Lead acid battery vs lithium ion
Household solar battery storage
  1. Compare Service History
Lead-acid batteries have been used as backup power for residential solar power installations since the 1970s. It is called a deep cycle battery; with the development of new energy sources, lithium batteries have developed rapidly in recent years and become a new choice. 
  1. Comparison of cycle life
Lead-acid batteries have a shorter working life than lithium batteries. Some common lead-acid batteries have a cycle count of up to 300, and lithium batteries around 5,000. Therefore, during the entire service life of the solar power generation system, users need to replace the lead-acid battery.
  1. Compare safety performance
Lead-acid batteries have mature technology and excellent safety performance; lithium batteries are in the stage of rapid development, the technology is not mature enough, and the safety performance is not good enough. With the development of technology, the safety problem of lithium battery has been solved. Lithium battery has BMS management system, with overcharge, overdischarge, overcurrent, short circuit and other protections to ensure the safety of the battery pack, especially the main phosphoric acid Iron-lithium battery, high safety performance, no explosion and no fire. 
  1. Compare price and convenience
Lead-acid batteries are about one-third the price of lithium batteries. The lower cost makes it more attractive to users; but the volume and weight of lithium batteries with the same capacity are about 30% less than that of lead-acid batteries, which is lighter and more space-saving. However, the limitations of lithium batteries are high cost and low safety performance. Although with the same voltage and capacity, lead-acid batteries are cheaper than lithium batteries. However, the cycle life of ordinary lead-acid batteries is only about 300 times and the service life is 1-2 years. The current lithium iron phosphate battery has a guaranteed minimum cycle life of more than 2,000 cycles, about 5,000 cycles practical performance and more than 10 years service life. Comprehensive comparison, the cost of lithium iron phosphate batteries is lower.

  5.Compare charging timeLithium batteries charge faster at higher voltages, typically within 1.5 hours, while lead-acid batteries take 4 to 5 charges to fully charge. 6.Compare Enviromental ProtectionLithium battery does not contain any harmful heavy metal elements, pollution-free both in production and actual use. As long as lead acid batteries are used, there will always be pollution rates several times as high as their gasoline counterparts. It is estimated that 44%–70% of the lead from lead acid batteries in the PRC is released into the environment as waste. 7.Compare WeightLiFePO4 substitution battery is only approx. 1/3 of lead acid battery in weight;. It can Facilitate transportation, installation, storage. 8.Compare UseLithium battery are more easier to install and use. Our home energy battery just plug and play to minimize the installation time and cost. Compact and fashionable design fits in your sweet home environment. You can save lots of time and money. Through the above analysis, I hope it will be helpful for you to choose the right battery. In my opinion, lithium battery are better than lead-acid battery in home energy storage. We also provide some home battery for you. If you have any question, contact us now.
