Q: I can buy an inexpensive battery at my local big-box store. Why not do this?
A: Battery quality between manufacturers and brands can vary widely. Of course, you get what you pay for.

Cheaper batteries may contain less lead, have a thinner or weaker case, or have less substantial bridging bars between the plates. It's been our experience that less expensive batteries do not provide reliable service over the long haul.

The batteries we recommend have a life expectancy of at least 5 years (typically 6 years or more.) Our criterion is that a good quality 4.5-year-old battery should start your car reliably in -30 Deg. F. conditions.

Q: Should I buy a battery with the highest CCA rating?
A: No. It is very easy for low-cost battery manufacturers to inflate this number at the expense of battery life.

You should purchase a battery that meets the size and capacity specifications published by the vehicle's manufacturer, with the strongest and longest life warranty. Our best batteries have an 85-month warranty.
