What is a starting battery

The battery according to the purpose of classification, can be divided into starting battery, power battery and energy storage battery, power battery is common in E-bike, electric vehicle, electric boat, mainly to provide power for these tools; Starting batteries are used in oil-powered vehicles, such as cars, tractors, and motorcycles, to use high power to ignite internal combustion engines.

The starting battery is different from the power battery

The starting battery is applied to the starting of the vehicle, the discharge ability is strong, a short time can release more than 10C current, this characteristic determines its volume and capacity is lower than the power battery. The power battery mainly provides power for the vehicle, the maximum discharge current is not more than 1C, and can not be maintained for a long time, often at less than 0.5C power operation, and the battery life is long, because it needs to store more electricity, so the volume and capacity should be larger.

The material of the starting battery

At present, most of the starting batteries are lead-acid batteries, which is also a relatively large application field of lead-acid batteries. However, due to the gradual attention of environmental protection in various countries, the market for lead-acid starter batteries is gradually compressed, so it is feasible to use lithium iron phosphate batteries as starter batteries.

By analyzing the various requirements for starting the battery, it is easy to draw conclusions. The use of lithium iron phosphate is feasible as long as it can meet the characteristics of small size, high discharge rate, and resistance to low and high temperatures. Compared with lead-acid batteries, using lithium iron phosphate starting batteries has the following advantages:

However, the application of lithium iron phosphate starter battery in the market is limited at present, which may be related to the high initial investment cost of lithium iron phosphate battery. Another important reason is that users have been used to lead-acid battery, have not tried lithium iron phosphate starter battery, and cannot intuitively feel the advantages of lithium iron phosphate battery.
