The meanings of P+, TH, ID and P- are respectively: positive pole of P+ battery; TH detection pole output (used to detect and display the battery usage status, grounded identification detection terminal); pole.
Batteries used in digital cameras typically use two 1.5V cylindrical batteries or a single 3.7V square lithium-ion battery. Old-fashioned digital cameras typically use AA batteries or AA batteries, and users who do not use digital cameras often use higher quality alkaline batteries.
Detailed information:
Digital cameras use AA batteries or AA batteries, and users who do not frequently use digital cameras should use higher quality alkaline batteries. . Since alkaline batteries are cheap andhave more power than nickel-metal hydride batteries, although the batteries run out during use, they can be easily purchased in small stores everywhere.
In electricity, concepts such as voltage and capacity are commonly used to measure the properties and performance of individual batteries. Generally, the rated voltage of a single dry battery (including alkaline battery) is 1.5V, nickel-cadmium battery and nickel-hydrogen battery are 1.2V, and lithium-ion battery is 3.6V, which is equivalent to the voltage obtained by connecting 3 nickel-cadmium or nickel-hydrogen batteries in series. Some common non-rechargeable lithium batteries have a voltage of 3V.
