Perfect fit! Too easy!
Laptop was accidentally left in the rain... Wouldn't turn on. Took it apart and found just a little damage where the battery shorted out and smoked due to corrosion. Replaced the CMOS battery and reset the laptop CMOS and it came back to life! Quick, easy fix. Works like new.

Me parece que es una buena opción para remplazar la CMOS que tiene de fabrica, mi laptop es una Lenovo Thinkpap T430, previamente al usarla, tenia la problemática de que este se apagara sin razón sin retener la fecha y la hora, de momento veré cual es el rendimiento de esta CMOS, 📝 Lo compre con el proveedor RF Official entregado por la paqueteria de AMAZON, llego perfectamente protegido en una caja grande a pesar de que el producto es pequeño, llego en tiempo y forma según lo programado 👍🏳
