This blog covers lead acid battery charging at low temperatures. A later blog will deal with lithium batteries. Charging lead acid batteries in cold (and indeed hot) weather needs special consideration, primarily due to the fact a higher charge voltage is required at low temperatures and a lower voltage at high temperatures.
A lead acid battery charges at a constant current to a set voltage that is typically 2.40V/cell at ambient temperature. This voltage is governed by temperature and is set higher when cold and lower when warm. Figure 2 illustrates the recommended settings for most lead acid batteries.
SOME FACTS ON THE SUBJECT OF AMBIENT OR OPERATING TEMPERATURE. As a general rule, Banner recommends an operating temperature of max. -40 to +55 degrees Celsius; optimum storage conditions are approx. +25 to +27 degrees Celsius. These criteria apply to all lead-acid batteries and are valid for conventional, EFB, AGM and GEL technology.
Heat is the worst enemy of batteries, including lead acid. Adding temperature compensation on a lead acid charger to adjust for temperature variations is said to prolong battery life by up to 15 percent. The recommended compensation is a 3mV drop per cell for every degree Celsius rise in temperature.
Lead-acid batteries: A lead-acid battery should come with a smart charger that allows for voltage changes when sensing fluctuating temperature ranges. It should set the voltage higher when the battery is charged at lower temperatures and a lower voltage when charging at higher temperatures.
Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems) With the CCCV method, lead acid batteries are charged in three stages, which are constant-current charge, topping charge and float charge.
A lead acid battery works best between 20°C and 30°C (68°F to 86°F). While it can handle higher temperatures, going beyond 30°C (86°F) can reduce its service life.
