Regulations (CFR) Part 261, "Identification and Listing of Hazardous Waste," addresses the four hazardous waste characteristics: ignitability; corrosivity; reactivity; and toxicity. A waste is considered a hazardous waste if it exhibits any one or more of these characteristics. The following criteria are used to make these determinations:
Ignitability
A solid waste exhibits the characteristic of ignitability (Environmental Protection Agency (EPA) Hazardous Waste Number D001) if a representative sample of the waste has any of the following properties:
It is a liquid and has a flash point of less than 140 degrees Fahrenheit;
It is not a liquid and is capable, under standard temperature and pressure, of causing fire through friction, absorption of moisture, or spontaneous chemical changes and, when ignited, burns so vigorously and persistently that it creates a hazard;
It is an ignitable compressed gas (as defined in Title 40 CFR 173.300); or
It is an oxidizer (as defined in Title 49 CFR 173.151).
Corrosivity,pavillion zx5000(hp zx5000 battery),
A solid waste exhibits the characteristic of corrosivity (EPA Hazardous Waste Number D002) if a representative sample of the waste is aqueous and has a pH less than or equal to 2 or greater than or equal to 12.5
Reactivity
A solid waste exhibits the characteristic of reactivity (EPA Hazardous Waste Number D003) if a representative sample of the waste has any of the following properties:
It is normally unstable and readily undergoes violent changes without detonating;
It reacts violently with water;

It forms potentially explosive mixtures with water;
When mixed with water, it generates toxic gases, vapors, or fumes in a quantity sufficient to present a danger to human health or the environment;
It is a cyanide or sulfide bearing waste which, when exposed to pH conditions between 2 and 12.5, can generate toxic gases, vapors, or fumes in a quantity sufficient to present a danger to human health or the environment; or
It is capable of detonation or explosive decomposition or reaction at standard temperature and pressure.
