AJC Battery Compatible with John Deere JS46 Lawn Mower and Tractor Battery

What It Is

The AJC Battery is a direct-replacement sealed lead-acid (SLA) battery for John Deere JS46 walk-behind mowers and select compact riding tractors. It powers the electric starter and provides consistent cranking amps for starting the engine, with no maintenance required.

Fitment & Compatibility

Before buying, verify these three things:

• Model fit: Confirmed for John Deere JS46 push mowers. Also fits some JD riding tractors (e.g., L100, L110, LA105) but always cross-check with your model number.
• Dimensions: 5.9 x 3.4 x 5.1 inches (L x W x H). Measure your battery tray – if it’s smaller or differently shaped, this won’t fit.
• Terminal layout: Uses standard SAE posts (positive left, negative right when facing terminals). If your mower has side terminals or a different orientation, this is not compatible.
• OEM vs aftermarket: This is an aftermarket replacement. It matches OEM specs for cranking amps (typically 230 CCA) but is not a genuine John Deere part.

Key Things to Know

• Quality concerns: 3.8 stars from only 15 reviews is a yellow flag. Some users report shorter lifespan (1-2 seasons) versus OEM or premium brands (3-4 seasons).
• Installation: Simple – remove old battery, clean terminals, connect red to positive, black to negative. No special tools needed.
• Charging: It arrives partially charged. If your mower sits for weeks, use a trickle charger to extend life. This battery is not deep-cycle rated.
• Return policy: Check the seller’s policy before buying. Some aftermarket batteries have strict return windows if damaged during shipping.

Should You Buy It

Buy this if you need a budget-friendly, quick replacement for a JS46 or compatible JD mower and don’t mind replacing it sooner than a premium battery. Skip it if you want a proven, long-lasting battery for heavy use or cold climates – spend a bit more on a known brand like Yuasa or Exide for better reliability and support.
