Interstate MTP-24F Battery vs Duracell Ultra U1 Lawn & Garden Battery

These are not really rivals. The Interstate MTP-24F is a full-size Group 24F car battery with 750 cold cranking amps and 120 minutes of reserve capacity, built for starting a vehicle in cold to moderate climates. The Duracell here is a small U1 lawn-and-garden battery rated at 350 CCA, sized for mowers, garden tractors and lift stands. For a car that takes a 24F, buy the Interstate. For a mower or small equipment, buy the Duracell. Owners rate the Interstate well on starting power and the 30-month free replacement; the Duracell's 3.1 out of 5 from 11 ratings is thin and mixed.

  • Choose the Interstate MTP-24F if you need a Group 24F car battery with strong cold-cranking power and a 30-month free replacement warranty.
  • Choose the Duracell U1 if you are replacing the battery in a lawn mower, garden tractor or electric lift stand that takes a small U1 case.

What reviewers say

Interstate MTP-24F Battery

Owner feedback on Interstate's flooded MTP line is generally positive, with buyers citing reliable starts and long service life. Complaints tend to center on batteries failing inside the warranty period and on the hassle of getting a replacement honored.

What people mention
  • Cold startingPraisedOwners say it cranks strongly on freezing mornings.
  • LongevityMixedMany get four or more years, but some report early failures.
  • WarrantyMixedThe 30-month free replacement is valued, though claims can be slow to process.
  • MaintenanceCriticisedFlooded cells need occasional water checks that owners find easy to neglect.

Duracell Ultra U1 Lawn & Garden Battery

  • 3.1 / 511 ratings

Feedback is split. Some owners say it starts their mower reliably and fits as expected, while others report it failing within a season or two.

What people mention
  • LifespanCriticisedSeveral owners say the battery died after a season or two of mower use.
  • Starting powerMixedIt cranks small engines fine when new, but some report sluggish starts in cold weather.
  • FitPraisedBuyers say the U1 size drops into standard mower and lift-stand trays.

Questions and answers

Will the Duracell U1 work in my car?
No. At 350 CCA and U1 size it is meant for small engines. A car that calls for a 24F needs the Interstate's 750 CCA and larger case.
Is the Interstate MTP-24F an AGM battery?
No. It is a flooded lead-acid battery. If your car requires AGM, such as many start-stop vehicles, choose an AGM instead.
Which lasts longer?
The Interstate carries a 30-month free replacement and a 6-year performance rating. The Duracell listing states no warranty, so the Interstate is the safer bet on longevity.
Can I use the Interstate for a lawn mower?
It would physically fit some large riders, but it is oversized and overkill. The Duracell U1 is the right size for most mowers and garden tractors.
Is the Duracell worth stepping up to?
There is no step up between these two; they serve different vehicles. Pick by what the equipment requires, not by brand.
