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.
However, a well charged lead acid battery in good condition will not freeze in practical use. But the less charged it is, the more susceptible to freeze damage. Even for a fully charged lead acid battery, there’s still a point of freezing. But those temperatures are extremely cold and you likely will not ever experience that cold (keep reading).
Good quality lead batteries perform reliably when exposed to extreme environments and have a wide operating temperature, ranging from -40°F to 120°F. Lead batteries are also more forgiving when subjected to temperature extremes. For extreme temperatures, it may be best to install batteries that are purpose-built for difficult applications.
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.
But Lead-acid batteries can be charged and discharged from -4°F to 122°F. It’s very important to be aware of the charging temperatures that a battery can accommodate. If batteries don’t operate at the accepted temperature, charge acceptance will be decreased because ion combination will be slower.
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.
