How long is the normal service life of lead-acid batteries
The general design float charging service life is more than 5 years, and many manufacturers also claim to be able to use it for 3 years. In fact, most two wheel electric vehicles can only use it for about 1 and a half years, because it has only about 300 cycles of use. The essence of elderly scooters is no different from two wheel electric vehicles, but the frequency of use is not as high as two wheel electric vehicles, which may be slightly longer. However, it is generally 2-3 years, and the usage time is long, resulting in insufficient capacity, You can't run far, so you can't help but change. Please pay attention to the Rongji igniter.
1. After 14 years, the country completely banned batteries containing cadmium because this metal caused too much harm to the human body and environment, directly affecting the organs of the human body. However, cadmium free batteries reduced their range and service life, making the battery life feel different from old batteries, but it is definitely environmentally friendly.
2. Lead-acid batteries have a history of over 100 years, but they have a fatal weakness: sulfurization is irreversible. During charging and discharging, lead sulfate crystals slowly form, causing a decrease in charging and discharging capacity, corrosion of the electrode plates, and reduced capacity and lifespan. That is to say, sulfurization to a certain extent enters the aging period, often only taking one year to repair for half a year, and maintenance and upkeep for another half a year is considered the end.
3. Of course, the number of cycles is only a theoretical value, and most lead-acid batteries will end their lifespan early due to various factors. The early structure is stable, but in the later stage, it will accumulate and deteriorate. There are also a few well maintained batteries that can last for 5 years.
4. Temperature is an important factor, and the higher the temperature, the longer the service life of lead-acid batteries. Of course, it should not exceed 50 degrees, otherwise the negative electrode will be sulfurized and the service life will be reduced in turn. Between 10 and 45 degrees, for each degree of increase, approximately 6 additional cycles of service life will be added.
