Car Battery Life

Li-polymer battery (Li-polymer) Voltage: 3.7V Service life: 500 times Discharge temperature: -20 degrees to 60 degrees Charging temperature: 0 degrees to 45 degrees Remarks: An improved version of lithium battery, there is no battery fluid, and Switching to polymer electrolyte can be made into various shapes and is more stable than lithium batteries.

Lead-acid battery (Sealed) Voltage: 2V Service life: 200 to 300 times Discharge temperature: 0 degrees to 45 degrees Charging temperature: 0 degrees to 45 degrees Remarks: It is a general car battery (it is composed of 6 2V series 12V), the battery life without water is up to 10 years, but the volume and weight are the largest. Model (Chinese standard): Take model 6-QAW-54a as an example:

(1) 6 indicates that it is composed of 6 single cells, each of which is 2V, that is, the rated voltage is 12V.

(2) Q indicates the purpose of the battery, and Q is the battery for starting the car. M is a battery for motorcycles, JC is a battery for ships, HK is a battery for aviation, D is a battery for electric vehicles, and F is a valve-controlled battery.

(3) A and W represent the type of battery, A represents dry-charge battery, W represents maintenance-free battery, if not marked, it represents ordinary battery.

(4) 54 indicates that the rated capacity of the battery is 54 Ah.

(5) Angle a indicates the first improvement to the original product, if b indicates the second improvement, and so on.
