my old vacuum battery was dying fast, leaving rooms half-cleaned, which was frustrating. i bought this on a whim after seeing it online, hoping for a quick fix. it arrived fast, and installation was straightforward—just swapped it in. now, the vacuum runs much longer and stronger, tackling my whole house without conking out. it feels like a solid upgrade, very reliable so far. not perfect, but a huge improvement that solved my problem well.
- Pros: this battery really brought my vacuum back to life, it feels very powerful and lasts a long time, making cleaning sessions much more efficient. i like that it's not heavy or big, so it's easy to handle, and it seems safe with all the built-in protections, which is a big relief.
- Cons: it was a bit pricey for what it is, and i had to make sure it fit my specific vacuum model, which took some extra checking. also, the performance boost is great, but it didn't completely eliminate the need for frequent charges in my large home.
