Kirkland Signature Car Battery
Surprisingly enough, Costco’s in-house brand Kirkland Signature makes one of the best value car batteries to be found on sale today. The performance and amp ratings of the Kirkland Signature car batteries match or exceed that of super-premium brands such as Optima, at about half the price of what you’d pay for the name-brand product. The cold-weather performance of the Costco’ batteries is outstanding, and you can count on your car to start every time even in below-freezing conditions. The Kirkland Signature battery also carries a unique warranty in that it is not pro-rated, meaning you get a full refund of the purchase price if the battery fails for whatever reason. Given its price and the surprising amount of performance and dependability you get from the Kirkland Signature car battery, it is an absolute bargain.
