CUB CADET 725-04903 Battery 12V SC EZ EQ EQ E CC600 CC 700 600 500EZ 500E 500

What It Is

This is a 12V sealed lead-acid (SLA) battery designed to power electric-start engines on Cub Cadet riding mowers and zero-turn mowers. It’s a direct replacement for the original battery in models like the CC 600, CC 700, EZ EQ, EZ, and 500-series (500EZ, 500E, 500).

Fitment & Compatibility

Before buying, confirm your mower’s model number and that the battery compartment dimensions match: roughly 5.9" L x 3.5" W x 5.0" H. This battery fits Cub Cadet CC 600, CC 700, EZ EQ, EZ, and 500-series tractors (including 500EZ, 500E, and 500). It also replaces OEM part 725-04903 and cross-references to many aftermarket batteries (e.g., U1-7, U1L, UB12120). Check your owner’s manual or remove the old battery to verify terminal orientation (positive on left or right) and that the hold-down bracket aligns. Not compatible with larger frame mowers (e.g., XT1, XT2) without verifying dimensions.

Key Things to Know

• Quality: OEM Cub Cadet battery – reliable cranking power for seasonal use, but not a deep-cycle battery. Expect 3–5 years with proper charging.
• Installation: Simple swap – disconnect negative first, then positive, remove hold-down, replace in reverse order. No special tools needed beyond a 10mm wrench.
• Common Gotcha: This battery comes dry-charged; you must add the included electrolyte acid (sold separately in some kits) and charge it before first use. If you buy a pre-filled version, skip that step.
• Storage: SLA batteries self-discharge over winter. Use a trickle charger/maintainer to extend life – don’t let it sit dead.

Should You Buy It

If you need a direct, no-guesswork replacement for your Cub Cadet CC 600, CC 700, or 500-series mower and want OEM reliability at a fair price, this battery is a solid choice. For older or non-Cub Cadet mowers, measure first – otherwise, it’s a simple, reliable drop-in.
