YARDCARE 4.0 Ah Li-ion Battery, 18-Volt, 72W, Replacement Battery, Applicable to All Products, B1804002

What It Is

The YARDCARE B1804002 is a 4.0 Ah, 18-volt lithium-ion replacement battery (72Wh) designed to power cordless lawn mowers, trimmers, blowers, and other outdoor power equipment from the YARDCARE brand. It’s a drop-in replacement for the original battery that came with your tool.

Fitment & Compatibility

• Brand & Model: This battery is labeled “Applicable to All Products” but is specifically intended for YARDCARE 18V tools. It is not cross-compatible with other brands (e.g., Ryobi, Black+Decker, Greenworks) due to different voltage, shape, and terminal layouts.
• Check Your Tool’s Voltage: Ensure your mower or tool is 18V (not 20V or 40V). The battery is 18V nominal (20V max).
• Physical Fit: Measure your existing battery compartment. The B1804002 dimensions are approximately 5.5 x 3.5 x 2.5 inches. If your original battery is larger or has a different slide/click mount, it won’t fit.
• OEM vs Aftermarket: This is a YARDCARE-branded replacement, not an OEM (original equipment manufacturer) battery from your tool’s maker. It’s a third-party alternative, so verify your tool’s battery model number ends in B1804002 or similar.

Key Things to Know

• Installation: Trivial – slide the battery onto the tool’s base until it clicks. No tools or wiring needed.
• Quality & Performance: 4.0 Ah capacity gives decent runtime (about 30-45 minutes on a typical 18V mower), but 7 reviews suggest mixed long-term reliability. Some users report shorter life after a few months.
• Charging: Uses a standard YARDCARE 18V charger (sold separately). Do not mix with other brands’ chargers – voltage or pinout differences can damage the battery or charger.
• Gotcha: “Applicable to All Products” is misleading – it only fits YARDCARE 18V tools. If you have a different brand or voltage, skip this battery.

Should You Buy It

Buy this if you own a YARDCARE 18V lawn mower or trimmer and need a spare or replacement battery at a lower cost than OEM. It’s a decent budget option for light-to-moderate use, but if you rely on heavy mowing or want maximum longevity, consider an OEM battery instead.
