Product Overview
Brand NOVEX The sealed lead-acid battery consists of six cells mounted side by side in a single case. The cells are coupled together, and each 2.0V cell adds up to the overall 12.0V capacity of the battery. Despite being relatively heavy, lead-acid batteries are still preferred over other lightweight options owing to their ability to deliver large surges of electricity (which is required to start a cold engine in an automobile). A completely charged lead-acid battery is made up of a stack of alternating lead oxide electrodes, isolated from each other by layers of porous separators. All these parts are placed in a concentrated solution of sulfuric acid. Intercell connectors connect the positive end of one cell to the negative end of the next cell hence the six cells are in series. When the battery is discharged, it acts as a galvanic cell and the following chemical reaction occurs. Negative: Pb(s) + HSO4 + H2O(l) > 2e + PbSO4(s) + H3O+(aq) (oxidation) Positive: PbO2(s) + HSO4(aq) + 3H3O+(aq) + 2e > PbSO4(s) + 5H2O(l) (reduction) Lead sulfate is formed at both electrodes. Two electrons are also transferred in the complete reaction. The lead-acid battery is packed in a thick rubber or plastic case to prevent leakage of the corrosive sulphuric acid. The sulphuric acid existing in the lead discharge battery decomposes and needs to be replaced. Sometimes, the plates change their structure by themselves. Eventually, the battery becomes less efficient and should be charged or changed. When car batteries spend considerable durations of time in their discharged states, the lead sulfate build-up may become extremely difficult to remove. This is the reason why lead-acid batteries must be charged as soon as possible (to prevent the building up of lead sulfate). Charging of the lead batteries is usually done by providing an external current source. A plug is inserted which is linked to the lead-acid battery and the chemical reaction proceeds in the opposite direction. In cases where the sulphuric acid in the battery (or some other component of the battery) has undergone decomposition, the charging process may become inefficient. Therefore, it is advisable to check the battery periodically.
