I have a thinkpad t430s and I bought a new supposedly oem lenovo 43 ultrabay battery. When I insert the battery it is recognized that a battery was plugged in but it stays at 0%. I've tried all different combinations of reinserting it before and after reboots turning on and off the ultrabay in the bios. The CD / DVD ultrabay drive works fine, although since the connectors inside are totaly different I doubt that is relevant info.

What is the best way for me to figure out if the problem is this battery or the laptop? Or could it be a software issue...

any help would be hugely appreciated. One of the main reasons I acquired this laptop was the use of the ultrabay batteries.

Thanks

Some of the old machines would charge the secondary battery only after the primary battery was charged 100% first, or u could remove primary battery and see if it charges then.

thanks for the replies.

Tried removing the primary with no change. Probably is a dead battery. Going to be terrible returning it to china lol. Cant find a local source that sells the battery in canada.

For the hell of it I ordered a external battery charger.

You cannot just replacer the cells on these batteries. The controller with set a permanent failure flag when a cell died. Disconnecting working cells will also trip that. You will need to reset the controller chip through SMBUS commands and most of them are locked with password. All of this is not feasible for on off projects.
