Common Battery Specifications

AAA, AA, C, D, F, SC, etc. are common markings seen on batteries.

Type of Battery

The mainstream batteries on the market are cylindrical batteries, square batteries, soft pack batteries and so on. In order to adapt to the use of various electrical appliances and optimize the capacity of the battery different types of batteries have different uses.

What are the shapes of batteries?

(1) Cylindrical battery

Cylindrical lithium battery size is standardized various sizes of cylindrical batteries are also different applications, cylindrical lithium battery naming is also related to the size of the commonly used five-digit number indicates that the first two indicate the diameter of the battery, three or four digits indicate the height of the battery, and the last one is often 0, indicating that the round. For example, 10400, 14500, 16340, 18650, 21700, 26650, 32650 and so on.

10400 batteries are commonly used in mini electronic products such as amplifiers, flashlights

14500 batteries are commonly used in digital cameras and electric toys.

16300 batteries are commonly used in headlamps, lighting lamps

21700 batteries: electric cars, LED lights

32650 batteries: solar power generation system, backup energy

(2) Square Battery

The size of the square battery has no prescribed specifications usually customized according to their own use, the application of the square battery is often used for storage batteries, the larger capacity reserve for cell phones and computers, such as charging and discharging energy storage batteries, commonly used for outdoor, indoor and other aspects of the battery requirements of the larger back-up energy reserves.

The model number of the square battery is composed of the positive material and 6 digits, such as ICP103450, which means that the positive material of a square secondary lithium battery is diamond, with a thickness of 10mm, a width of 34mm and a height of 50mm.

(3) Soft pack battery

Soft pack batteries have a soft outer package, the shell does not need steel to protect, soft pack batteries are more often used in lightweight and simple electronic equipment, the capacity of a single battery is also relatively large.

(4) Button batteries

Smaller size for more precise industries such as watches, the use of a small range of

Battery lifespan

Rechargeable battery life is limited, battery charge/discharge cycle will affect the battery life, the battery life of different determines the frequency of your battery replacement.

Rechargeable and disposable batteries

Batteries are divided into rechargeable and disposable batteries, disposable batteries are commonly used in very low power consumption appliances, such as clocks, a battery can be used for about 10 months. But disposable batteries can not be used after a use easy to cause pollution, rechargeable batteries can be recharged again and again, because they can be used again and again to make larger size batteries will not cause waste, the use of disposable batteries are gradually eliminated from the market.

What is the capacity of the battery

Battery capacity often indicates the amount of charge that can be held inside the battery, commonly used ampere-hour and milliampere-hour, indicating that the battery is fully charged with a certain current when working for an hour, usually square battery capacity is the largest.

Battery Discharge

Battery discharge battery voltage is not unchanged, the rated voltage is the voltage of the battery normal discharge, with the reduction of battery power voltage decreases until it can not support the current appliances to use, if the replacement of low-voltage appliances will still respond.

Battery Pack

The same voltage of the battery can also be connected in series and parallel, new energy vehicles or can not meet the current demand for electricity can choose to set up a battery pack, the manufacture of square batteries can be customized, but too huge battery use or the main way to use the battery pack.

Battery power

Battery power is a cross amount of battery to measure the battery performance standards, battery power is generally contrary to the battery life the size of the power to solve the use of the battery range, the power is equal to the voltage × current, such as automotive use of the power of more than 1,000 watts, cell phones, laptops, headphones and other use of the battery’s power in the 5 to 50 watts.

Conclusion

Battery selection should be integrated with the object of use, budget and power, size, capacitance, voltage, battery models are varied before purchase to determine the space and power use is necessary.
