Abstract

A series gas structure lead-acid battery and its composition method, based on multi-cell lead-acid batteries, comprising: A. The side wall (15) between every two single-cell lead-acid batteries is located at the position of the air chamber (16) , open the through hole (18); B. Embed and fix the acid-proof breather (50) at the through hole (18), so as to keep the pressure of each single cell consistent and prevent the electrolyte from escaping, so that each cell inside the battery The electrolyte content between the compartments is adjusted to each other, which improves the uniformity of the float charge voltage and the float charge life of the battery. Moreover, the present invention has low implementation cost, does not increase the volume of the storage battery, and is easy to maintain sealing.

Description

technical field [0001] The present invention relates to accumulators, in particular to lead-acid accumulators, especially to the structure or manufacture of lead-acid accumulators. Background technique [0002] The storage battery in the prior art is either composed of multiple single cells to form a battery pack, or one storage battery is composed of multiple single cells. Due to the difference in the performance consistency of each single cell or each single battery, some batteries will gas out before other batteries and bring out the electrolyte, so that the internal resistance of a single battery will increase due to the loss of electrolyte, and it will be used for a long time. The performance of these batteries will deteriorate and fail in advance, and eventually the performance of the entire battery pack will deteriorate and fail. [0003] In order to solve this technical problem, the Chinese utility model patent CN02286508 discloses a technical solution named "a comb...
