What is the difference between the life of a lithium battery and a lead-acid battery
Now the number of lithium battery electric vehicles is slowly increasing, but many friends still choose to continue to use lead-acid batteries, since the price is cheap, and secondly, maintenance and replacement are convenient!
Today we will talk about the difference between the life span of a lithium battery and a lead-acid battery with the same capacity?
Let’s take the same 48V battery as an example. When both are fully charged, the range of the lead-acid battery is similar to that of the lithium battery! The difference is in the use of cycle life!
The number of cycles of lead-acid batteries on the market is around 300–500. The service life of lithium batteries will be longer, and the number of cycles is generally around 2000–3000.
That is to say, the capacity of the lead-acid battery needs to be fully charged and discharged about 500 times before the capacity drops! According to the habit of charging once every 2 days, the service life of lead-acid batteries is about 2 years!
In terms of service life, there are pros and cons to choose lead-acid or lithium battery. But the only drawback of lithium batteries is safety, which needs to be improved.
