Protective maintenance improves safety and reliability

　　Most battery manufacturers recommend replacing the Sealed 12v Battery that loses efficiency. These Sealed 12v Battery work better when fully charged, so when their capacity is below 50% or after 30 days of storage, you should charge them.

　　When the power is less than 40% of the capacity, the electrolyte in the Sealed 12v Battery may freeze.

　　When water and internal liquid are converted to lead sulfate and separated from the mixture and settle to the bottom of the battery, battery delamination occurs.

　　Delamination will reduce battery power, causing the battery to overheat, evaporate water, corrode and eventually fail.

　　Regular charging of the Sealed 12v Battery can prevent delamination, freezing, and degrading battery performance.

　　Depending on temperature and storage conditions, all batteries will lose power over time. At 80 degrees Fahrenheit, lead-acid batteries lose 4% of their power every week. A 125 amp-hour battery will lose 80 amps in four months, so keeping it charged is essential to protect your power source.

　　Regularly clean cables and connectors with a hard steel brush to remove corrosion and optimize electrical connections.

　　You can scrape off the inside of the connector with a knife, strip the soft lead, and expose the bright metal.

　　When handling the battery, always wear safety glasses and protective gloves.

　　Small particles may spread in the air, and overfilling the reservoir may cause explosive emissions.

　　By adding a thin layer of protective lubricant to the battery terminal to limit further battery corrosion.
