Installation guide - Replacing a battery

General guidance for this part type - always follow your device manual
Tools
  • Small screwdriver, only if the battery cover is screwed shut
Tips
  • Match the voltage and battery code printed on the old battery.
  • If the device does not power on, reseat the plug before assuming a fault.
  • If the old battery is swollen, do not press, bend or puncture it. Tape over its contacts and take it to a battery recycling point; never put it in household trash.
  1. 1Switch off and unplug. Turn the device off (robot vacuums: switch off the main power switch) and disconnect the charger.
  2. 2Open the battery compartment. Most use a sliding door, a latch, or a cover with two small screws on the underside. Battery packs on tools and vacuums slide out after pressing the release button.
  3. 3Remove the old battery. Lift it out by its tab. If it has a plug, squeeze the plug's latch and pull the plug body, never the wires.
  4. 4Fit the new battery. Place it the same way round, push the plug in until it clicks and make sure the battery sits flat without pinching wires.
  5. 5Close and charge. Refit the cover and charge to full before first use.
