is my new non-oem battery dead or dormant

[Lox]

Hi, i have a non-oem battery thinkpad 70++(6 cell) which has a voltage of 10.8. When I plugged in the ac adapter which is a 65w 20v charger,
the battery is not being detected. I tried reinstalling power manager, which also says the same thing, battery not detected. The thinkpad battery eeprom updater also says the same thing. Currently I am trying to do the freezer method, I tried to do it out of desperation.

edit: the charge controller works, i have a board from an old battery to test it.

model 2537-LV6 T410

it appears that the battery says 11.8v instead of 10.8, on the model I realised that it says t430, but thinkpad battery are interchangeable right?

Try a 90W charger, and/or try the battery in another system.
Also, some BIOSes (T430/T530/W530/X230 and upwards) have a checker built-in that won't charge batteries that are not specific for that model.

Not all X230 batteries will work in a X220, although I believe all X220 will work in X230. May be the same for the T420.

It's the other way around.

A 70++ should work in all laptops with whom it's physically compatible.

Yes sir, you are correct, early morning fog clouded my thinking.

I'm currently ordering the mentioned charger. I forgot to tell my model a T410 2537-LV6 with modded bios, whitelist disabled 6IET85WW (1.45)
I flashed without a battery

When you say non-OEM, where exactly did you procure it from? There's some Chinese fakes that look like the real deal but just won't charge.

[TPFanatic]

Cheap aftermarket batteries are hit or miss, can be unreliable, and I wouldn't rule out sudden death being the battery's fault before the Thinkpad's. Try to get another, or a used genuine one. T410, newer 20, or newest 30-era original batteries are still young enough to be useful.

I found that sometimes the battery, oem or non oem sometimes needs a boost from a 90w or better charger.

65w is enough if you're using it day to day but if you let the battery go deal flat...
