The degree of battery charge depends on the specific gravity. The electrolyte of a fully charged battery consists of about 64% water and 36% sulfuric acid. It corresponds to a specific gravity of 1,270 kg\/l. As the battery discharges, the specific gravity decreases. By measuring the specific gravity of the electrolyte, we can determine the degree of battery charge. We use a hydrometer to measure the specific gravity of the electrolyte in the battery.[\/vc_column_text][vc_single_image image=&#8221;11967&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; tdc_css=&#8221;eyJhbGwiOnsibWFyZ2luLXRvcCI6IjAiLCJtYXJnaW4tYm90dG9tIjoiMCIsInBhZGRpbmctdG9wIjoiMCIsInBhZGRpbmctYm90dG9tIjoiMCIsImRpc3BsYXkiOiIifX0=&#8221; media_size_image_height=&#8221;200&#8243; media_size_image_width=&#8221;300&#8243; size=&#8221;contain&#8221; height=&#8221;40%&#8221;][vc_column_text css=&#8221;.vc_custom_1658347583490{margin-bottom: 0px !important;padding-top: 10px !important;padding-bottom: 0px !important;}&#8221;]A classic battery hydrometer uses a glass float (hydrometer) in a glass tube to measure the specific gravity of the electrolyte. Squeezing and releasing the rubber ball draws the electrolyte into the hydrometer tube. When filled with test electrolyte, the float floats in the electrolyte. The depth to which the float sinks in the electrolyte indicates its relative weight to water. The value on the float scale in the electrolyte level is gravity. If the hydrometer floats deeply in the electrolyte, the specific gravity is low (A). If the hydrometer floats high in the electrolyte, the specific gravity is high (B).[\/vc_column_text][vc_single_image image=&#8221;11964&#8243; img_size=&#8221;350&#215;327&#8243; alignment=&#8221;center&#8221; tdc_css=&#8221;eyJhbGwiOnsibWFyZ2luLXRvcCI6IjAiLCJtYXJnaW4tYm90dG9tIjoiMCIsInBhZGRpbmctdG9wIjoiMCIsInBhZGRpbmctYm90dG9tIjoiMCIsImRpc3BsYXkiOiIifX0=&#8221; media_size_image_height=&#8221;200&#8243; media_size_image_width=&#8221;300&#8243; size=&#8221;contain&#8221; height=&#8221;40%&#8221;][vc_column_text css=&#8221;.vc_custom_1660650082325{margin-bottom: 0px !important;padding-top: 10px !important;padding-bottom: 0px !important;}&#8221;]\r\n<p style=\"text-align: center;\">Electrolyte gravity measurement<\/p>\r\n[\/vc_column_text]\n <!-- A generated by theme --> \n\n<script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script><div class=\"td-g-rec td-g-rec-id-sidebar tdi_5 td_block_template_1 \">\n\n<style>\n\/* custom css -

These measurements give a good indication of the condition of the battery. Hydrometer readings should not vary by more than a 0.05 kg\/l difference between cells. A larger deviation is an indication that the battery is defective.\r\n\r\nSince temperature affects the specific gravity of the matter, the reading should be corrected by \u00b10.004 for every \u00b110\u00b0C above or below 27\u00b0C. Most hydrometers have a built-in thermometer to measure the temperature of the electrolyte. The hydrometer reading may be incorrect if not corrected.\r\n\r\nWhen the gravity of the electrolyte falls below 1,230 kg\/l, it is necessary to charge the battery.[\/vc_column_text][vc_single_image image=&#8221;11953&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; tdc_css=&#8221;eyJhbGwiOnsibWFyZ2luLXRvcCI6IjAiLCJtYXJnaW4tYm90dG9tIjoiMCIsInBhZGRpbmctdG9wIjoiMCIsInBhZGRpbmctYm90dG9tIjoiMCIsImRpc3BsYXkiOiIifX0=&#8221; media_size_image_height=&#8221;200&#8243; media_size_image_width=&#8221;300&#8243; size=&#8221;contain&#8221; height=&#8221;40%&#8221;][vc_column_text css=&#8221;.vc_custom_1658346912743{margin-bottom: 0px !important;padding-top: 10px !important;padding-bottom: 0px !important;}&#8221;]\r\n<p style=\"text-align: center;\">The relationship of the state of charge of a battery to the gravity of the electrolyte<\/p>\r\n[\/vc_column_text]\n <!-- A generated by theme --> \n\n<script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script><div class=\"td-g-rec td-g-rec-id-custom_ad_1 tdi_6 td_block_template_1 \">\n\n<style>\n\/* custom css -
