A new life for my ilife A9s

Elbotics provided excellent support even before the product arrived, ensuring compatibility with my vacuum cleaner. The battery has revived my A9s, which was unused for over a year due to a lack of replacement options. It now runs like it did when new. Even their batteries is also long-lasting. Thank you, Elbotics.

I needed a replacement battery for my Eufy 11s, and this one worked well. The run time is decent, though recharging takes a bit longer. Initially, I had issues with the wire length being shorter than the original. However, after six months, when the battery showed signs of wear, the seller replaced it promptly. Great customer service by Elbotics
