725P17136 Battery AGM 7AHR CC 30 H Hydro Mini Rider, Replacement for CUB CADET OEM 

What It Is

The 725P17136 is a sealed AGM (Absorbent Glass Mat) battery rated at 7 amp-hours and 30 cold cranking amps. It is designed specifically for Cub Cadet Hydro Mini Rider lawn tractors, providing reliable starting power and deep-cycle reserve for electric PTO and accessory loads.

Fitment & Compatibility

This battery is a direct replacement for the original Cub Cadet OEM part number 725P17136. Before buying, confirm your machine is a Hydro Mini Rider model (e.g., 13APA1CT056, 13AQA1CT056). Check the battery tray dimensions: this unit measures approximately 5.9" L x 3.4" W x 4.1" H. It will not fit larger Cub Cadet models using a standard U1 or Group 22NF battery. Verify terminal orientation (positive on left when facing the terminals) and that your existing hold-down bracket and cables align. This is a direct-fit OEM replacement; aftermarket equivalents may have different terminal layouts.

Key Things to Know

• AGM vs. flooded: AGM is spill-proof and vibration-resistant, ideal for mowers with slopes or rough terrain. No maintenance (no water filling) required.
• CCA rating: 30 CCA is sufficient for small single-cylinder engines in Hydro Mini Riders. Do not use on larger twin-cylinder models – it will struggle in cold starts.
• Installation difficulty: Very easy – disconnect negative first, swap, reconnect. Takes 10 minutes with basic hand tools. No programming or charging needed if battery is fresh.
• Common gotcha: The battery is pre-charged but may need a slow charge (1-2 amps) if it has been sitting on a shelf for more than 6 months. Use a compatible AGM charger only.

Should You Buy It

If you own a Cub Cadet Hydro Mini Rider and want a no-hassle, direct-fit battery that matches OEM specs exactly, this is the right choice. It’s ideal for users who prefer sealed maintenance-free batteries and value guaranteed compatibility over saving a few dollars with an aftermarket substitute. For other Cub Cadet models or riders with larger engines, look for a higher CCA battery.
