T400 2nd battery

2008-10-06, 19:00 PM



I am considering buying a T400 and have a question. Does anyone know if a ultrabay or slimbay (whichever is the right one for a T400) 2nd battery is available or is planned?


The pages to order the T400 list a 2nd hard drive caddy but I saw no 2nd battery.

I show a 43R9250 as Advanced Ultrabay Battery II 3-cell battery used in Ultrabay Slim bay. 


This is a Lithium Polymer Advanced Ultrabay Notebook Battery. 


The ThinkPad Advanced Ultrabay Battery II is a rechargeable battery that fits in the ThinkPad Ultrabay device bay. Together with the system batteries, it can extend user mobility and unplugged computing time. Battery life (and recharge times) will vary based on many factors including screen brightness, applications, features, power management, battery conditioning, and other customer preferences.
