Battery Characteristics

Characteristics and applications of batteries

Characteristics and applications of batteries are taken into consideration when designing the electronic device. For instance, an electric screwdriver requires batteries that are able to carry higher current, short charging interval, and lighter weight. Therefore, Ni-CD batteries are ideal for this equipment.

However, if Li-ion batteries were chosen, they would not be able to supply sufficient power when discharging and could lead to damages to the batteries in the process.

In general, batteries are pre-assembled by manufacturers in the form of a Battery Pack for specific applications on electrical devices. A single battery pack comprises of one or several rechargeable batteries connected in series or in parallel modules such as NTC, PTC, Thermostat, poly switch, and packaged in a sealed plastic case. For instance, a cellular phone battery consists of a single Li-ion battery (3.6v 6/mAh) and a battery protection module, and is sealed in a plastic case.

Batteries vary in shape and dimensions to correspond with the different cellular phone designs. Battery Packs are for more advanced products such as notebooks and PDA, which provides power management functions and enhanced safety features.
