It was good experience, the laptop battery was excellent and it was a good deal with this price, this was a replacement battery for my Dell Inspiron 15R 5522 model and there was no issues in fitting it.

This Battery is cpmpatible with my DELLInspiron 15 3542. I installed this Battery (XCMRD) yesterday (23/06/2026). It is working fine so far and gives back-up for 2 and a to 3 Hours so far. Initially after installation, I allowedthe battery to discharge upto 20% and charged fully. This process was repeated thrice. It is working fine so far and I dont know how long. I wanted to give 5 Star rating but gave 4 Star just because of the long time taken for delivery. Qualitywise it is fine.
