Dyson V8 Replacement Battery 21.6V 8000mAh — Filters Included
Condition: Like New. Tested and fully working with minor signs of use. All included accessories (pre-filter, post-filter, screwdriver, screws, and battery terminal cover) present in original poly bags; no visible cosmetic damage on the battery unit.
This Dyson V8 Pro replacement battery delivers a powerful 21.6V output at 8000mAh capacity. It provides 172.8Wh of energy to keep your cordless vacuum running longer. This is a smart, cost-effective upgrade for any V8 owner. The battery snaps directly into your existing Dyson V8 vacuum body. Installation is straightforward with the included screwdriver and hardware.
Like-new condition — no scratches, cracks, or cosmetic wear visible on the housing. The battery body shows clean, glossy plastic on all surfaces. The charge indicator window is intact and unobstructed. Connector contacts are clean and undamaged. This unit presents exceptionally well for a returned item.
The V8 Pro replacement battery is built to match OEM voltage specifications exactly. It runs at 21.6 volts, the same as the original Dyson V8 power pack. The 8000mAh capacity offers extended runtime per charge cycle. This is a significant step up from many aftermarket alternatives. Consistent voltage delivery means strong, stable suction throughout the cleaning session.
This battery uses lithium-ion cell technology for reliable energy storage. Li-Ion chemistry offers a low self-discharge rate between uses. It also supports a high number of charge-discharge cycles before capacity degrades. The battery is RoHS, CE, UKCA, and FCC compliant. Safety certifications confirm it meets international electrical safety standards.
Installation requires only the included Phillips-head screwdriver. The battery latches onto the V8 vacuum handle via the standard Dyson clip mechanism. The terminal cover protects the battery connector during storage or transport. Mounting screws are provided in a sealed poly bag. Everything you need for a full swap is included in this package.
The pre-filter is a cylindrical mesh-style filter in blue. It fits inside the vacuum body ahead of the motor. The post-filter is a round disc-style unit, also in blue. Both filters are sealed in individual poly bags and appear unused. Fresh filters installed alongside a new battery ensure peak airflow and filtration performance.
The battery label confirms the model designation as V8 Pro. Manufacturer information lists Huizhou Rong Hui Technology Co., Ltd. The EC representative is Apex CE Specialists GmbH based in Düsseldorf, Germany. This indicates proper European market compliance. The FCC marking confirms US regulatory compliance as well.
This replacement battery is compatible with the Dyson V8 series of cordless stick vacuums. It is designed to fit models that use the standard V8 battery port. Always confirm your specific model's compatibility before purchase. The V8 lineup includes the V8 Absolute, V8 Animal, and V8 Fluffy variants. For more on lithium-ion battery technology, see the Lithium-ion battery Wikipedia article.
Replacing a worn vacuum battery can dramatically improve cleaning performance. A degraded original battery often cuts runtime to just a few minutes. This high-capacity replacement restores full runtime to your V8 vacuum. It is a far more economical choice than purchasing an entirely new vacuum.

Frequently Asked Questions
Question 1: Is this battery compatible with all Dyson V8 models?
Answer 1: This battery is designed to be compatible with the Dyson V8 series of cordless vacuums. Compatible models typically include the V8 Absolute, V8 Animal, and V8 Fluffy. We always recommend verifying your specific model number against the battery specs before purchasing to ensure a proper fit.
Question 2: What accessories are included with this replacement battery?
Answer 2: This listing includes the battery unit itself along with a full set of accessories. The package contains a pre-filter, a post-filter, a Phillips-head screwdriver, mounting screws, and a battery terminal cover. All accessories were found sealed in their original poly bags, indicating they have not been used.
Question 3: How does 8000mAh compare to the original Dyson V8 battery?
Answer 3: The original Dyson V8 battery is rated at approximately 2,200mAh to 3,000mAh depending on the version. An 8000mAh replacement battery offers substantially higher capacity on paper. Real-world runtime gains depend on cell quality, discharge rates, and how the vacuum's power management system interacts with the pack — results can vary, but many users report noticeably extended cleaning sessions.
Question 4: What safety certifications does this battery carry?
Answer 4: The battery label confirms RoHS, CE, UKCA, and FCC compliance markings. RoHS compliance means it restricts hazardous substances in its construction. CE and UKCA markings indicate conformity with European and UK electrical safety directives, while FCC marking confirms US regulatory compliance for electronic devices.
Question 5: What is the condition of this specific unit?
Answer 5: This unit has been graded like-new with minor signs of use — meaning it was previously owned but shows minimal cosmetic evidence of use. It has been tested and confirmed fully functional. There are no scratches, cracks, or damage visible on the battery housing, and all accessories remain in sealed poly bags.
A high-capacity replacement battery is one of the best investments for a Dyson V8 owner. Keeping a spare charged battery on hand eliminates downtime mid-clean. This vacuum battery is ready to snap in and go with no additional tools beyond the included screwdriver. The V8 platform remains one of the most popular cordless vacuum systems available. Investing in a quality replacement extends the usable life of the entire vacuum.
The included filter set adds additional long-term value to this purchase. Filters are a consumable part of any vacuum system. Fresh filters protect the motor from fine dust and debris. They also maintain strong airflow and suction consistency. Having both a pre-filter and post-filter included means you can refresh the entire filtration system at the same time you install the replacement battery.
This battery is listed in like-new condition and has been physically inspected. The glossy black housing is free of scratches, scuffs, or blemishes. The battery connector pins are clean and properly aligned. The charge indicator LED window is clear and functional. Buyers can purchase with confidence knowing this unit has been carefully checked before listing.
