Starter batteries, semi-traction batteries, traction batteries, and even stationary batteries all need maintenance to perform to their full potential. Regularly perform the six essential maintenance tasks we outline here to optimize the performance and reliability of your lead-acid batteries.
How do you prevent a lead acid battery from corroding?
To prevent this, charge lead acid batteries for a long time at a low charging current. Battery cell terminals are prone to corrosion, especially at the bolted connections. To prevent this, regularly check bolt tightness and cover connections with petroleum jelly. Replace any corroded cells immediately.
How often should a lead acid battery be recharged?
Sealed lead acid batteries need to be kept above 70% State of Charge (SoC) during storage. If you’re storing your batteries at the ideal temperature and humidity levels, then a general rule of thumb would be to recharge the batteries every six months. However, if you’re unsure, you can check the voltage to determine if a recharge is necessary.
How do you clean a lead-acid battery?
Maintaining a clean battery surface is crucial for the longevity of your lead-acid battery. Dirt and grime can cause the battery to discharge across the grime on top of the battery casing. To clean the surface of the battery, follow these steps: Remove the battery from the vehicle or equipment. Mix a solution of baking soda and water.
How long do lead-acid batteries last?
Lead-acid batteries typically last between 3 to 5 years, but with regular testing and maintenance, you can maximize their efficiency and reliability. This guide covers essential practices for maintaining and restoring your lead-acid battery. What are lead-acid batteries and how do they work?
