Overcharging a lead acid battery can cause the following issues:
• Excessive current will flow into the battery, causing decomposition of water in the electrolyte and premature aging.
• At high rates of overcharge, a battery will progressively heat up.
• Shortened lifespan, decreased capacity, and decreased efficiency.
• Corrosion of the positive battery plates.
• Increased water consumption.
Battery Type Charging Voltage (V) Float Voltage (V)
12V Lead-Acid 14.4 – 14.8 13.2 – 13.8
6V Lead-Acid 7.2 – 7.4 6.6 – 6.9
