FAQs
- 1 Locate your vacuum cleaner model number or the part number printed on your original battery, then check whether it appears in the "Compatible vacuum cleaner Models" or "Compatible Battery Part Numbers" section on this page.
- 2 Make sure the voltage of this replacement battery matches the voltage of your original battery.
- 3 Compare the battery shape, connector position, and product images with your existing battery to ensure a correct match.
A:
Cordless vacuum batteries use lithium-ion cells that naturally degrade over time. This is mainly caused by charge cycles, aging, and heat exposure during repeated use.
As the battery wears out, its usable capacity decreases and voltage becomes less stable under load. This leads to shorter runtime, faster power drop in Max mode, and reduced overall cleaning time compared to when the vacuum was new.
Yes, this is a common sign of lithium-ion capacity degradation.A battery can still show a full charge while its actual energy storage capacity has dropped significantly. In this case, the vacuum may run out of power much faster, especially during high-power or Max mode operation.
-
Typical signs include:
- 1 Noticeably reduced runtime per charge.
- 2 More frequent recharging during cleaning.
- 3 Inability to complete a normal cleaning session.
This usually indicates battery wear rather than a charger or vacuum malfunction.
A: Replacing the battery does not increase the vacuum’s original suction power rating, but it can restore stable power delivery. As lithium-ion batteries age, internal resistance increases and voltage may drop more quickly under load. This can cause inconsistent suction, reduced performance in Max mode, or unexpected shutdowns. A new battery helps the vacuum operate with stable power output, restoring normal runtime and consistent cleaning performance.
