China Emergency Light Manufacturers introduces the types of emergency starting power supplies:
①Traditional flat lead-acid batteries: The advantages are low price, extensive durability, high-temperature safety; disadvantages are bulky, frequent charging and maintenance, dilute sulfuric acid is easy to leak or dry out, and can not be used at low temperatures below 0°C.
② Coiled battery: The advantage is that it is cheap, small and portable, high temperature and safe, can be used at low temperature below -10°C, easy to maintain, and long life; the disadvantage is that it is relatively large in size and weight, and has fewer functions than lithium batteries.
①Polymer lithium cobalt oxide battery: The advantages are small, beautiful, multifunctional, portable, and long standby time; the disadvantages are high-temperature explosion, the low temperature can not be used, complex protection circuit, no overload, small capacity, high-quality products are expensive.
②Lithium iron phosphate battery: The advantages are small and portable, beautiful, long standby time, long life, higher temperature resistance than polymer batteries, and can be used at low temperatures below -10°C; the disadvantage is that the high temperature above 70°C is unsafe, the protection circuit is complicated, and the capacity It is smaller and more expensive than polymer batteries.
Supercapacitors: advantages are small and portable, large discharge current, fast charging, and long life; disadvantages are unsafe at high temperatures above 70°C, complex protection circuits, minimum capacity, and extremely expensive
