Tornado Tempest Battery Release Spring K63301600

The Tornado Tempest battery release spring (part# K63301600) is the return spring behind the battery release button (part# K53242030) on the TV400-W26-U cordless sweeper. Tacony lists it as Spring, Battery Release. It is a different part from the battery latch spring (part# K63302640), and the two are not interchangeable.

Its function is simple and easy to underrate: it pushes the button back out after a release, which is what allows the latch to re-engage. If it fails, the button stays pressed, the latch stays retracted, and the pack is held in by nothing but friction. The machine will run — right up until the pack shifts over a threshold and the contacts break.

Compatible Models for the Battery Release Spring

• Tornado Tempest Wide-Area Cordless Carpet Vacuum Sweeper — Model TV400-W26-U

Symptoms that point to the release spring

• The release button stays in after being pressed instead of springing back.
• The pack can be lifted out without pressing anything.
• The button returns slowly or only part way.
• A new release button was fitted and still sticks.
• The spring is visibly collapsed, kinked or broken.

A pack that lifts out without pressing the button is the symptom to act on quickly. At that point nothing is retaining the battery except the fit of the housing, and a 36V pack coming loose mid-pass is both a reliability and a safety problem.

Fitting notes

Remove the battery pack before starting. The spring sits behind the release button in the battery mount (part# K50321850). It is under compression and will spring clear if released carelessly, so work over a tray. Do not substitute the latch spring (part# K63302640) — it is a different rate and length, and fitting the wrong one gives either a button that will not return or a latch that will not hold. After fitting, check the button springs fully back and the latch re-engages before closing up.

Frequently Asked Questions

What does the battery release spring do on the Tornado Tempest?

It pushes the battery release button back out after a release, which lets the battery latch re-engage. Without it the latch stays withdrawn and the pack is not positively retained.

How do I know if my battery release spring needs replacing?

The button staying pressed in, returning slowly or only part way, or the pack lifting out without pressing anything at all. If a new release button still sticks, the spring is the cause.

What models is the battery release spring (part# K63301600) compatible with?

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper. PartSmart lists it against the Tempest alone.

Can I use the battery latch spring instead?

No. The latch spring (part# K63302640) is a different part with a different rate and length. Fitted here it will either fail to return the button or fail to hold the latch — order part# K63301600 for the release.
