The No. 5 battery is divided into primary and secondary batteries. Therefore, the capacity of the No. 5 battery can be divided into rechargeable No. 5 lithium battery capacity and non rechargeable No. 5 battery capacity.

Non rechargeable No. 5 batteries are divided into carbon based and alkaline batteries. Generally, the calculation method for the capacity of non rechargeable No. 5 batteries is the time it takes to discharge from the working voltage (1.5V) to the termination voltage (0.9V) at a constant resistance of 3.9 Ω.

Capacity of No. 5 Carbon Battery: Currently, the No. 5 carbon battery on the market is usually a high-power P-type battery. The capacity of No. 5 carbon battery is generally above 55 minutes of discharge, but it varies depending on the design of different manufacturers. A carbon battery with an open circuit voltage of 1.65V from Dongguan Juda can discharge for 90 minutes, making it one of the relatively high capacity No. 5 carbon batteries in the industry.

Capacity of alkaline battery No. 5: Generally, a discharge of 3.9 Ω can last for more than 6 hours, as alkaline batteries can discharge with high currents. Therefore, their capacity can also be measured using constant current discharge. Usually, under low current discharge, the capacity of alkaline battery No. 5 is approximately between 1800~2000mAh.

Rechargeable No. 5 batteries include nickel cadmium batteries and nickel hydrogen batteries. The capacity unit of rechargeable batteries is generally mAh, and occasionally Ah units are used, which are numerically equal to the product of discharge current and discharge time.

Capacity of No. 5 nickel cadmium batteries: Due to environmental regulations, nickel cadmium batteries are gradually being phased out of the market. However, in some situations where low prices are required, nickel cadmium batteries still have a certain market. The capacity of No. 5 nickel cadmium batteries is generally 500-700mAh, and GP, Hitachi, and Panasonic's No. 5 nickel cadmium batteries can have a higher capacity.

Capacity of No. 5 nickel hydrogen battery: Generally, it can reach 1200-1300Ah, which is twice the capacity of No. 5 nickel cadmium battery. Due to its many working advantages over nickel cadmium battery and the development of new applications, No. 5 nickel hydrogen battery has been widely adopted. Famous enterprises such as GP, Japanese companies, domestic companies such as Keliyuan, Dongguan Juda, and Shenzhen Beiteli have achieved large and stable capacity. But the phenomenon of branded nickel hydrogen batteries being counterfeited is also very common.

There is a 14500 lithium battery in lithium-ion batteries, which is also named after the 5th lithium battery due to its similar size. This 5th battery can be designed with a capacity of 500-900mAh, but its charging and discharging life is much longer than that of the 5th nickel hydrogen battery.
