If your Dyson SV04 isn’t holding a charge like it used to, it’s often a clear sign the battery is wearing out. You might notice the vacuum running for just a few minutes before shutting off. Another indicator is the light flashing red or not charging fully, even after hours plugged in. Reduced suction power and frequent overheating are also common warning signs. A swollen or warm battery after charging signals it’s time for a replacement. Using an aging battery can strain your vacuum motor. Replacing your Dyson SV04 battery restores cleaning power and extends your vacuum’s life.
