The improved tubular sealed lead-acid battery has superior cycle life performance and is characterized by providing a gap A between adjacent tubes such that it is expressed by the following equation, in which constant X is within the range of 0.29 - 0.75: A = B x constant X x (1.1 - 0.1 x E) - 2 x C x D where A: the gap between the tubes (mm) B: the inside radius of the tube (mm) C: the thickness of the tube (mm) D: the porosity of the tube (%) x 0.01 E: the inter-electrode distance (mm). <IMAGE>
