CYDZ® Replacement 12V Battery BL1041B BL1021B,12V 4.0Ah, Charger Replace for DC10WD, for 12 Volt Battery and Charger CXT Series

What It Is

This is a CYDZ® replacement 12V 4.0Ah lithium-ion battery and charger set, designed to power cordless lawn mowers, trimmers, and other outdoor power equipment that use the CXT series battery platform. It’s a direct replacement for the DC10WD mower and compatible with 12V CXT tools.

Fitment & Compatibility

Before buying, confirm your equipment uses a 12V CXT-style battery (not 18V or 40V). This set replaces OEM models BL1041B and BL1021B – check your battery’s label for those numbers. Works with the DC10WD mower and any CXT-series 12V tool (e.g., string trimmers, blowers). Measure your battery compartment: the 4.0Ah unit is slightly taller than a standard 2.0Ah, so ensure clearance. Not compatible with 18V LXT or 40V XGT platforms.

Key Things to Know

• Quality: Aftermarket, not OEM. Users report consistent runtime and reliable charging, but build quality may feel less robust than genuine Makita.
• Installation: Simple – remove old battery, slide in new one. The charger plugs into a standard wall outlet. No tools needed.
• Gotcha: The charger included is a basic model; it may charge slower than OEM. Also, the 4.0Ah capacity gives longer run time but adds weight.
• Warranty: Check seller policy – some aftermarket batteries have limited or no warranty compared to OEM.

Should You Buy It

If you own a DC10WD mower or CXT 12V tool and want a cost-effective replacement for a worn-out OEM battery, this is a solid option. It’s best for light-to-medium yard work where runtime matters but you don’t need premium build or fast charging. Skip it if you require OEM reliability or have a 18V/40V system.
