1. Did you change the TYPE or SIZE of battery? REGISTERING later is OK, changing other things no. Looking at the pictures it seems it is an AGM for AGM, so that's ok...and the 90Ah vs 95Ah is perfectly fine too. A 5% difference is in the noise. Internally they are probably identical, made by the same factory I'd bet.

2. Was the new battery fully charged? Did you drive/let it charge for 2-3 hours after install? Taking a battery that has been sitting for months on a shelf may be installing a borderline unit

3. I'd attach an AGM charger and charge it overnight
