Safety first: Turn OFF the vacuum before removing the battery.

Step 1 – Confirm full charge: Charge the battery until the charger indicates 100%.
Step 2 – Measure runtime: Use the vacuum continuously in standard mode and time how long it runs from full to automatic shutoff.
Step 3 – Compare to spec: Compare your measured runtime to the original Essentials specification. If it is less than 50–60% of rated time, the battery is likely worn.
Step 4 – Replace battery: Purchase and install a genuine Essentials replacement battery pack.

Warning: Do not continue using a battery that becomes very hot or swells; replace it immediately.

Vacuum runtime is significantly shorter than when new, even after a full charge.
