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

Works well, holds charge long time

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!!

Easy install, worked great and fit perfectly. I'm happy with it. Not sure what else to say. It's a good deal

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!

Muy duradera.

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.
