Ultra bay extra battery

#1 Post by Eto » Thu May 03, 2018 7:37 pm

What ultrabay battery fits the thinkpad T510/W510?

Which of these, (if you know) is the correct part number? 45N1041, 51J0508, 57Y4536, 41U4890, 51J0507, 40Y6787

Also is it worth it as far as extended time/charge?

AFAIK, none. The only units in the 10/20/30 series that support Ultrabay batteries are the 14" slim T series (400s/410s/420s/430s).
Current: Thinkpad 25 (20K7), Yoga 14 (20FY), X220 4291-4BG, T410 2537-R46, T60 2007-QPG, T42 2373-F7G
Collectibles: T430s (IPS FHD + Classic Keyboard), X32 (IPS Screen)
Retired: X61 7673-V2V, T60 1952-F76, A31p w/ Ultrabay Numpad
