Embodiment 1
[0023] A starter lead-acid battery suitable for use in a low state of charge. The starter lead-acid battery is a battery with a valve-controlled sealed structure, and the positive lead paste includes the following components by weight: 1000 parts of lead powder, 112 parts of purified water, 4 parts of auxiliary materials, 90 parts of dilute sulfuric acid and 1.8 parts of short fiber.
[0024] The mixing process of the positive lead paste is as follows: add 1000kg of lead powder, 4kg of alkaline earth metal oxide and sulfate mixture, and 1800g of short fibers into the mixing machine, stir evenly for 5 minutes, then open the water valve, and pour the mixture into the mixing machine at an even speed. Add 112kg of purified water, the water addition time is 1-3 minutes, stir while adding water, the stirring time is 5 minutes, then open the acid addition valve, add dilute sulfuric acid 90kg to the paste machine, the acid addition time is 14-18 minutes, and Turn on the dust extractio...
