How do you know the capacity of a 12V battery?

There was sign on general battery housing. For example, 12 v 7.2 AH is the battery capacity [12 v multiply by 7.2 A is equal to 86.4 W]. If it is old battery, you need to go to the electronic measuring instrument shop to buy battery capacity meter for testing. The price is about one hundred yuan.

The capacity of the battery voltage is 12 v 2.2 AH, July 14 AH, AH, AH, AH, AH, and 45 80 AH AH, AH, 60, 80 120 AH AH, AH, AH 160, 120.

Chemical energy is converted into electrical energy device is called chemical battery, commonly referred to as "for the battery. After discharge, can make the internal active substances in charging way - to store the electric energy to chemical energy regeneration; When need to discharge to convert chemical energy to electrical energy again. Call this type of battery storage battery (storage battery), also known as the secondary battery.

So-called is chemical energy storage battery, a necessary release electricity an electrochemical device.

Combinations: ICR18500-3 s2p nominal voltage: 11.1 V discharge voltage: 11.1 V to 11.1 V regular discharge current is: 0-2 a large capacity for 3-4 a nominal capacity: to Mah A, there are a variety of standard lasts discharge current: 0.2 C maximum continuous discharge current: 1 C working temperature: charging: 0 ~ 45 ℃ discharge: - 20 ~ 60 ℃ product size: MAX39 finished resistance: * 56.6 * 99 mm, 280 m or less Ω standard weight: protection board: IC - S8254AAJ + MOS - AO4409 lead models: JST - positive plug UL1007 VHR - 2 p / 24 # line, the line is 100 mm long protect parameters: the overcharge protection/each string of 4.35 + / - 0.025 V voltage discharge voltage protection over-current value: 2.4 + / - 0.08 V 10 ~ 25 A 12 v lithium-ion battery specification: voltage: The 12 v battery capacity: there is no standard capacity, capacity is according to use electrical appliances, or equipment to determine the specific requirements, the general capacity of: 2200 ma/h, 5 ah, 10 ah, some electric capacity up to 20 ah, or 50 ah. Batteries in parallel, the more the greater the capacity. According to the physics formula: in the parallel circuit: I always = I1 + I2 + I3 volume: 12 V lithium battery volume, according to battery capacity to identify, no unified specification. Battery capacity is larger, the greater the volume weight: now a lot of equipment are in need of large capacity, light weight some lithium batteries, such as electric, is to use lead-acid batteries before, now a lot of electric cars to lithium batteries, because of large capacity of lithium battery, light weight, small volume. Charge and discharge current: the lithium battery charge and discharge current, it is according to the equipment, the power to determine the electrical: P = UI. On the basis of constant voltage, the greater the power of equipment, the more the need of the output current.12 v lithium-ion batteries use: electric cars, electric tools, laptop, mobile DVD, UPS, GPS, medical equipment, etc.

The 12 v lithium-ion batteries with 3 or 4 in series with the lithium battery. Combined into the battery, battery capacity, according to the capacity of a single cell or in parallel with the capacity of the battery to determine, is a safe, environmental protection a new type of battery.

The 12 v battery: according to the material classification, can be divided into: 12 v lithium battery, 12 v lead-acid battery, 12 v nickel cadmium batteries, nickel-metal hydride 12 v alkaline battery.12 lithium-ion batteries, is made up of three 3.7 V lithium battery series combination, after a single lithium battery charge voltage of 4.2 V, usually also called 4 V, in series with the battery voltage, both: 4 V/a * 3 battery also = 12 V, is what we call the 12 V lithium-ion batteries, combination as shown in the figure below

The 12 v lithium battery specifications:

Voltage: 12 v

There is no standard capacity, battery capacity: capacity is according to use electrical appliances, or equipment to determine the specific requirements, the general capacity of: 2200 ma/h, 5 ah, 10 ah, some electric capacity up to 20 ah, or 50 ah. Batteries in parallel, the more the greater the capacity is. According to the physics formula: total in the parallel circuit: (I) = I1 + I2 + I3 [1]

Volume: the volume of a 12 v lithium battery, according to the capacity of the battery to determine, not unified specification. The bigger the battery capacity, the greater the volume

Weight: now a lot of equipment are in need of large capacity, light weight some lithium batteries, such as electric, is to use lead-acid batteries before, now a lot of electric cars to lithium batteries, because of large capacity of lithium battery, light weight, small volume.

Charge and discharge current: the lithium battery charge and discharge current, it is according to the equipment, the power to determine the electrical: P = UI [1].On the basis of constant voltage, the greater the power of equipment, the more the need of the output current.

12 v lithium-ion batteries use: electric cars, electric tools, laptop, mobile DVD, UPS, GPS, medical equipment, etc.
