Best Car Battery For Cold Weather: Buying Guide

A harsh cold means you’ll be struggling a lot more with your car battery. Chilly mornings where your car has cold start issues are no less than a nightmare. So there are factors that you need to double-check before you purchase a car battery, especially if you reside in colder regions. The most crucial ones have been mentioned below.
Cold Cranking Amps
This is the first and foremost feature that you should look for in a battery if you want it to withstand all the chills. The CCA rating of a battery refers to the number of amps it offers at freezing temperature. The higher this rating, the better it’ll perform in cold weather by providing enough amps to get the engine started.
Maintenance Free
AGM batteries are generally referred to as maintenance-free batteries. The AGM plates function by absorbing the electrolyte in the battery and hence, eliminate any risk of spillage. 
 
This offers great mounting flexibility. In addition to that, AGM batteries tend to perform better in cold weather than standard batteries. This is because they offer higher CCA ratings and have lower self-discharge rates. And both are essential for a battery to perform in the harsh cold.
Reserve Capacity
Reserve capacity of a battery is essential for all the times the charging system or alternators of the vehicle fail to respond. It refers to when a fully charged battery can deliver 25 amps of current before the voltage falls to 10.5V. 
 
So this factor shouldn’t be overlooked because it’ll be responsible for meeting the electronic demands of a car when needed. A battery’s reserve capacity is measured in amp-hours, and this rating is better when it’s higher.
Brand
Always purchase your car battery from trusted brands that stand behind their products, manufacture durable batteries, and are willing to offer replacements under warranty. Some of the most popular and reliable brands for car batteries are Optima and Odyssey. They provide a reliable service and manufacture safe, secure, and durable batteries for your vehicles.
FAQs

What type of car battery is best for cold weather?

Car batteries with a higher CCA rating as well as reserve capacity are best for cold weather. Generally, AGM batteries tend to perform exceptionally well in chilly environments because they offer better cranking amps and have a low self-discharge rate. And so they provide a robust starting power even during coldest weathers.

What car battery has the most cranking amps?

By now it is a well-established fact that a higher CA rating of battery is better for cold weather. The car batteries with most cold cranking amps are XS POWER D3400 XS Series with a 1000 CCA rating and Odyssey 34M-PC1500ST-M with 880 CCA capacity.

What should be the car battery voltage in cold weather?

A good battery offers a 12.4V or higher at rest. This voltage is ideal for cold weather. Just make sure to keep your battery charged throughout the winter otherwise most of your battery’s ability will be lost during the chills.  

How do I keep my car battery from dying in cold weather?

Cold weather wreaks havoc on car batteries, and we all know that. The best way to keep your car battery from dying is by getting it checked before winter arrives. Try to park your car in a garage or in a warmer temperature. Get your battery a thermal blanket if you can. And most importantly, take it for a daily drive for 20 minutes or longer.
