  Exactly as described on the tin
Wolf Gray from USA, Hampton, VA
It's a battery, with a standard CMOS connector. Completely compatible with the 2012 Razer Blade Pro it was put in (except thickness. This is thicker than the original.) On the Dell M6400 it worked even though the original socket was 3-wire. Antique computers, what can you do?


  works fine
nelson from san deigo, ca
good quality build, fast shipping. Replacement for Intel NUC battery, however, the intel board had the pins reversed, easily repinned the connectors.
