Alkaline Batteries Handling Precautions for Safe Use

Alkaline batteries are a safe and reliable power source when used correctly. However, if mishandled, the batteries may leak, overheat, or even rupture. Therefore, please pay attention to the following precautions.

WARNING
  • In case of such an emergency where the solution gets into the eye, wash immediately with plenty of water and receive medical treatment from a doctor.
  • Keep the batteries out of reach of infants and young children. If a battery is swallowed, consult a doctor immediately.
  • Do not dispose of batteries in fire. When batteries are disposed of in fire, the heat build-up may cause explosion.
  • Do not use the battery with the positive ⊕ and negative ⊖ terminals reversed. Batteries which are incorrectly placed into equipment may short-circuit, or be charged. This can result in a rapid temperature rise and venting leading to leakage and explosion.
  • If you lick the alkaline battery solution, rinse your mouth immediately and consult a doctor.
  • If the alkaline battery solution comes into contact with your skin or clothing, it may cause skin damage. Immediately rinse it off with plenty of clean water, such as tap water..
  • Do not connect the positive ⊕ and negative ⊖ terminals of the battery with a wire or carry or store the battery together with metal objects such as necklaces or hairpins. This may cause a short circuit, allowing excessive current to flow, which could lead to leakage, overheating, or rupture of the battery.
  • Do not mix new batteries with used or old batteries, or batteries of different brands or types. Due to differences in their characteristics, there is a risk of leakage, overheating, or even rupture of the batteries.
  • This battery is not designed for recharging. Charging it could damage the insulation or internal structure, potentially causing the battery to leak, overheat, or rupture.
  • Please remove and dispose of the depleted battery from the device immediately. Leaving a used-up battery connected to the device for an extended period may cause gas buildup, which could lead to battery leakage, overheating, rupture, or damage to the device.
  • If you are not using the device for an extended period, please remove the battery. Gas buildup from the battery may cause leakage or damage the device.
CAUTION
  • Do not peel off or damage the battery's outer label. Doing so may cause a short circuit, potentially leading to leakage, overheating, or rupture.
  • Do not subject the battery to impact by dropping or throwing it.This could cause the battery to leak, overheat, or rupture.
  • Do not deform the battery. Damage to the insulation or gas vent could cause the battery to leak, overheat, or rupture.
  • When using the battery in a device with a fully sealed structure, please follow the instructions in the device's user manual.
  • 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 use or leave the battery in high-temperature places, such as under direct sunlight or inside a car on a hot day. This may cause the battery to leak, overheat, or rupture.
  • When storing or disposing of the battery, please insulate the terminals with tape or similar material. Mixing the battery with other batteries or metal objects may cause leakage, overheating, or rupture.
  • If you notice any unusual signs such as heat generation, deformation, or damage to the outer label during use or storage of the battery, please stop using it. There is a risk of leakage, overheating, or rupture.
  • Do not wet the battery with water or other liquids. This may cause the battery to overheat or lead to corrosion on the battery terminals.
  • Batteries may not be compatible with the specifications or performance requirements of certain devices. Please follow the instructions and precautions in the device's manual to ensure the correct use of the appropriate battery for your device.
  • Use and store the battery in a place away from direct sunlight, high temperatures, and high humidity. Exposure to such conditions may cause the battery to leak and could also reduce its performance and lifespan.
  • Please regularly check the batteries in emergency devices or those used for emergency purposes. If not properly maintained, the device may become unusable when needed, or the battery leakage may damage the device.
  • This battery can be disposed of as general non-burnable waste. However, if there are any local regulations, please follow those rules for disposal. Additionally, certain batteries, such as 9V rectangular batteries, may pose a risk of external short circuits due to their terminal shape, so when disposing of the battery, please insulate the terminals with tape or similar materials.

Precautions during handling, transportation, display, storage, and disposal

  1. Avoid rough handling of battery cartons.
    Rough handling of battery cartons may lead to battery damage and impaired electrical performance and may result in leakage, explosion or heat generation.
  2. Batteries shall be stored in well-ventilated, dry and cool conditions.
    Storage at high temperature and high humidity leads to deterioration of the battery performance and electrolyte leakage. For normal storage, the temperature should be between +10°C and +25°C and never exceed +30°C. Extreme humidity (over 95% RH for example) for sustained periods should be avoided since this is detrimental to both batteries and packaging. Batteries should not be stored near radiators, boilers or in direct sunlight.
  3. Battery cartons should not be stacked in multiple layers (or should not exceed a specified height).
    The batteries inside the lower compartment of the packaging box may become deformed and leak.
  4. When batteries are stored in warehouses or displayed in storefronts, they should not be exposed to direct sunlight or rain water for extended periods.
    Exposure to high temperature may increase performance deterioration and risk of electrolyte leakage. If batteries get wet, their insulation resistance decreases, increasing the risk of self-discharge and generation of rust.
  5. Do not mix unpackaged batteries so as to avoid mechanical damage and/or short-circuit of each other.
    When batteries are mixed together, external short circuit may occur, possibly resulting in physical damage, heat generation, leakage and/ or explosion. To avoid these possible hazards, batteries should be kept in their packaging until use.
  6. In transportation, display, and storage, please follow the first-in, first-out principle and ensure that the inventory does not remain for an extended period.

Battery compartment guidelines

  1. Technical Liaison
    It is recommended that companies producing battery-powered equipment should maintain close liaison with the battery industry. The capabilities of existing batteries should be taken into account at design inception. Whenever possible, the battery type selected should be one included in IEC 60086-2. The equipment should be permanently marked with the IEC designation, grade and size of battery which will give optimum performance.
  2. Battery Compartment
    1. Battery compartments should be easily accessible. Design compartments so that batteries are easily inserted and do not fall out. The dimensions and design of compartments and contacts should be such that batteries complying with this standard will be accepted. In particular, the equipment designer should not ignore the tolerances given in this standard, even if a national standard or a battery manufacturer calls for smaller battery tolerances.
    2. The design of the negative contact should make allowance for any recess of the battery terminal.
    3. Equipment intended for use by children should have battery compartments which are tamper-proof.
    4. Clearly indicate the type of battery to use, the correct polarity alignment and directions for insertion.
    5. Use the shape and/or the dimensions of the positive⊕and negative ⊖battery terminals in compartment designs to prevent the reverse connection of batteries. Positive ⊕and negative ⊖battery contacts should be visibly different in form to avoid confusion when inserting batteries.
    6. Battery compartments should be electrically insulated from the electric circuit and positioned so as to minimize possible damage and/or risk of injury. Only the battery terminals should physically contact the electric circuit. Care should be taken in the choice of materials and the design of contacts to ensure that effective electrical contact is made and maintained under conditions of use even with batteries at the extremes of dimensions permitted by this standard. Battery and equipment terminals should be of compatible material and low electrical resistance.
    7. Battery compartments with parallel connections are not recommended since a wrongly placed battery will result in charging conditions.
    8. 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.
    9. The battery compartment shall be clearly and permanently marked to show the correct orientation of the batteries. The reversed placement of one battery in a set, which may result in battery leakage and/or explosion and/or fire. To minimize this hazard, battery compartments should be designed so that a reversed battery will result in no electrical circuit.
    10. The associated circuitry should not make physical contact with any part of the battery except at the surfaces intended for this purpose.
    11. Designers are strongly advised to refer to IEC 60086-5 for comprehensive safety considerations.
  3. Voltage cut-off
    In order to prevent leakage resulting from a battery being driven into reverse, the equipment voltage cut-off shall not be below the battery manufacturers' recommendation.
