METHOD OF FILLING SEALED LEAD STORAGE BATTERY WITH ELECTROLYTE Russian patent published in 2010 - IPC H01M10/10 H01M10/06 

FIELD: electrical engineering.

SUBSTANCE: first, storage battery pores volume is filled with liquid electrolyte sulphate, then, remaining volume is filled with gel electrolyte sulphate. Note here that storage battery is filled in two steps: during first step, entire volume of storage battery is filled with liquid electrolyte (sulphuric acid solution). After allowance, electrolyte is rained from storage battery except for that existing in threshold volume of electrode unit. During second step, free volume is filled with young colloid solution of sulphuric acid (sulphuric acid solution with addition of stiffener - aerosil with concentration of (5.6÷9%) with subsequent allowance until colloid solution is completely structured and gel is formed in storage battery.

EFFECT: higher efficiency of filling sealed lead storage batter with electrolyte and specific capacity properties.
