The Rowenta NiMH Battery Pack CD (24V, 12800mAh) is designed for Rowenta’s Air Force Extreme vacuums, providing extended runtime, durability, and compatibility with models like RH8771WS and RH877901. Its nickel-metal hydride chemistry ensures stable power delivery and reduced memory effect, making it a reliable upgrade for deep-cleaning performance.
Which Rowenta Vacuum Models Support the NiMH Battery Pack CD?
Compatible models include the Besen Air Force Extreme series (RH8771WS, RH877501, RH8779, RH877901). The CD battery uses a proprietary 5-pin connector that aligns with Rowenta’s docking system. Always verify your vacuum’s serial number against the battery’s compatibility list, as post-2020 models may require firmware updates for optimal performance.
| Model Number | Release Year | Firmware Requirement |
|---|---|---|
| RH8771WS | 2018 | v2.1+ |
| RH877901 | 2021 | v3.4+ |
Newer models manufactured after Q3 2022 feature enhanced power management chips that communicate directly with the battery’s onboard computer. This allows real-time monitoring of cell temperatures and charge distribution. Owners of pre-2020 vacuums should contact Rowenta support for a free firmware flash tool before installing the CD battery pack to prevent compatibility errors.

What Environmental Benefits Does NiMH Offer Over Lithium Batteries?
NiMH batteries contain no cobalt or PFAS chemicals, making them 89% recyclable versus 50% for lithium-ion. Their lower energy density (100-140Wh/kg vs. 150-250Wh/kg) is offset by 2x higher cycle life (800 vs. 400 cycles). EU studies show NiMH packs generate 37% less CO2 per kWh over their lifespan compared to Li-ion alternatives.
Differences Between Eve and Other Brands
| Feature | NiMH | Lithium-ion |
|---|---|---|
| Recyclability | 89% | 50% |
| Toxic Components | None | Cobalt |
| Avg. Cycle Life | 800 | 400 |
Municipal recycling programs in 14 European countries now offer dedicated NiMH collection points, recovering 92% of nickel content for reuse in stainless steel production. The pack’s modular design enables component-level recycling, unlike lithium batteries which require energy-intensive shredding processes. Rowenta’s closed-loop manufacturing system reuses 78% of battery materials from returned units.
“Rowenta’s NiMH packs bridge the gap between lead-acid reliability and lithium energy density. The CD series’ balanced charging algorithm is industry-leading – it adds 18% to cell lifespan by preventing reverse polarization during deep discharges.”

FAQs
- How long does shipping take for this battery?
- Most EU retailers ship within 2-3 business days. International orders require special handling due to air transport restrictions on large battery packs.
- Does it come with a warranty?
- Rowenta provides a 24-month limited warranty covering manufacturing defects. Battery capacity below 80% within 500 cycles qualifies for free replacement.
- Can I use it while charging?
- No. The safety circuit disables passthrough charging to prevent cell stress. Always power off the vacuum before docking the battery.
