Battery

There are three kinds of batteries for mobile phones: nickel-cadmium battery, nickel-hydrogen battery and lithium battery. The nickel-cadmium battery has been basically eliminated due to its standby, short talk time and memory effect. The commonly used NiMH and lithium batteries have longer standby and talk time than NiMH batteries under the same volume, but the price is also higher than NiMH batteries. However, no matter what kind of battery you choose, each mobile phone should be equipped with two batteries or a mobile power supply, so as not to delay the call because there is no backup battery.
