Types of batteries Alkaline, Nickel Cadmium, Nickel Metal Hydride and dry cell batteries. These batteries come in sizes ranging from AAA to AA, C, D, 9V and are sometimes rechargeable. Often used in children''s toys, shavers, toothbrushes and torches. Spare or loose batteries must only be packed in carry-on bags.
Lithium batteries can be used instead of Nicad in most cases. And it will not harm the devices. Because the devices require an energy source. When they meet the requirements, the devices will not malfunction. Batteries made of nickel-cadmium can be kept or utilized for up to 5 years. Lithium-ion batteries have a lifespan of two to three years.
Nickel-metal-hydride batteries can leak electrolyte, which is a flammable liquid. So, to sum it up, the reason you can''t pack batteries in your checked baggage is because they can pose a fire risk. Lithium-ion batteries are subject to regulation by the ICAO, and lead-acid and nickel-metal-hydride batteries can also pose a risk.

Nickel-Cadmium (NiCd) batteries are reliable, long-lasting power sources used in many everyday devices like toys, calculators, and power tools. These batteries work through chemical reactions between nickel and cadmium, producing a steady voltage in a compact and lightweight design. They are durable, can handle frequent recharges, and deliver high power
Examples of non-spillable wet batteries: gel batteries or AGM batteries. Examples of dry batteries: nickel metal hydride batteries, nickel cadmium, alkaline manganese or zinc carbon batteries. Transport requirements for non-spillable wet and dry batteries: Non-spillable wet batteries (e.g. gel batteries) must not contain free or unabsorbed liquid.

Keep Nickel Cadmium batteries or the equipment out of the reach of babies and small children, in order to avoid their swallowing batteries. In the event the batteries are swallowed, consult a doctor immediately. Do not charge or use Nickel Cadmium batteries with the + and − terminals reversed. Charging
Do not overcharge Nickel Cadmium batteries by exceeding the predetermined charging period specified by the battery charger's instructions or indicator. If Nickel Cadmium batteries are not fully charged after the battery charger's predetermined charging period has elapsed, stop the charging process.
Do not use or store Nickel Cadmium batteries at high temperature, such as in strong direct sunlight, in cars during hot weather or directly in front of a heater. This may cause leakage of battery fluid. It could also impair performance and shorten the operating life of Nickel Cadmium batteries.
Do not use old and new batteries mixed together or batteries at different charge levels. Do not use the Nickel Cadmium battery mixed together with a dry cell or other battery of different capacity, type or brand name. This may cause leakage of battery fluid and heat generation.
Never modify or reconstruct Nickel Cadmium batteries. Protective devices to prevent danger are built into batteries (single cell or packed cells). If these are damaged, excessive current flow may cause loss of control during charging or discharging of the battery, leakage of battery fluid, heat generation, bursting and fire.
