Laptop batteries

Laptop batteries come in many shapes, sizes and capacities. The most common type is the lithium-ion battery, which is long-lasting but can be prone to overheating if not properly maintained. Other types of laptop batteries are nickel metal hydride (NiMH) and nickel cadmium (NiCd). NiMH batteries have a lower capacity than lithium-ion batteries, but can be recharged more frequently without damage. NiCd batteries are cheaper to buy, but have a much lower capacity than the other types and need frequent recharging.

When buying laptop batteries, it is important to consider both the capacity and the number of charging cycles. Capacity is measured in milliamp-hours (mAh) and indicates how long a battery can last before it needs to be charged. The number of charge cycles indicates the number of times a laptop battery can be depleted and recharged without losing its capacity.

Also, look for batteries with overload protection, which prevents them from being damaged by an overcharged power supply. Finally, laptop batteries should be physically and electronically suitable for your laptop. Before you buy a new battery, make sure that the connectors are compatible with your laptop's charging port.

Proper care and maintenance of your laptop batteries can ensure years of reliable operation. By understanding the different types of batteries and their capabilities, you will be better prepared to make an informed decision when buying new laptop batteries.
