Battery will not latch securely into the vacuum

Safety first: Do not operate the vacuum with a loose battery; it may disconnect under load.

Step-by-step:

• 1. Inspect latch surfaces: Examine the plastic latch on the battery and the catch in the handle for wear, cracks, or deformation.
• 2. Clean latch area: Remove dust and debris from the latch using a dry brush or compressed air.
• 3. Test engagement: Insert the battery firmly until you hear a click. Gently pull to confirm it is locked.

If the latch or catch is damaged and will not hold the battery securely, replace the battery pack or handle assembly as appropriate.
