Ni-Cd battery（Nickel-Cadmiun Battery） is one of the earliest rechargeable batteries adopted in our daily life. The prosperous development of scientific and technological industries renders technical support to the progress of batteries. Meanwhile，higher requirements are put forward for quality and function of the batteries，facilitating the updating of batteries. Rechargeable Ni-MH battery (Nickel Metal Hydride Battery), which affirmatively meets the demands raised by the new era，emerges at the right moments and gradually replace Ni-Cd batteries.
It is universally acknowledged that rechargeable Ni-MH battery has enjoyed popularity in the market today，which also propels BPI to make unremitting efforts to manufacture the best Ni-MH batteries for customers. So what are the differences between rechargeable Ni-MH battery and Ni-Cd battery?
Let us briefly introduce you some main differences between Ni-MH and Ni-Cd batteries. Hope it will help you to make an optimal choice when choosing a battery.
The battery capacity of a rechargeable Ni-MH battery exceeds the battery capacity of a Ni-Cd battery. Memory effect lowers the capacity of the Ni-Cd battery negatively，thus shorten its standard lifespan. The memory effect refers to the battery power doesn’t run out completed before it is charged. Under such a circumstance，some small bubbles will be produced during the process of charge and discharge，thus reducing the area of the battery plate and indirectly affect the capacity of the battery. In the contrast，the best Ni-MH batteries avert the memory effect thus gaining larger battery capacity and longer lifespan. At the same time，higher capacity density allows the rechargeable Ni-MH battery to extend its working time of the equipment.
Generally speaking，rechargeable Ni-MH battery，which is devoid of memory effect，will be more secured and have a higher output current than the Ni-Cd battery. Hence, it will be relatively suitable for high power consumption products and an extensive working time. Although the Ni-MH battery is not resistant to recharge，BPI is sparing efforts to improve its technology and provide the best Ni-MH batteries.
Compared with Ni-Cd batteries，rechargeable Ni-MH batteries will be more environmental-friendly. Owing to cadmium，which is detrimental to the environment，Ni-Cd batteries will trigger environmental hazards and must be recycled. Rechargeable Ni-MH batteries don’t contain toxic materials，so the batteries are more environmental- friendly and can be immune from being recycled. What is worth noting is that the best Ni-MH battery has been supposed to be one of the most environmental-friendly batteries in the world today，which are also widely utilized by advanced countries in Europe and the United States.
Although the rechargeable Ni-MH battery is slightly better than Ni-Cd battery in capacity, output voltage and environmental friendliness, Ni-Cd battery also has its unique advantages. In fact, Ni-Cd battery is the only battery with good performance under strict working conditions. Besides, Ni-Cd battery prefers fast charging to slow charging. Among rechargeable batteries, Ni-Cd battery remains a popular choice for applications such as two-way radios, emergency medical devices and power tools.
