Questions and answers
- Will the V11 battery fit my V7 vacuum?
- No. The V11 pack is built for V11 Absolute and SV14 models at 25.2 V. A V7 needs the 21.6 V V7 pack.
- Which gives longer runtime?
- The V11 pack, at 4200 mAh versus 2500 mAh for the V7 pack. Actual runtime also depends on the vacuum's power mode.
- Is the V11 battery worth the extra cost?
- If you own a V11, it is the only one of the two that fits, so the choice is made for you. Compare live prices across stores on Deal.ai before buying.
- How long do these batteries last?
- The V11 listing cites a 3-year lifespan with a 1-year warranty. The V7 listing states no lifespan or warranty, so expect typical Li-ion degradation over a few years of regular use.
- Do I need to fully drain the battery before charging?
- No. The V11 pack is listed as having no memory effect, and Li-ion cells in general do better with partial charges than deep discharges.
