N3X1D T54FJ 8858X M5Y0X E6420 E6430 Laptop Battery for Dell 65Wh

This is an updated review. I purchased this product in April before some of the reviews were available, saying that it does not work with the Dell E6540, my laptop. I experienced the same bad performance as other reviewers with the first battery that I received, and I wrote a highly critical review of the product. The seller responded immediately with an offer to send me a new battery. I received it in just two days and I am now very satisfied. The battery was fully charged in less than one-half hour and is performing flawlessly. I suspect that my initial battery was defective, but the seller did the very best that she could to solve the problem. I commend her for outstanding customer service and can now recommend the product without reservation.

i recieved this battery ontime ,i snapped it in and it started worked as soon as itcameon i did few things onlaptop then put it on charge im very satisfied with this battery

great product

I purchased and installed this battery in June, by November it was not holding charge anymore. It did not even last 6 months. Only 1 month return period but I reached out to the seller and she sent a replacement. She told me that if it did not work she would refund us. I have made a note on my calendar to take note in 3 to 6 months on how charge is holding, Very impressed with this seller's efforts to make it right!

I purchased this battery as a replacement for my older dell E6440 to keep it running again as the factory battery finally gave out and this battery works wonderfully. It's like back when it was new with battery life.

Batería de muy buena calidad

When I first received my batter I was SO excited since my other aftermarket battery stopped taking charge, and also my Dell computer didn’t recognize the battery. First when received I put it in, my computer did an automatic update for whatever reason, when stated my battery was critically low. Once it started up, my Dell started the cleaning process, then stated that my ax adapter was unrecognizable. So once it finally turned on and I was able to log in, my battery stated it was at 0%… not even charging whatsoever. Computer doesn’t even recognize this piece of JUNK. I don’t know why the other reviewers are lying because I have a worthless buy. I rather just buy the actual Dell batter cause this one SUCKS. Do NOT buy I will be getting a full refund!!!

The battery works fine but I ran into that problem with most Dell computers. They make everything so damn proprietary that the battery isn't recognized by the laptop as an official Dell battery and it wants to reboot or shut down the laptop occasionally. This becomes a problem when you are in the middle of doing something and the laptop shuts down because of the battery not being recognized by the Dell laptop

Purchased this Amanda N3X1D battery for my E6420 XFR on June 22nd 2025. It arrived the next day as expected. Right out of the box, the Battery Management System (BMS) reports it's 42% charged. BMS states the designed capacity is 55.5Wh / 5000 mAh. The last know full charge capacity out of the box states 58.8Wh. This is expected as new cells typically has slightly higher capacity than the designed capacity on day 0. I then gave it a full charge, full discharge, full charge workout (i.e. manual battery re-calibration). It can hold a total of 60.0 Wh. Really impressed with the numbers. I never expected it to be a 65Wh to begin with, and had considered that a typo in product details when I placed the order. So when the BMS says 55.5Wh designed capacity, that's completely within my expectation of '56Wh'. Now that it's recalibrated and confirmed it can hold 60.0Wh on day 1, I would say it's well worth the CAD$40.

Comme c'est la première fois que je devais remplacer la batterie de mon laptop, j'ignorais que je devais la charger. J'ai demandé de l'aide pour savoir ce que je devais faire pour la charger, on m'a transmis le lien de la compagnie pour les contacter, ce que j'ai fait mais je reçois la réponse que je serai contactée dans quelques jours. Je ne suis pas super intelligente au niveau informatique mais je ne suis pas complètement nounoune. Si on m'avait dit que je n'avais qu'à attendre et que le chargement se ferait automatiquement, j'aurais compris. Je l'ai découvert par hasard. À force de chercher, j'ai réalisé que la batterie se chargeait automatiquement.
