When the energy crisis comes, which is more suitable for household solar energy storage lithium battery or lead-acid battery?

When the energy crisis comes, which is more suitable for household solar Energy storage Lithium Battery or lead-acid battery?

1. Compare the Service history
Since 1970s, lead-acid batteries have been used as backup power supply for residential solar power generation facilities.it`s called deep cycle batteries; With the development of new energy, the Lithium Battery has developed rapidly in recent years and it`s become a new option.

2. Compare the cycle life
The working life of lead-acid batteries is shorter than the Lithium Batteries. The cycle times of some lead-acid batteries are as high as 1000 times, the lithium batteries are about 3000 times. So, During the whole service life of solar power system, the users need to replace lead-acid batteries.

3. Compare the safety performance
Lead acid battery technology is mature and with excellent safety performance; Lithium battery is in the high-speed development stage, the technology is not mature enough, the safety performance is not good enough

4. Compare the Price and convenience
The price of lead-acid batteries is about 1 / 3 of the lithium batteries. The lower cost which makes them more attractive to users; However, the volume and weight of lithium battery with the same capacity are about 30% less than lead-acid battery, which is lighter and save space. However, the limitations of lithium battery is the high cost and low safety performance.

5. Compare the Charging duration
Lithium batteries can be charged faster at a higher voltage, usually within 4 hours, while lead-acid batteries need 2or3 times to be fully charged.

Through the above analysis, I hope it will be helpful for you to choose a suitable battery.
