TG T54FJ 60WH M5Y0X E6420 E5420 Replacement Laptop Battery for Dell Latitude E5420 E5520 E5430 E5530 E6520 E6420 E6530 Inspiron 4420 5420 5425 7420 7520 M421R M521R N4420 N4720 N5420

Works fine. I was told by a tech friend that it wouldn't but it does.

I just got the battery in the mail to replace my dead laptop battery. I popped it in and waited for it to charge so I could print out some things. It charged in only 25 minutes!! I'm impressed so far!!

Works well, holds charge long time

The Dell Latitude 6420 is business-scale laptop and a workhorse with a long life. So of course, the OEM battery will eventually give out, as mine did. I ordered a replacement battery five months ago on Amazon from the XYT-TECH Store. Installation was easy. I just did a BIOS check on the battery, and it was rated good. I use the battery almost every day. I currently get around 2 hours of continuous use out of it reading news, texting, and a few videos here and there. I have no problem recommending this battery for purchase. I do think there may be a bug in the way the 6420 reads the battery charge. The battery reading can vacillate dramatically, with the charge going both up and down over my usual 2 hours of use disconnected from AC. It usually gives me a reading of about 3 hours a few minutes after I first unplug, dropping to about 2 hours remaining after 45 minutes or so of use. After about 90 minutes of continual use, it will fall to about 1 hour left of charge. From there, you better be ready to plug back in, because it can drop to critical (i.e., blinking yellow battery indicator) at just about any time from that time forward. That's my only real complaint, and as I said previously, it is probably not the battery's fault.

Quiero retractarme el dia de hoy 02/14/22 ya que acabo de recibir por parte directa de TG-Tech el reemplazo de la bateria que adquiri el 09/06/21 la cual llego mala y me di cuenta fue cuando me llego a Venezuela mi pasi de origen, justo ese dia me comunique con AMAZON y la unica manera de que me hiciesen el reemplazo era enviando la bateria mala pero estando en Venezuela donde las condciones de mi pais no son las mas optimas eso era un imposible por lo cual di por perdido mi dinero ya que no podia cumplir con los requisitos de AMAZON para la devolucion y reemplazo de la bateria, pero cual fue mi sorpresa que el dia 01/18/22 recibi una notificacion directa de fabricante donde me inicaba que me iban a reemplazar la bateriasin necesidad de que les enviara la bataria mala ya que consideraron mi situacion pais y me hicieron el envio a una empresa de envios puerta a puerta a Venezuela donde por casualidad me venia una caja para mi pais por maritimo y ya tengo la nueva bateria en mi poder y en correcto funcionamiento.Por todo lo expuesto anteriormente los califico con 5 estrellas porque lo mas importrante de las ventas de cualquier rubro es su servicio Post Venta asi no haya sido una respuesta inmediata pero lo importante son los resultados. Gracias desde Caracas Venezuela!!!!!

After 6 months, and with the charger connected, the battery frequently started indicating it was empty and very quickly forcing the laptop to turn itself off. I was forced to run the laptop just on the charger and without battery!

Ok so after looking for a replacement battery for my laptop I came across this battery. I read the reviews and some were good and some weren't. A lot said the battery life was short. Well I work on medical x-ray equipment and know it's always best to let your battery go completely dead then give it a full charge. This is to prevent the memory that can possibly happen which cause the battery to thinks it's 100% charges when it actually isn't. Also some reviews said the battery wasn't 100% charged when they received it. Really what battery that sits on a shelf comes 100% charged? None cause it's called leak down which is normal. So since I have had this battery it has worked perfect with no issues and I recommend anyone who needs it to buy it and just let it go totally dead the first day and then do a full recharge and will be fine from them on.

I'm really impressed with this battery. Buying replacement batteries can be a hit or miss situation, but I am really glad that this tuned out great. I got it installed and the laptop recognized it. got it charged and so far, it holds charge for considerable time when the power is out. Highly recommended.
