Alkaline manganese Batteries

When used correctly, alkaline manganese battery provide a safe and dependable source of power. However, if they are misused or abused, leakage, heating or in extreme case, explosion may result. Therefore pay attention to next point.

• Take care not to touch the chemicals and electrolyte in batteries directly. Since alkaline solution is used in this battery system, there are risks of not only damage of cloth and sore due to adhesion of the solution, but of loss of eyesight if the solution gets into the eye.
  *** In such an emergency case that the solution gets into the eye, wash it immediately with water and receive medical treatment of doctor.
  *** When the solution adheres to the skin and/or clothes, wash it with water and consult a doctor.
• The battery equips the mechanism that release excessive internal pressure to preclude explosion. In case of charge, short-circuit and overdischarge of batteries, the internal pressure may rise abnormally and result in electrolyte leakage by venting. However, the vent mechanism may not work normally depend on circumstances and result in explosion in extreme case.
• The battery heats by short-circuit and the temperature of the battery surface may rise above 100℃.
  

• Always take care to insert batteries correctly with regard to polarity(+ and -), marked on the battery and the equipment. Batteries which are incorrectly placed into equipment may be short-circuit, or charged. This can result in a rapid temperature rise and venting causing leakage and explosion.
• Do not short-circuit batteries. When the positive(+) and negative(-) terminals of a battery are in direct contact with each other, the battery becomes short-circuited. For example, batteries lying on top of each other or mixed together, can be short-circuited. If short-circuited, an excess current flows instantaneously, and this current may cause risks of electrolyte leakage, explosion, etc. due to leakage of battery structure resulted from the heat so generated.
• Do not charge batteries. The batteries are not manufactured to allow charging, therefore, electrolyte leakage and/or damage may occur if charged. If gas is produced abnormally inside the cell by charging, the internal pressure rises and the pressure may result in electrolyte leakage and/or damage of cell. If the charging current is excessively large, much gas generates and there is risk of cell explosion. In the case of charging unused cell, the rate of occurrence of electrolyte leakage, damage, explosion, etc. increases, therefore, attention shall be paid.
• Do not overdischarge batteries. When a battery is left being connected with the electrical circuit (due to forgetting to switch off or the like) after the equipment does not work normally, the consumption of energy is continued inside the battery, the battery becomes overdischarged state, generates gases in its inside and may cause electrolyte leakage or explosion. When two or more batteries are connected for service and the batteries are overdischarged, the battery voltage may become zero V or below (polarity change) and such phenomenon further promote electrolyte leakage and explosion.
• Do not mix batteries. When replacing batteries, replace all of them at the same time with new batteries of the same brand and type. When batteries of different kinds are used together, or new and old batteries are used together, some batteries may be overdischarged due to a difference of voltage or capacity. This can result in leakage and explosion.
• Exhausted batteries should be immediately removed from the equipment and disposed of. When discharged batteries are kept in the equipment for a long time, electrolyte leakage may occur causing damage to the appliance.
• Do not heat batteries. If batteries are heated, the resin part used in batteries melts
  and deforms due to the temperature rise, and electrolyte leakage and explosion may occur.
• Do not directly solder batteries. When a battery is directly soldered, it may be damaged by heat. This may result in leakage, explosion, etc.
• Do not disassemble batteries. Unreasonable disassembling of a battery may result in such risks as injury of the fingers, damage of eye and skin due to scattered chemicals inside the battery.
• Do not deform batteries. Batteries should not be dropped, crushed, punctured, or otherwise mutilated. Such abuse may result in leakage, heat generation or explosion.
• Do not dispose of batteries in fire. When batteries are disposed of in fire, the heat build-up may cause explosion.
• Do not allow children to replace batteries without adult supervision.
• Keep batteries out of the reach of children. Keep batteries which are considered
  swallowable out of the reach of children. Incase of ingestion of a cell or battery, the person involved should seek medical assistance promptly.
• Do not modify batteries. Modification to a battery, may result in blockage of the safety
  vent mechanism and subsequent explosion.
• Store unused batteries in their original packaging and keep them away from metal objects which may short-circuit them.
• Remove discharged batteries from equipment. Remove batteries immediately from equipment which has ceased to function satisfactorily, or when a long period of disuse is anticipated (e.g. video-cameras, photoflash, etc.). The battery that has been partially or completely exhausted may be more prone to leak than one that is unused.

• Avoid rough handling of battery cartons. Rough handling of battery cartons may result in battery damage and impaired electrical performance and may result in leakage, explosion or heat generation.
• Battery cartons should not be piled up in several layers (or should not exceed a specified height). If too many battery cartons are piled up, batteries in lowest cartons may be deformed and electrolyte leakage may occur. As general guide, this height should not exceed 1.5 m for cardboard packs.
• Batteries shall be stored in well-ventilated, dry and cool conditions. Storage at high temperature and high humidity enhances deterioration of the battery performance and promotes electrolyte leakage. For normal storage, the temperature should be between +10℃ and +25℃ and never exceed +30℃. Extremes of humidity (over 95% RH for example) for sustained periods should be avoid since they are detrimental to both batteries and packing. Batteries should therefore not be stored next to radiators or boilers nor in direct sunlight.
• In the storage in warehouse or the display in storefront, do not place batteries in a place exposed to direct sunshine for a long time or splashed by rain water. Exposure to a high temperature increases deterioration of performances and facilitates electrolyte leakage. When batteries get wet, their insulation resistance decreases, self-discharge may occur and rust may be generated.
• Do not mix unpacked batteries so as to avoid mechanical damage and/or short-circuit among each other. When mixed together, batteries may be subjected to physical damage or heat generation resulting from external short circuit. Leakage and/or explosion may then occur. To avoid these possible hazards, batteries should be kept in their packaging until required for use.
• In distribution process such as transportation, display and storage, carry out the first in and first out and take care to avoid storage for a long period.
• Batteries may be disposed of via the communal refuse arrangements provided that no local rules to the contrary exist. At disposal of batteries, insulate terminal parts by winding with tape since external short circuit may occur due to the shape of terminals in 9V square type batteries.

• Design compartments so that batteries are easily inserted and do not fall out, due to slight shock or the like.
• Design compartments to prevent easy access to the batteries by young children.
• Consider the battery dimensions and tolerance when designing the battery compartment.
• Clearly indicate the type of battery to use, the correct polarity alignment and directions for insertion. Further consider the marking of kind (battery system), type, nominal designation shape, nominal voltage and number of batteries.
• Although batteries are very much improved regarding their resistance to leakage, it can still occur occasionally. When the battery compartment cannot be completely isolated from the equipment, it should be positioned so as to minimize possible damage.
• To overcome the problems associated with the reversed placement of a battery, consideration should be given at the design stage to ensure that batteries cannot be installed incorrectly or, if so installed, will not make electrical contact.
• Only the battery terminals should physically contact the electric circuit.
• Battery compartments should be electrically insulated from the electric circuit and positioned so as to minimize possible damage and/or risk of injury.
• Battery compartments should be designed to allow the gas generated from batteries to escape.
• Locate the battery compartment on a place apart from the heat source of the equipment as far as possible.
• When an alternative external power supply is utilized, design the system so that the batteries are not charged. Provide a protective circuit to ensure the prevention of charge of batteries.
• In order to avoid the possibility of short circuits, it is essential that no part of the equipment circuitry (including conductive rivets or screws used to secure the battery contacts, etc.) is allowed to contact the battery case/jacket.
• Precautions during handling of batteries should be described in the handbook of the appliance.
