As temperatures have been well below freezing this winter you may be wondering if your lead acid batteries can freeze. The simple answer is yes. Here's why, if your battery is partially discharged, the electrolyte in a lead acid battery can actually freeze.
This is for lead acid type batteries. Car batteries, for example. Or those which typically install in lawn tractors, ATV’s, snowmobiles, maybe in your camper, etc.. To put it another way, a lead acid battery freezing point will be -40F if it’s down 20% from a full charge. Or -22F if it’s down 40% from full charge.
This is a good idea. Better safe than sorry, right? However, you can leave a lead acid battery installed during the winter. But only if the battery is in good condition, there is no parasitic load slowly draining the battery, and the battery is fully charged. I keep trickle chargers on mine, just in case.
As the state of charge in a battery decreases, the electrolyte becomes more like water and the freezing temperature increases. The freezing temperature of the electrolyte in a fully charged battery is -92º F (-69º C). At a 40% state of charge, electrolyte will freeze if the temperature reaches approximately 16º F (-9º C).
To charge a lead-acid battery, first connect the charger to the battery system before powering up or plugging in the charger. Another caution for discharged batteries: The electrolyte at this point is mostly water and will freeze at a higher temperature (15 to 20 degrees F.) than a fully charged battery.
The only way that a battery can freeze is if it is left in a state of partial or complete discharge. As the state of charge in a battery decreases, the electrolyte becomes more like water and the freezing temperature increases. The freezing temperature of the electrolyte in a fully charged battery is -92º F (-69º C).
