Dyson V8 Replacement Battery vs Dyson V11 Replacement Battery
Buy the V11 battery only if you own a V11 (SV14) — the two packs are not interchangeable, so the choice is set by your vacuum, not by specs. The V11 pack has more capacity (4200 mAh vs 2800 mAh) and a longer stated warranty (3 years vs 12 months). The V8 pack is the only option for V8 Absolute and Animal owners. No prices were provided for either pack, so compare live store prices on Deal.ai before buying.

Questions and answers
- Can I use the V11 battery in a V8?
- No. The V8 pack is 21.6V and the V11 pack is 25.2V, and the mounts differ. Each fits only its own series.
- Which pack lasts longer per charge?
- The V11 pack has the larger capacity at 4200 mAh versus 2800 mAh. Dyson states 40 minutes of fade-free run time for the V8 pack; no run time is stated for the V11 pack.
- Which has the better warranty?
- The V11 pack lists a 3-year warranty. The V8 pack lists 12 months.
- Is the V11 battery worth the extra cost?
- Only if you own a V11. For a V8, the V11 pack will not fit at any price, so the V8 pack is the only choice.
- Do these batteries have a memory effect?
- The V11 listing states no memory effect, so you do not need to fully discharge it before charging. The V8 listing does not state this.
