Abstract Using lead-acid battery for the back-up power system of pitch is adopted by majority manufactures. The cost of lead-acid battery is low, but the lead-acid has some disadvantages such as high fault rate, low lifetime, due to the affection of temperature and self-character. The pure-lead battery has obvious advantages compared to lead-acid battery. Firstly, the problems on the lead-acid back-up power systemwere analyzed. Secondly, the advantage of pure-lead batterywas indicated. Lastly, the design plan of the back-up power system based on pure-lead batterywas introduced in detail. Meanwhile, the test data at the windfarm was suppliedto prove the fact that pure-lead battery back-up power system is one executable way of solving to the high fault rate of lead-acid battery back-up power system.
