Comparative analysis of the difference between winding lead-acid battery and conventional lead-acid battery

The principle of winding lead-acid batteries is the same as that of traditional lead-acid batteries. It has only improved the manufacturing process. It is these improvements that make it have better characteristics than traditional batteries. The main performance is in the following aspects:

(1) Excellent high and low-temperature performance

The winding lead-acid battery can work at -55 °C ~ 75 °C. Since the winding lead-acid battery adopts spiral winding technology, the gap between the plate and the plate is very small, and the acid is solid acid and can be absorbed by the fiberglass network. The entire structure is extremely tight. Therefore, at high temperatures, there is basically no bubbling phenomenon, and at low temperatures, there is no liquid acid that can be frozen, and there is no problem of reduced current output. According to the United States SAE test standards, winding lead-acid batteries can be safely and quickly started and towed within the range of -55 °C to 75 °C, while the applicable temperature range of ordinary batteries is generally only -10 °C to 40 °C. This is also the fundamental reason why it can solve the low-temperature conditions of the above-mentioned automatic water condition measurement and reporting system.

(2) Very fast charging

The winding lead-acid battery can charge more than 95 % of the electricity within 40 minutes. Due to the extremely low internal resistance of the winding lead-acid battery, the charging current can be basically accepted, and its own capacity is large. Therefore, there is no current limit when charging, and its general fast charging time can be fully loaded in about 1 hour. The internal resistance of an ordinary battery is high, so part of its charging current will be converted into thermal energy, and its charging time will generally be at least 6 hours or more. The winding lead-acid battery is made of High purity lead, so its side reaction is much smaller than that of an ordinary battery, so the battery can use a small current to charge, and even on rainy days, it can achieve more than 90 % charging efficiency.

(3) Long life

The floating life of the winding lead-acid battery can reach more than 8 years. Since the active lead area of the winding lead-acid battery is very large, its recovery ability after discharge is also extremely strong. According to the US SAE standard, in the J240 test, the number of starts of winding lead-acid batteries is as high as 15,000. Compared with the general power and starting times of general batteries of 2000-4000 times, winding lead-acid batteries have a strong advantage.

(4) Self-discharge minimum

Due to the minimal internal resistance of the winding lead-acid battery, its own self-discharge power is extremely small when idle. The winding lead-acid battery can be placed for two years without charge, so in a sense, it really realizes the non-maintenance. Ordinary batteries can be placed for up to 1-2 months and must be charged.

Due to the above excellent performance, winding lead-acid batteries have been widely used in various fields such as hybrid electric vehicles, electric tools, instrumentation, and wind power generation.
