FIELD: electrical engineering; manufacture of lead storage batteries. SUBSTANCE: grid has frame, eyes, pins, varying-section horizontal and vertical ribs forming net inside frame; sectional areas of horizontal and vertical ribs reduce from frame toward center; frame-to-grid thickness ratio in center is 0.98-0.49. EFFECT: reduced lead requirement, improved corrosion resistance of grid, increased service life of battery. 2 cl, 3 dwg |
