Problems solved by technology

[0003] At present, the flooded starter lead-acid batteries commonly used in the market are tested for their service life according to the service life of GB / T 5008.1-2013 Class B batteries. or equal to 50%C 20 A h, and start the battery at low temperature after 5 units, the low temperature starting current is 0.6I cc A. The starting time is 30s, and the voltage for 30s is required to be greater than or equal to 7.2V. Most batteries can meet the standard requirements, but the surplus capacity is not large, which leads to frequent problems such as premature capacity attenuation and difficulty in starting the vehicle in actual driving. , causing users to complain and return a large percentage of products

Abstract

According to a lead storage battery capable of being normally started in a low charge state, the lead storage battery is a battery of a valve control sealing structure, the needle penetration of positive electrode lead paste is 15-19 mm, and the positive electrode lead paste comprises, by weight, 950-1050 parts of lead powder, 112-117 parts of purified water, 3-5 parts of auxiliary materials, 85-95 parts of dilute sulfuric acid and 1.0-2.6 parts of short fibers. By adjusting the addition amount of water and acid in the positive lead paste, the penetration of the positive lead paste is controlled to be 17 + / -2 mm, the deep cycle life of the battery is prolonged, and the battery still has good starting capability after 209 times of deep discharge cycles.

Description

technical field [0001] The invention relates to a lead storage battery which can be normally started in a low charge state, and belongs to the technical field of storage batteries. Background technique [0002] Heavy-duty trucks, buses, and RVs are mostly long-distance transport vehicles, and it is difficult to avoid non-driving states such as traffic jams, loading and unloading, and rest during their driving. Since the engine needs to continue to work when the on-board electrical appliances such as on-board air conditioners, refrigerators, TVs, water heaters, induction cookers, electric blankets, and audio-visual systems are turned on, the vehicle not only has to bear high fuel consumption costs, but also has to bear the costs caused by engine wear and tear. And the maintenance cost that increases, moreover, engine idle speed running for a long time also can shorten its service life. Therefore, compared with traditional 220V AC power equipment, drivers are more inclined to...
