Types of Emergency Car Jump Starter

1.Traditional flat lead-acid battery
The advantage is that it is cheap, extensive and durable, and safe at high temperature; the disadvantage is that it is bulky, frequent charging and maintenance, dilute sulfuric acid is easy to leak or dry up and fail, and cannot be used at low temperatures below 0℃.

2.Winding battery
The advantages are that it is cheap, compact and portable, safe at high temperature, can be used at low temperature below -10℃, simple maintenance, and long life; the disadvantage is that the lithium battery is relatively large in size and weight, and has fewer functions than lithium batteries.

3.Polymer lithium cobalt acid battery
The advantages are compact, beautiful, multi-functional, portable, and long standby time; the disadvantages are that high temperature will explode, low temperature cannot be used, the protection line is complex, cannot be overloaded, the capacity is small, and the high-quality products are expensive.

4.Lithium iron phosphate battery
The advantages are compact, portable and beautiful, long standby time, long life, higher temperature resistance than polymer batteries, and can be used at low temperatures below -10℃; the disadvantages are that high temperatures above 70℃ are not safe, the capacity is smaller than polymer batteries, and the price is more expensive than polymer batteries.

5.Super capacitor battery
The advantages are compact and portable, great discharge current, rapid charging, and long life; the disadvantages are that the high temperature above 70℃ is not safe, the protection circuit is complex, the capacity is the smallest, and the price is extremely expensive.
