Will86 Posted December 3, 2019 Share Posted December 3, 2019 Does the surrounding temperature have an effect on the time it takes? i.e. Winter or summer Link to comment Share on other sites More sharing options...
spirou Posted December 3, 2019 Share Posted December 3, 2019 Ideally the charger will have a temperature sensor to a) adjust charging rate/voltage to the battery temperature and b) adjust the same if itself is overheating. Also, lead batteries typically have a temperature coefficient of around -16mV/°C (12V battery) so the hotter it gets, the lower the voltage and vice versa. So around freezing, the charging voltage should be about 0,3V higher. Whether that will have any effect on charging time... I don't really know. It's hard to compare outside the lab. However, charger overheating will definitely extend the time it takes. Link to comment Share on other sites More sharing options...
