so, i bought this replacement battery for my xiaomi vacuum after the old one gave out, and honestly, it's a mixed bag. why did i get it? well, i'm a pragmatist—i wanted something reliable without breaking the bank, and this seemed like a straightforward fix. how's it working? it snaps in easily and does the job, keeping my floors clean, but it runs warm when charging, which is a bit off-putting. is it worth it? for the price, it's okay, but i'm not blown away; it gets the vacuum moving again, but i'm already thinking about how long it'll last. overall, it's functional but not amazing—just a basic replacement that does what it says, with a few quirks.
- Pros: it fits perfectly into my vacuum, just like the original, and charges up pretty quickly, which is handy when i need it ready to go. the runtime is decent, lasting through a full cleaning session without dying on me, so no more mid-clean surprises.
- Cons: it gets quite warm during charging, which makes me a bit nervous about long-term use, and while it works, it doesn't seem to hold a charge as long as i hoped—maybe it's just me, but it feels like it drains faster than expected. also, the initial setup was a bit fiddly, not as plug-and-play as advertised.
