Its correct. Check Manufacture Name. Battery produced by Samsung and this is their safety feature - untill battery is inserted in laptop noone could unseal it to make changes to safety settings. Sometimes hackers trying to get access to battery charging and safety profiles to make dirty things with it, so that feature prevent this attack vector. Only authorised personnel in workshop could reprogram the battery.

This chip is not supported. You should attach the dump here to fix it.
