Can lead acid batteries be charged at low temperatures?

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.

What voltage does a lead acid battery charge?

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.

Should a lead acid battery be a smart charger?

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.

What happens if a lead acid battery freezes?

Charging at cold and hot temperatures requires adjustment of voltage limit. Freezing a lead acid battery leads to permanent damage. Always keep the batteries fully charged because in the discharged state the electrolyte becomes more water-like and freezes earlier than when fully charged.

Can a lead acid Charger prolong battery life?

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.

Tech Note | The Proper Charging of Stationary Lead-Acid Batteries…

Freshening Charge – Lead-acid batteries will self-discharge from the day they are manufactured until they are put into service. As it is often several months before the battery is installed, it is important that a "freshening" charge be given before the battery exceeds its storage shelf life. For lead-antimony or selenium, this is usually 3 months, and for lead-calcium, 6 months. Some ...
