Frequently Asked Questions
How Does a Car Battery Work?
Most, but not all, passenger vehicles on the road use what’s called a “lead-acid battery.” Inside the sturdy plastic casing are several metal plates surrounded by sulfuric acid. A reaction between the two takes place, which produces chemical energy. The battery then converts the chemical energy into electrical energy, which starts and powers your car.
Can My Car Battery Freeze?
A fully charged lead-acid battery has a freezing point of below -40F. However, most sulfate ions are consumed if the battery is fully discharged. An electrolyte solution comprised mostly of water with a freezing point of 32F.
How much does it cost to get a battery replaced?
Depending on size, quality, and power, it will cost around $45-$250.
The battery won’t accept a charge current for those who live in cold climates to come out to your car on a freezing day. At this point, it will need to be warmed up before accepting a charge. Once it’s charged up completely, it won’t freeze until it’s fully discharged again.
