There are still many brands of electric vehicle batteries on the market today, such as Tianneng, Chaowei, Changxin, Jingqiu, Haibao, etc. These are all well-known brands of lead acid batteries, but I personally think this lead acid When buying lead acid batteries, you do not have to buy big name batteries, as long as they are produced by manufacturers regular, because lead-acid batteries have been developed for more than 100 years and the technology is very mature, so the products produced by major manufacturers In terms of quality, they are basically the same. So what you need to consider at this stage is the price, after-sales and service, and how much it costs. These days, batteries usually have a warranty period, so good after-sales service is king.
Based on the battery product quality, after-sales service and price, we reorder several brands of relatively good lead acid batteries: Tianneng battery, Chaowei battery, Changxin battery and Shinhwa battery, Man Tingfang. battery.
Has Lebanon's battery maker gone bankrupt?
Of course, they're lithium batteries! ! ! The advantages are:
1. Very long lifespan. The lifespan of long-life lead-acid batteries is about 300 times, the maximum is 500 times. However, the lifespan of lithium iron. Phosphate batteries reach over 2,000 times, which is standard. After one charge (5 hour rate), they can be used up to 2,000 times. Lead-acid batteries of the same quality last “six months for new ones, six months for old ones and another six months for maintenance”, or 1 to 1.5 years at most. However, lithium iron phosphate batteries last 7 years. -8 years if used in the same conditions for life". In considerationOverall, the performance-price ratio will be more than 5 times higher than that of lead-acid batteries.
2. It is safe to use. Lithium iron phosphate completely solves the safety risks of lithium cobalt oxide and lithium manganate will explode in strong collision and endanger the lives of consumers. poses a threat, and lithium iron phosphate batteries are characterized by the fact that they will not explode even in the worst road accidents after rigorous safety tests.
3. It can charge and discharge quickly at a high current of 2C. Under a special charger, the battery can be fully charged in 40 minutes at 1.5C, and the starting current can reach 2C. currently do not have this performance.
4. High temperature resistance, the maximum value of lithium iron phosphate electric heating can reach 350℃-500℃, while lithium manganate and oxyde of lithium and cobalt are only about 200℃.
5. With large capacity, the mileage of lithium iron phosphate batteries is 3 to 4 times that of lead acid batteries of the same quality. Its advantages allow electric bikes to travel on a single charge. of moderate weight. It can travel more than 100 kilometers. For office workers, it can be used for about a week on a single charge. The maximum battery capacity of an electric bicycle equipped with a lead-acid battery is 12 Ah as long as the weight of the vehicle does not exceed the standard (the weight of the lead-acid battery has reached 13 kg at this time, while (the weight of the same capacity lithium iron phosphate battery is only 5 kg), it can travel up to about 50 km on a single charge.
6. Rechargeable batteries without memory effect will have lower capacity if they are often fully charged and not fully discharged.Fastment lower than the nominal capacity value, this phenomenon is called memory effect. Nickel metal hydride and nickel cadmium batteries have memory, but lithium iron phosphate batteries do not have this phenomenon. Regardless of the state the battery is in, it can be charged and used at any time, and there is no need to discharge it first. then charge it.
7. Small size and light weight. The volume of a lithium iron phosphate battery with the same specifications and capacity is 2/3 of the volume of a lead-acid battery, and the weight is 1/3. that of a lead-acid battery.
8. Green and environmentally friendly.
Although the price is high, it is still very cost-effective for long-term use·Haha
Battery Lebanon The manufacturer did not make bankruptcy because the Lebanon battery. The current business situation of Zhejiang Lebanon Energy Technology Co., Ltd. continues and has not closed its doors. Zhejiang Lebanon Energy Technology Co., Ltd. is a company dedicated to the production of electricity. batteries, solar cells, lithium batteries and lead acid batteries, so that battery manufacturers in Lebanon do not collapse.
