Here are some key points to keep in mind: 1. Reduced Charge Acceptance: At low temperatures, lead acid batteries experience a reduced charge acceptance rate. Their ability to absorb charge is compromised, resulting in longer charging times. 2. Voltage Dependent on Temperature: The cell voltages of lead acid batteries vary with temperature.
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.
To mitigate these issues, it is essential to charge lead acid batteries at elevated temperatures. In low temperature charging scenarios, it is recommended to use a charger designed for cold conditions, which typically feature higher charge voltages. This compensates for the reduced charge efficiency caused by the colder environment.
