NinjaBatt Battery for Dell MR90Y XCMRD Inspiron 3521 15R-5537 Latitude 3440

The battery started my laptop straightaway and close inspection showed it was good quality.

4 stars (one less) because of the price. Otherwise a good product

Easy to install battery life remains to be seen but at this price it doesn’t really matter. Came 75% charged. Great after service they even sent an after sale email whiCh include a handy guide as to how to conserve battery life. Would recommend.

Bought this for my son’s refurbished Dell laptop, but annoyingly it’s stopped working after just 3 months! Complete waste of money. Amazon said it was outside the incredibly short 1 month return policy. So I spoke to an actually human rather than a bot and they have agreed to giving me a full refund.

Working well. No issues so far!

The shape of the battery is slightly thicker in this non-OEM part, but that is used to a good effect, as it angles the keyboard, ever so slightly up, at the back, probably no more than 5mm(ish!) and so I wasn't too fussed about that. I had read reviews about other batteries not fitting well and discarded those from my purchase plan, settling for this battery that had positive reviews that I found to be accurate and beneficial. The battery came partially charged (to about 80%) and it didn't take long to get that to 100% before I started using it. From there I used my laptop for about 60-70 minutes and when I checked it before shutting down, it was at 94% with a suggested 8 more hours of use. I appreciate that new battery cells hold their charge for longer than the OEM one I'd had for about 6-7 years (Dell's battery, REALLY lasted well, in my opinion) and time will tell if this remains to be a solid purchase. Worthy of your consideration and a strong 5 stars at the start.

Arrived promptly and works as it should.

Very good

This battery was a perfect fit for my DELL Inspiron 15 (BattType: XMCRD 14.8v) We had previously ordered a battery from another amazon vendor which was dead on arrival. It wouldn't take a change and gave failure warnings every time I booted up. I returned that battery to Amazon and decided to order a Ninja Battery. I am now extremely satisfied. The Ninja battery came 50% charged (as it should) and after installation it continued to charge to 100%. After multiple charge/discharges, it continues to perform perfectly.

Pour débuter, un service client impeccable. J'ai envoyé un courriel en posant une question avant d'acheter le produit et on m'a répondu en moins de 24h. L'information transmise était claire et répondait à mes attentes. J'ai ensuite commandé le produit. La livraison a été vraiment rapide; plus tôt que prévus même. La batterie est parfaite pour mon portable, fonctionne très bien et se charge rapidement. Le meilleur prix que j'avais trouvé était 72$..... donc un bon achat pour ma part. Si vous êtes comme moi, sans aucune connaissance des pièces informatiques, écrivez-leur, ils sont gentils et efficace.

Goede kwaliteit

I finally did a “proper” test of the battery. I used the fully charged laptop disconnected for almost 6 hours until it showed 20% of battery left and then I plugged it in again. I used it normally for browsing internet through wi-fi and writing text in MSWord, with normal (more than half) screen brightness. I did not listen to music or did any other high-processing-needs task. Still, I’m impressed. The battery is also not bulky as other higher-capacity batteries out there. You barely notice it rises a little from the flat surface of the body. It fits very well, and so far I had no problems with malfunctioning whatsoever. I certainly recommend it!
