What you get, by the numbers
48V 2.4Ah lithium battery with charger adapter
2.4Ah lithium-ion cell, Makita-compatible socket, fast-charging adapter included — $24.99 complete kit.
Steady power, no fade
The 2.4Ah lithium-ion cell holds its output instead of dropping off mid-job, so you can wash a vehicle, rinse the patio, and wipe down outdoor furniture in one pass without stopping to recharge.
Fits Makita-style tools
The sliding socket is built for Makita-compatible interfaces, so the battery seats firmly in your high-pressure washer and other yard tools with no rattle or loose contact.
Fast charger in the box
A dedicated quick-charge adapter is included, so you can top up and get back to work without buying a separate charger.
Three-way safety protection
Built-in safeguards guard against overcharging, overheating, and short circuits, which helps extend the battery's service life and keeps every charge cycle safe.
One battery isn't enough. Two keep you working.
At $24.99 each, add a second 2.4Ah battery and charger so cleaning and yard work never wait.
Wash the car without a recharge pause
With one battery in the washer and one charged as backup, you can finish wheels, panels, and rinse without stopping to wait for power.
Clean patios and outdoor furniture
Spray down tabletops, chairs, and patio floors in one pass. The 2.4Ah lithium-ion cell keeps power steady while a spare stays ready.
Keep yard tools running
The Makita-compatible sliding socket locks into your high-pressure washer and compatible yard tools, so you can move from task to task without downtime.
Rotate spare batteries and keep going
Charge one battery with the included adapter while the other powers your tool. Swap packs and stay on schedule instead of waiting on a single battery.

Common questions, answered before you buy
Is this a genuine Makita battery or a third-party compatible product?
This is a third-party lithium-ion battery built with a Makita-compatible sliding socket. It is not manufactured or sold by Makita. The interface is designed to fit tools and chargers that use the Makita sliding-socket system.
What voltage is the battery?
The battery provides an 18.5V nominal voltage and up to 21V maximum output, with a 2.4Ah (2400mAh) capacity. It is fully compatible with standard 18V–21V cordless tools. Please note: Current units feature a "48V" series label on the shell, while new batches are being updated to 21V Max labeling.
Which tools and models does it fit?
It fits products that accept a Makita-compatible sliding socket, including the high-pressure washer it is bundled with. Exact model numbers are not listed by the supplier, so please check your tool's socket type and voltage before purchase. If you are unsure, contact us with your model and we will confirm.
How long does one charge last?
Runtime depends on the tool and how hard you push it. The 2.4Ah cell is built to hold steady output for jobs like washing a vehicle, patio, or outdoor furniture without fading partway through. For heavy, continuous use, keep a second pack on hand.
How long does charging take?
The included charger adapter is a fast-charging type, but the supplier does not publish an exact charge time. As a practical guide, expect a shorter top-up cycle than a standard charger on the same pack. Charge the battery fully before first use.
What safety features are built in?
The pack includes protection against overcharging, overheating, and short circuits. These safeguards help extend battery life and keep operation stable during repeated charge and discharge cycles.
What is the warranty and return policy?
Warranty length and the return window are set by the store and confirmed at checkout. If the battery arrives damaged, faulty, or does not fit your compatible tool, contact us within the stated return period for a replacement or refund. Keep the packaging until you have tested the fit.
