The 5th battery is divided into a primary battery and a secondary battery. Therefore, the 5th battery capacity can be divided into the rechargeable 5th lithium battery capacity and the non-rechargeable 5th battery capacity.
Non-rechargeable No. 5 batteries are divided into carbon and alkaline batteries, usually, non-rechargeable No. 5 battery capacity is calculated by: 3.9Ω constant resistance discharge from the operating voltage (1.5V) to the termination voltage (0.9V) The length of time.
No. 5 carbon battery capacity: At present, the No. 5 carbon battery on the market is usually a high-power P-type battery. No. 5 carbon battery capacity is generally more than 55 minutes of discharge, but it is different due to different manufacturers' designs. A gold-carbon battery with an open circuit voltage of 1.65V can discharge for 90 minutes. It is a carbon battery with a relatively high volume of capacity in the industry.
No. 5 alkaline battery capacity: Under normal circumstances, 3.9Ω discharge up to 6 hours or more, because the alkaline battery can discharge with a large current, so you can also use constant current discharge to determine its capacity. In general, the capacity of alkaline cell No. 5 is about 1800~2000mAh under small current discharge.
The rechargeable No. 5 battery has a nickel-cadmium battery and a nickel-hydrogen battery. The rechargeable battery capacity unit is generally mAh. Occasionally, the Ah unit is used, which is numerically equal to the product of the discharge current and the discharge time.
No. 5 nickel-cadmium battery capacity: due to environmental protection regulations, nickel-cadmium batteries are gradually out of the market, but in some occasions require low prices nickel-cadmium batteries have a certain market, 5th nickel-cadmium battery capacity is generally 500 ~ 700mAh Among them, GP 5, Nissan, Panasonic's No. 5 NiCd battery capacity can be made higher.
No. 5 NiMH battery capacity: generally can be achieved 1200 ~ 1300mAh, is twice the capacity of No. 5 nickel-cadmium battery, because nickel-metal hydride battery has many work advantages than nickel-cadmium battery, and has been developed a new use, so To be widely adopted, the No. 5 nickel-metal hydride battery has a large and steady capacity of GP, Japanese companies, domestic Keliyuan, Shenzhen Jinkaieng, and Shenzhen Beiteli. However, the phenomenon of counterfeiting nickel-metal hydride batteries is also very common.
Lithium-ion battery has a 14500 lithium battery, because of its size and its close to the 5th battery, it is also named the 5th lithium battery, this 5th battery capacity can be designed to 500 ~ 900mAh, but its charge and discharge life But far more than 5 nickel-metal hydride batteries.
