MX24V 4.0Ah Battery - Compatible with LawnMaster and Vacmaster 24V/48V Cordless Products 24LB4005-CN

What It Is

The MX24V 4.0Ah Battery (model 24LB4005-CN) is a lithium-ion power pack designed to run cordless LawnMaster and Vacmaster 24V or 48V lawn mowers, trimmers, blowers, and other outdoor power equipment. It provides 4.0 amp-hours of runtime—roughly 30-45 minutes under moderate load—and replaces OEM batteries for these tool systems.

Fitment & Compatibility

• Brands: Directly compatible with all LawnMaster and Vacmaster 24V/48V cordless products. Not cross-compatible with other brands (e.g., Ryobi, Greenworks, DeWalt).
• Model check: Works with any LawnMaster or Vacmaster tool that accepts the standard 24V slide-in battery interface. Common models include LawnMaster LB4005, LB4010, and Vacmaster VB2405.
• Voltage: Single battery works in 24V tools; two batteries in series (sold separately) power 48V machines. Do not mix with different amp-hour or voltage batteries.
• Physical dimensions: Approximately 5.5 x 3.5 x 2.5 inches; weight ~1.2 lbs. Verify your tool’s battery compartment fits these dimensions—especially if you have an older or compact model.
• OEM vs. aftermarket: This is an OEM replacement, not a generic. It matches original specs and charging requirements.

Key Things to Know

• Quality: Rated 4.4/5 stars from 236 reviews—generally reliable, but some users report shorter lifespan (1-2 seasons) under heavy use. Not as durable as premium brands like Makita or Milwaukee.
• Installation difficulty: Trivial—slide onto tool until latch clicks. No tools required. Ensure terminals are clean and dry before connecting.
• Charging: Use only the original LawnMaster/Vacmaster charger (24V, 2A recommended). Overcharging or using a 48V charger can damage the battery or cause fire risk.
• Storage gotcha: Store at 40-80°F for best lifespan. If left discharged for months, it may fail to hold a charge. Recharge every 60 days during off-season.

Should You Buy It

Buy this if you need a direct, OEM-replacement battery for your LawnMaster or Vacmaster 24V/48V tools and want a reliable, drop-in fix without modifying connectors. It’s a solid choice for homeowners with moderate lawn size, but if you mow an acre or more, consider a higher-capacity (5.0Ah or 6.0Ah) option for longer runtime.
