Across the board, DieHard Gold car batteries rate well. This line of batteries receives high scores for its reserve capacity -- which measures the battery's ability to provide power when not being recharged -- and its CCA, according to a trusted consumer organization. User reviews tend to agree: The DieHard Gold gets an overall 4 out of 5 star score on, and the majority of users at recommend them.

Long life expectancy is another positive. The DieHard Gold battery carries a 100-month pro-rated replacement warranty, but there are many reports of user's batteries lasting as long as 12 years. "Best and longest lasting battery on the market," say one user. Another reviewer, who reports an 11-year lifespan on an 8-year battery, advises good maintenance habits to get the most of your DieHard battery.

The warranty also includes a 36-month free-replacement policy. A few users mention less impressive life spans, with one noting that they get "no more than average" from the Gold series. Reports of batteries failing in less than three years exist for all brands of batteries, though DieHard Gold seems to have fewer such complaints than others. Owners express satisfaction with the knowledge and level of service displayed by staff at Sears auto centers, where Die Hard batteries are bought and installed.

Low temperatures do more than make icy roads and snowy commutes a hassle. A cold engine, with its thick oil, requires more power to crank. At the same time, the low temps reduce a car battery's capacity by as much as 60 percent, and that can leave you without enough power to turn over your engine. It's very trying to have to jump start your car after freezing temperatures leave you with a dead battery.

For cold-weather climates, it is essential to consider a battery with a high CCA. This number is a measure of how much power your battery can produce at 0 degrees Fahrenheit. The higher the number, the more energy your battery will have to turn a cold, stiff engine over.

User comments suggest that in addition to being a good-quality overall battery, the DieHard Gold is also ideal for use in cars subjected to freezing temperatures. A self-described "value conscious car owner" calls the north version of the DieHard Gold a great value and adds, "My last diehard battery lasted for 6+ years!"

One member of the community reports getting eight years from a DieHard Gold north battery, saying the "old one never failed, it just wore down." A list of the best batteries for extreme cold, put together by a consumer organization known for its independence and credibility includes three northern versions of the DieHard Gold.

The budget-friendly EverStart Maxx-65N, available at Walmart automotive centers, is a good budget alternative The listed CCA of 850 amps almost matches the output of the DieHard Gold 50665, which is rated at 880 CCA, but the EverStart Maxx has inferior warranty coverage. Both brands replace the battery for free for up to 36 months, but DieHard Gold adds on a prorated warranty period of 100 months.

Note that Sears has announced the closing of 80 Sears and Kmart stores, which could have an impact on a DieHard battery owner's ability to get convenient local warranty service.
