Battery charging voltage also changes with temperature. It will vary from about 2.74 volts per cell (16.4 volts) at -40 C to 2.3 volts per cell (13.8 volts) at 50 C. This is why you should have temperature compensation on your lead-acid battery charger or charge control if your batteries are outside and/or subject to wide temperature variations.
Impact of Temperature Variations on Charging Voltage. Battery charging voltage is also subject to temperature fluctuations. At extremely low temperatures, such as -40°C (-40°F), the charging voltage per cell can rise to approximately 2.74 volts, equating to 16.4 volts for a typical lead-acid battery. Conversely, at higher temperatures around
Measuring State of Charge Based on Voltage.
