I think that this is not linked to the quirks.
Quirks are here: https://github.com/zigpy/zha-device-handlers/blob/b98948e7b6538ab31d87330bba1793e0eb65de11/zhaquirks/ikea/blinds.py
The replacement part is the same. There are two quirks only because blinds don’t have the same signature.
So maybe it does not have the same internal components. Were you able to compare batteries specs?
