About Product Overview

The DEKA Gold Series 665MF is built for vehicles that need serious cranking power, especially in cold weather. With 850 cold cranking amps at 0 degrees F, it's rated to deliver a strong, reliable start even on the coldest mornings when your engine needs it most.

This is a BCI Group Size 65 battery, a common fit for many trucks and larger vehicles that call for higher output than standard passenger car batteries provide. It's maintenance free and fully sealed, so there's no checking fluid levels or dealing with corrosion from open cells - just install it and let it run.

Made in the USA, the 665MF is a rechargeable 12-volt battery designed to hold up under the demands of daily driving, towing, or work truck use. If your vehicle spec calls for Group 65 with high CCA, this one covers the job without extra frills.

  • BCI Group Size: 65
  • Cold Cranking Amps: 850 at 0°F
  • Voltage: 12V
  • Maintenance free and sealed construction
  • Rechargeable
  • Made in the USA

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
