What It Is

This is a 12-volt, 210-CCA AGM (Absorbed Glass Mat) battery designed for Cub Cadet riding mowers, zero-turn mowers, and tractors that require a compact, maintenance-free power source. It replaces OEM part numbers 725P17335, 925-17335, and 725-17335.

Fitment & Compatibility

Before buying, check the following:

• Dimensions: The battery measures approximately 5.9" L x 4.0" W x 5.7" H (including terminals). Ensure your battery tray can accommodate these exact measurements.
• Terminal orientation: It uses standard SAE posts (top terminals). Verify your cable routing and clearance around the posts.
• CCA rating: 210 CCA is typical for most Cub Cadet residential mowers with single-cylinder engines. For larger twin-cylinder engines, confirm your original battery CCA (some require 230+).
• Cross-reference: Compatible with Cub Cadet models using ZTXS6, ZTXS5, ZTXS4, or ZTX6 group sizes. Also fits many John Deere, Husqvarna, and MTD models using the same form factor—check your owner’s manual or existing battery label.
• OEM vs aftermarket: This is a genuine Cub Cadet OEM part, not a generic replacement. It matches factory specs exactly.

Key Things to Know

• AGM vs flooded: AGM is spill-proof, vibration-resistant, and lasts longer than standard lead-acid batteries. No water refill needed.
• Installation difficulty: Easy—disconnect negative cable first, swap battery, reconnect positive then negative. No special tools required beyond a 10mm or 13mm wrench.
• Shelf life: AGM batteries self-discharge about 3% per month. If storing over winter, use a battery maintainer (not a standard charger) to prevent sulfation.
• Gotcha: Some Cub Cadet models have a small hold-down bracket that may not fit if the battery case is slightly taller than your old one. Measure your tray height before buying.

Should You Buy It

Buy this if you need a direct OEM replacement for a Cub Cadet mower with the ZTXS6/ZTXS5/ZTXS4/ZTX6 footprint and 210 CCA rating. It’s a solid choice for riders, zero-turns, and tractors where reliability and maintenance-free operation matter. Skip it if your mower requires a higher CCA or a physically smaller battery (e.g., lawn tractors with tight battery boxes).
