Replacement lithium polymer battery for LG Cord Zero A9 series vacuums, 2000mAh 51.10Wh with decoded chip and safety protections

  • Battery TypeLithium Polymer
  • Replacement for LG Cord Zero A9 series vacuums
  • 2000mAh 51.10Wh lithium polymer capacity
  • 55V voltage matches original specification
  • Fully decoded chip works like the original
  • Overcharge, over-discharge, over-voltage and short-circuit protection

Compatible LG CordZero A9 models

This replacement lithium-polymer battery fits LG CordZero A9, A9 Plus and A9+ stick vacuums. It matches the original part dimensions of 100.52 x 57.86 x 93.36 mm and weighs 449.4 g. The integrated decoder chip communicates with the vacuum electronics exactly like the factory pack.

Sustained runtime and protection

Rated at 2000 mAh and 51.10 Wh, the pack delivers consistent power across a full cleaning cycle instead of fading after a short burst. Built-in circuitry guards against overcharge, over-discharge, over-voltage and short circuits, preserving cell health during repeated daily use.

Temperature and charging limits

Cells must not be stored above 60 °C (140 °F) and should never be charged with a low-quality third-party adapter. Performance peaks after two or three complete charge-discharge cycles, and the connector must be fully seated before operation.
