Easy&Fine PA5157U-1BRS Battery for Toshiba Satelite U940 E45T E45T-A4100 E45T-A E45T-A4200 E45t-a4300 E55 E55T-A5320 E55-A5114 15.6" PA5157U P000577250 [11.4V 50WH]

Battery was easy to install and worked phenomenal on first uses. I was getting 7-10 hours of battery use for general use. Right after the 60 day mark of no return however the battery started failing. I initially thought it was a driver or some kind of battery firmware issue. Exhausted that routr with no success. Thrn noticed there is extreme amounts of heat coming from it that is causing my computer to stutter and freeze and the battery now lasts under 10 minutes and I wound up having to remove it to prevent the heat sink from damaging other components in the computer. Will have to buy another battery but will be choosing a different seller.

Fue lo esperado, recién la instalé y espero que funcione correctamente !!!! gracias!!!!!

Works great!!

The battery lasted a few hours. Complete trash. Don't waste your money. You're welcome.

Worked out of the box, having had one battery shipped me a ride from another company that filled, that was a pleasant surprise. Time will tell but so far so good.

I did not like how the product description was the wrong voltage and Milla amps

Al paraecer se observa de buena calidad, estoy pendiente de hacerle pruebas.

Great product with great quality! Easy to install, fits perfectly, and excellent performance.
