Customer ServiceAs we have seen, charging a lead-acid battery with too high of a voltage can be dangerous. Here are some safety measures that I follow when charging my 12-volt lead-acid battery: Always use a charger that is designed for lead-acid batteries. Using the wrong charger can result in overcharging and damage to the battery. Make sure the charger is turned off
Customer ServiceLead-Acid Batteries: Lead-acid batteries require a resting voltage between 12.4 to 12.7 volts when fully charged. This range indicates a good state of charge and promotes longevity. Regularly measuring this voltage helps prevent sulfation, a common issue that occurs when a battery discharges too deeply. According to the Battery University, a
Customer ServiceStandard "12V" Lead-acid batteries are six cells; the peak charge voltage is between 13.8 and 14.7V (at 25C, this value is temperature dependent); however prolonged time at this voltage will cause damage. After the current reaches the cutoff point (3-5% of the C rate of the cell) the voltage should be lowered to 13.5V to 13.8V (the "float voltage").

Customer ServiceThe nice thing about a secondary (rechargeable) lead-acid battery cell is that the discharge cycle is completely reversible. In order to recharge the battery, this electrochemical reaction has to be reversed. When the charging current flows through the battery cell, it causes the conversion of the discharged lead sulfate plates to reverse and forces the sulfate back into the electrolyte. The

Customer ServiceWhat is the float voltage of a 12V lead acid battery? The float voltage of a sealed 12V lead acid battery is usually 13.6 volts ± 0.2 volts. The float voltage of a flooded 12V lead acid battery is usually 13.5 volts. As always, defer to the recommended float voltage listed in your battery''s manual. Some brands refer to float as "standby
Customer ServiceA fully charged lead-acid battery should measure at about 12.6 volts. This is the voltage when the battery is at its fullest and able to provide the maximum amount of energy. When fully charged, a 12-volt battery will have six cells each containing 2.1 volts. What voltage is too low for a 12-volt battery? If the voltage drops below 11.8 volts
Customer ServiceHigher lead acid battery voltages indicate higher states of charge. For instance, 12.6V means a 12V battery is fully charged, while 12.0V means it''s around 50% capacity. Temperature affects voltage, too. Cold temperatures increase the voltage while hot temps decrease it. The charts here assume room temperature.
Customer ServiceEstablishing 25°C (77°F) as the midpoint, the charge voltage should be reduced by 3mV per cell for every degree above 25°C and increased by 3mV per cell for every degree below 25°C. If this is not possible, it is better to choose a lower voltage for safety reasons. Table 2 compares the advantages and limitations of various peak voltage settings.
Customer ServiceKeeping lead acid much below 2.1V/cell will cause the buildup of sulfation. While on float charge, lead acid measures about 2.25V/cell, higher during normal charge. In consumer applications, NiCd and NiMH are rated at 1.20V/cell; industrial, aviation and military batteries adhere to the original 1.25V.

Customer ServiceSo, to answer your question, Yes, 15 volts is too high. Most car alternators, that normally recharge your battery after every start, and provide power while the engine is running, are normally voltage regulated to about 13.8 to 14.0 volts. Up to this voltage and at normal temperatures, the battery will only gas very slightly. Above this, and it
Customer ServiceTemperature affects lead acid battery voltage levels. The voltage level of a lead acid battery increases as the temperature decreases and vice versa. Therefore, you need to consider the temperature when measuring the voltage level of a lead acid battery. At what voltage level is a lead acid battery considered fully charged?
Higher lead acid battery voltages indicate higher states of charge. For instance, 12.6V means a 12V battery is fully charged, while 12.0V means it’s around 50% capacity. Temperature affects voltage, too. Cold temperatures increase the voltage while hot temps decrease it. The charts here assume room temperature.
Being familiar with a lead acid battery voltage chart can help you to understand the state of your battery at a glance. What voltage should a fully charged lead acid battery be? A fully charged lead-acid battery should measure at about 12.6 volts.
The highest voltage 48V lead battery can achieve is 50.92V at 100% charge. The lowest voltage for a 48V lead battery is 45.44V at 0% charge; this is more than a 5V difference between a full and empty lead-acid battery. With these 4 voltage charts, you should now have full insight into the lead-acid battery state of charge at different voltages.
As a lead acid battery discharges, the voltage decreases linearly. For example, a 12V battery may provide 12.6V when fully charged. After discharging halfway, the voltage will drop to around 12.3V. The rate of discharge impacts the voltage. Faster discharge rates result in lower voltages for a given state of charge.
Discharging a lead acid battery below its recommended voltage can cause permanent damage to the battery. It can also reduce the battery’s capacity and lifespan. Therefore, it is essential to avoid discharging the battery below its recommended voltage level. This will ensure its long-term health and performance.
