3.5Ah Battery for Briggs & Stratton 82V and Snapper 82V Cordless Tools Lithium-ion Rechargeable Battery Model BSB2AH82 BSB3AH82 BSB4AH82 BSB5AH82 Replacement

What It Is

This is a 3.5Ah lithium-ion battery designed to power 82V cordless lawn mowers, trimmers, blowers, and other tools from Briggs & Stratton and Snapper. It replaces OEM models BSB2AH82, BSB3AH82, BSB4AH82, and BSB5AH82, offering a mid-range runtime for residential yard work.

Fitment & Compatibility

Before buying, verify your tool is 82V (not 40V or 60V) and from Briggs & Stratton or Snapper. This battery fits all 82V cordless tools from these brands, including mowers (e.g., Snapper 82V SP, Briggs & Stratton 82V 21-inch) and handheld equipment. Check the battery slot shape—it uses a slide-in mount common to these lines. It is a direct replacement for OEM models ending in AH82; if your original battery has a different model number (e.g., BSB6AH82), measure the dimensions (approx. 6 x 4 x 3 inches) to ensure it fits your tool’s compartment. Not compatible with 40V or 60V systems.

Key Things to Know

• Quality: Rated 4.1/5 (9 reviews)—generally reliable but limited feedback may hide long-term issues. Expect 30-45 minutes runtime on a mower with average grass.
• Installation: No tools needed; slide into tool’s battery port until it clicks. Ensure contacts are clean before inserting.
• Gotcha: This is a non-OEM replacement—may have slightly shorter lifespan or lower power output than original Briggs & Stratton batteries. Check charger compatibility (uses standard 82V charger).
• Warranty: Usually 1 year from Snapper; confirm before purchase.

Should You Buy It

Buy this if you need a budget-friendly spare or replacement for a Briggs & Stratton or Snapper 82V tool, and you don’t require maximum runtime for large lawns. It’s a solid choice for light-to-moderate use, but if you need heavy-duty performance or long-term reliability, consider an OEM battery with more reviews.
