Just as described

Have not used it yet but it charged up quick. Looks just like the one that came with the vac.

Can't charge on my A10 Hero

Was excited to order a larger capacity battery. It fit my A10 Hero but since there is no charge port I didn't have a way to charge this battery.

It didn’t fit! the correct battery.

I have written 2 emails asking Tineco if I can get the correct battery. There has been no response.
I do not recommend doing business with this company.

Great customer service

I ordered the wrong battery it did not have a hole to plug charger in like my orginal although the it was identical in size. I should have cotacted customer service first. They let me send back wrong battery and sent the correct one without any additional charges-thanks for fixing my mistake.

Great batteries

We purchased our Tineco vacuum over 3 1/2 years ago and just now we noticed they were not lasting as long as they used to (we’re talking about being used daily and continuously in a house close to 3,000 sq feet. That’s why we purchased an additional one which brought our vacuum back to new again. Tineco is impressive!
