Shark UltraCyclone CH951 U4 Battery Replacement

Difficulty

Moderate

Steps

Time Required

30 - 45 minutes

Introduction

This guide will provide instruction for how to safely remove and replace the battery in the Shark UltraCyclone CH951 vacuum. The battery holds a 15 minute charge for 6 hours of charging time. If the battery cannot hold a charge for this time or is not charging at all, it may need to be replaced. The battery is connected to the motor, and will need to be removed along with the motor from the vacuum. This is a moderately difficult process.

Note: If there are exposed wires or any defects noticeable, proceed with caution as other issues may cause risk.

Tools

Step 1

Press the dust cup release button and gently pull the dust cup away from the body of the vacuum.

Step 2

Use a TR9 Torx screwdriver to remove the two 8.7 mm screws previously behind the dust cup.

Step 3

Remove the two 12.2 mm screws underneath the dust cup button using a TR9 Torx screwdriver.

Step 4

Remove the 13.9 mm screw beneath the charging port using a TR9 Torx screwdriver.

Step 5

Use the TR9 Torx screwdriver to remove two 11.6 mm screws that hold the exterior motor in place.
They are located underneath where the dust cup previously was and above the exterior motor.

Step 6

Run an iFixit Opening Tool under the casing along the vacuum body until the shell is removed starting around the attachment port, and sliding down towards the charging port.
If necessary, apply gentle force.

Step 7

Press down on the connection point of the white wire and disconnect it.
The connector looks like a white latch. Push down on the edge to pop it out of place.

Step 8

Disconnect the red wire by pressing down and gently pulling the two sides apart.

Step 9

Gently pull on the exterior motor.
There will be wires attached that were previously disconnected and will need to pass through the handle of the vacuum. Complete this step carefully so that no damage is done.
Remove the exterior motor, attached to the interior motor and battery.
