Tineco Pure ONE S11 Smart Cordless Vacuum Cleaner Replacement Battery, Model S10WM-01, Battery Type 22.2V DC 2500 mAh 55.5Wh (not Compatible with Any Other Model)

The label on the battery states it is for the S10 vacuum and does not fit the S11 vacuum. Also, the output voltage for this battery is 22.2V while the S11 battery is 21.8V. I had to contact Tineco customer service to special order the S11 battery.

Exact duplicate of battery that came with Tineco. Needed two since there is a large area needing vacuuming.

Not sure why I didn’t listen to the other reviews - this does not fit the S11. My vacuum is also on warranty - but no response to my email re the dead battery.

Awesome replacement battery!

It's not for an S11. It's for an S10. Won't attach to the S11

this does NOT fit the Tineco S11.

Why did you pick this product vs others?: I purchased this battery as a replacement. I decided to purchase a new battery so I could contnue to use my stick vac which worked great for about a month and then slowly degraded over time until it was no longer picking up most floor debris. My stick vaccum battery still charged but was weak and made the vaccum useless so I thought a new battery would do the trick and bring the vaccum back to usefulness. NO this battery is just as weak as the one I already have, now I have 2 batteries and a worthless vaccum.

Does not fit the vacuum as advertised.
