Very very Good

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. On 100% charge it was showing a backup time of 2hrs and 25 mins. Over all a good deal with this price.

Really the Techie battery was awesome performance it's very light weight nice.
Thank you so much for Techie store!!

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.

Good, affordable OEM parts

I thought, I will not get a battery for my old dell laptop. But Techie solved the problem. Very easy to find the compatible battery. The delivery was fast and the battery is perfectly giving it's performance.

Just using the battery for the past 3 days and it seems to be working very well. No heating issues and battery charging is super fast. Battery back up is also quite good for the moment. So far no issues at all. Need more time to check battery longevity and durability which I'm sure will pass the test too.
