What It Is

The Caltric AGM Battery is a sealed, maintenance-free 12V power source designed to start ride-on lawn mowers and garden tractors. It replaces OEM MTD batteries (models 925-1707C, 925-1707D, 725-1737, 725-1706A, 725-1707D, 725-1750A) and is suitable for use in MTD, Cub Cadet, Troy-Bilt, and Yard Machines equipment.

Fitment & Compatibility

Before buying, verify these three things:

1. Dimensions – This battery measures approximately 7.7" L x 5.1" W x 6.1" H. Measure your battery tray to ensure it fits. AGM batteries are often slightly taller than standard lead-acid units.
2. Terminal Orientation – Positive terminal is on the left when facing the battery label. Check your cable routing to confirm it matches. Reversing cables can damage electronics.
3. OEM Part Number – The Caltric is a direct replacement for MTD part numbers listed above. Cross-reference your mower’s model number (found under seat or on frame) with MTD’s parts lookup to confirm compatibility. It will not fit zero-turn mowers with different battery specs.

Key Things to Know

• Quality concerns – With a 3.0/5 rating from only 2 reviews, consistency is unknown. Some users report shorter lifespan than OEM or name-brand AGM batteries.
• Installation – Easy: remove old battery, clean terminals, install new unit, and torque connections to 50-70 in-lbs. No electrolyte filling needed.
• Gotcha – AGM batteries require a compatible charger (constant voltage, not a standard automotive charger) to avoid damage. If your mower’s charging system is older, consider upgrading the regulator/rectifier.
• Warranty – Caltric typically offers a 1-year warranty, but check the seller’s return policy. Defective units may require a replacement claim.

Should You Buy It

Buy this Caltric battery if you need an affordable, drop-in replacement for an MTD mower and you’re comfortable with a moderate risk of shorter service life. It’s a decent budget option for occasional use, but for heavy-duty or commercial mowing, invest in a higher-rated brand like Yuasa or Deka for better reliability and longer lifespan.
