Meet the BatteryMate's Signature Smart Series battery for your Dyson DC31 (Type B). Most batteries on the market simply store power. This one has an advanced BMS and newer-technology battery cells, so it charges fast and runs longer, clean after clean.
Signature Smart Series highlights
- Longer runtime - Adaptive Power Delivery gives the motor what the job needs and eases off when it doesn't, while Idle Preservation holds charge between cleans instead of wasting it on the wall.
- High-capacity Grade A cells - Active Heat Management sheds heat faster after heavy use, so less energy is lost as warmth and the cells stay healthier for longer.
- Fast charging on your original Dyson charger
- Built-in protection against overcharge, over-discharge, over-current, over-voltage and short circuit.

FAQs
Q: What makes this a BatteryMate's Signature Smart Series battery?
A: A built-in management circuit controls how power is delivered, holds charge when idle, manages heat and protects the cells. Standard replacement batteries typically have basic protection only.
Q: Will it run longer, and how long does a charge last?
A: Yes. High-capacity cells plus Adaptive Power Delivery outlast a standard replacement and far outlast a worn original. Exact runtime depends on the power mode and attachment you use.
Q: Does it work with my original Dyson charger?
A: Yes. It fast charges on your original Dyson DC31 (Type B) charger, so there is nothing extra to buy.
Q: Is this a genuine Dyson battery, and is it covered by warranty?
A: No. It is a Tavice-made compatible replacement, not made or endorsed by Dyson, and is backed by our Australian warranty and local support.
Q: How do I know if my Dyson needs a Type A or Type B battery?
A: Check the label on your existing battery pack. Type A packs are held in with a release button, while Type B packs are screw-in. The model code alone doesn't tell you, so please match the type before ordering.
