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).
If you suspect your lead acid battery is frozen, here's how you can take care of it: Start by finding out if your lead acid battery is indeed frozen. Turn off the ignition switch and inspect the battery. If the battery fluid is leaking or the battery has signs of damage, don't try to test the battery. Instead, call a mechanic to help you out.
Yes, cold weather does affect the capacity of a lead acid battery. Cold temperatures reduce the chemical reactions within the battery. In colder conditions, the electrolyte solution, usually a mixture of water and sulfuric acid, becomes less effective. This decreases the battery's ability to produce electric current.
The lead acid battery contains lead plates and a mixture of sulfuric acid and distilled water. The battery's fluids form an electrolyte that makes a chemical reaction with the lead plates to create electricity. This electrolyte has a low freezing point and is unlikely to freeze when you have a fully charged battery.
These connections are welded together and when the battery acid freezes it will cause the connections to come apart and the series is broken and the battery can no longer provide the current needed. In most cases, once the battery freezes, it will be ruined. What Do You Do If Battery Acid Is Frozen?
At 32°F (0°C), a lead acid battery can lose about 35% of its capacity. When temperatures drop further, the performance decreases even more. Below 0°F (-18°C), the battery may struggle to start an engine or power devices. Cold weather also increases the internal resistance of the battery.
