Battery — electrolyte replacement (Peugeot 305)

1. If the battery is fully charged, but the specific gravity of the electrolyte in one cell is 0.025 or more lower than the others, check each cell for a short circuit using a voltmeter (a voltmeter connected to a cell for 4-7 seconds should indicate a stable voltage of 1.2-1.8 V). If there is no short circuit, there is an electrolyte leak from one cell.

2. Add a solution of 1 part sulfuric acid to 2.5 parts water to the required jar. If the "jar" is already filled to the top, it is necessary to remove some of the contents of the "jar" with a pipette.

3. When mixing sulfuric acid with water, slowly pour the acid into the water poured into a glass vessel (in no case the other way around). When water is added to sulfuric acid, the mixture may explode.

4. Fill the "can" with fresh electrolyte, recharge the battery and check the electrolyte density again with a hydrometer.
