Dyson DC45 replacement battery FAQ
How can I tell if my Dyson DC45 battery needs replacing?
Common signs include reduced runtime, sudden shut-offs, charging failures or flashing LED indicators. If you notice these, it’s probably time to buy a replacement.
How do I replace the battery in my Dyson DC45?
Switch the vacuum off, remove the two screws (one on the handle, one on the underside), take out the old battery, slot in the new one and screw it back into place. Always fully charge before first use.
Why does my Dyson DC45 battery run down so quickly?
Over time, all rechargeable batteries lose capacity. After 2–4 years, many DC45 batteries cannot hold enough charge, leading to shorter runtimes. The best fix is replacing it with a higher-capacity battery for longer cleaning sessions.
To maximise battery life: recharge your battery before it drops below 20% power and store it at around 40% if unused for long periods.
Which battery fits my Dyson DC45?
First, check whether your vacuum uses a Type A or Type B battery, and confirm the model number and voltage (usually 22.2–22.8V) match the replacement.
