Product Description
Built for Trucks That Don't Stop Working
If your Ford F-150 or Ram 1500 has a start-stop system, a regular battery just won't keep up. Every time your engine shuts off at a red light and restarts, it's putting extra demand on your battery — and conventional batteries wear out fast under that kind of cycling.
The Marathon 94R AGM Battery is built specifically for this. It's a true Group 94R fit, so you won't run into terminal placement or hold-down issues during install.
Why AGM Makes the Difference
Absorbed Glass Mat (AGM) technology means the electrolyte is sealed in glass mat separators instead of sloshing around in liquid form. That translates into real advantages for your truck:
- Charges up to 2x faster than a standard flooded battery, so your truck's start-stop system recovers quicker
- Handles roughly 3x more charge cycles before wearing out
- Sealed, spill-proof design with zero free acid — safer to handle and mount
- Performs reliably even when it's not kept at a full charge, which matters for trucks that idle a lot or run heavy accessories
Confident Starts, Even in the Cold
With 850 cold cranking amps, this battery is rated to start your engine reliably even on the coldest mornings. A 140-minute reserve capacity also means if your alternator hiccups or you leave something running, you've got a real cushion before you're stuck calling for a jump.
A Drop-In Fit, No Guesswork
This is a genuine Group 94R battery — same dimensions, terminal layout, and hold-down style your truck came with. No adapters, no modifications, no surprises when you pop the hood.

Frequently Asked Questions
Will this battery fit my Ford F-150 or Ram 1500?
A: Yes — this is a true Group 94R battery, matching the terminal layout and hold-down style used on Ford F-150 and Ram 1500 trucks equipped with this battery group size. Always double-check your owner's manual or current battery's group size before ordering.
What's the difference between "94" and "94R"?
A: The "R" indicates reversed terminal polarity compared to a standard Group 94. Installing the wrong polarity can make cable routing difficult or impossible, so it's important to confirm your truck calls for 94R specifically.
Do I need an AGM battery, or will a standard battery work?
A: If your truck has a start-stop system, AGM is strongly recommended. Standard flooded batteries wear out quickly under the frequent on/off cycling that start-stop systems require, while AGM is built to handle it.
Can this battery be mounted on its side?
A: AGM batteries are sealed and spill-proof, which gives more mounting flexibility than flooded batteries. That said, always follow your vehicle manufacturer's recommended mounting orientation.
How do I know when it's time to replace my battery?
A: Slow cranking, dashboard warning lights, or a battery older than 4-5 years are common signs. If your start-stop system has stopped engaging consistently, a weakening battery is often the cause.
