Lead-acid battery technology improved by increasing the number and improve the battery plate proportion of sulfuric acid the original design of single-cell system to the 5 6 6 7 system, 7 8 system, even 8 9 system. By thinning the plate thickness and separators car electric toy car battery, to increase the number of plates to increase the battery capacity. The proportion of the original float sulfuric acid batteries are generally between 1.21 to 1.28, while the proportion of sulfuric acid electric bicycle batteries are generally about 1.36 to 1.38 Animal electric toy car battery, which can provide high current, improve battery initial capacity . After years of research, a breakthrough anti-electric car battery fundamentally tandem leaving the battery life is shortened due to technical difficulties, effectively extending the battery life and reduce the maximum technically self-discharge rate, and truly become more durable battery brand. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. Lead-acid battery electric car market the majority of our domestic development Fixed-type batteries are lead-acid battery electric toy car battery, it has a high electromotive force, resistance is small, low cost, stable discharge, etc. professional wholesale electric toy car battery, but there are also short life, lower than the energy production process hazardous and other shortcomings. Fixed-type batteries occupies an important position in power plants, substations and communications sector in the DC system. It is an independent power system requires not only under normal usage control, protective equipment and other critical loads provides reliable DC power supply, and requires in the case of an accident, ensure the provision of reliable DC power supply.
