T440p Batteries

#1 Post by Dongers » Tue May 28, 2019 11:13 am

So, looking at next TP purchase, new daily driver to replace my still perfectly functional/serviceable X230 (Yes, I have the TP bug too) and I'm looking at the T440p

Had a T440 when was at last company and hated it (12Gb RAM max, Trackpad (ugh), swollen main battery (yes, i know that's really dangerous!))...not very upgrade-able tbf.

But the T440p looks like a very different beast, and as mod-able (almost) as a T420 or T430.

One question though, and I know I'm probably inviting flames by asking a somewhat sacrilegious question but....Aftermarket batteries...? Do they work or not..?

Know that the **30 Series has the EC mods from Hamish Coleman, but have seen 3rd Party batteries on fleabay and amazon for T440p and not sure how they can work without an EC Mod..?

Any ideas..?

Cheers

By now the aftermarket battery manufacturers mimic the Lenovo chip. They will work.
lenovo "Super" T420 i7 2670qm WQHD 16GB
lenovo T500 P9700 Radeon 3650 WUXGA 8GB
lenovo T601F T7500 NVS 140m SXGA+ 8GB

Yes, in general the aftermarket batteries are now compatible with the Thinkpad chip requirements. However, they are still mostly using junk cells. I've never had one last more than 6 months and many are worthless right out of the box!
